Skateboard Bearings Buying Guide

Skateboard bearings are a crucial component for anyone who rides a skateboard, longboard, cruiser, or surfskate. They are essential for ensuring the proper functioning of the wheels, significantly contributing to the overall performance of your skateboard.

The working principle of bearings is surprisingly simple yet vital for your skateboard. Bearings consist of a set of metal balls, typically made of durable steel, housed inside a cage designed to keep the balls aligned. When you spin the wheel, these balls rotate within the cage, dramatically reducing friction. The result? The wheels spin smoothly and quickly, allowing you to achieve optimal performance.

Standard Dimensions of Skateboard Bearings

One aspect that makes purchasing bearings much easier is their standardization. Specifically, bearings of this size are classified with the number 608. So, you don’t need to worry too much about sizing when shopping for skateboard bearings.

All skateboard bearings with a 608 classification feature an inner diameter of 8 mm, an outer diameter of 22 mm, and a width of 7 mm. These dimensions perfectly fit the wheel axles of your skateboard.

The ABEC Rating: Real Gold or Just Glitter?

Before diving into the key components of skateboard bearings, let’s clarify the infamous ABEC rating.

The ABEC ratings represent a measure of tolerance, a term that may sound technical but is essential for understanding the nuances of bearings. The acronym ABEC stands for Annular Bearing Engineering Committee. This classification refers to the precision with which the various components of a bearing fit together. Greater precision means a more smooth and efficient bearing.

The ABEC scale is numerical, ranging from 1 to 9 and only includes odd numbers. These numbers indicate the precision of the bearings, with ABEC 1 bearings being the least precise and ABEC 9 bearings achieving maximum precision. However, it’s important to note that a higher ABEC rating does not necessarily mean greater speed. The ABEC rating is just one of many aspects that define a bearing.

It’s crucial to understand that the ABEC rating is limited to measuring dimensional tolerances during manufacturing. This means it doesn’t provide any information about a bearing’s load capacity, maximum speed, materials used, or type of lubricant. In the skateboarding world, all these factors are far more critical than dimensional tolerances.

To give you a clear example, imagine an ABEC 9 bearing. If this bearing has to support the weight of a skater weighing 100 kg, it will perform differently compared to when the same bearing supports a skater weighing 50 kg. Even without any skater on it, performance can vary significantly. Additionally, if this ABEC 9 bearing is made of steel, it will perform differently than one made of plastic. The ABEC rating provides only a small glimpse into a bearing’s performance.

It’s worth noting that ABEC ratings were originally designed for industrial applications, where bearings operate in controlled environments. Below, you’ll find the actual ABEC tolerance measurements, but keep in mind that in the skateboarding world, these measurements often take a backseat to other critical aspects.

TypemmInches
ABEC 10.0075 mm(0.000295")
ABEC 30.0050 mm(0.000197")
ABEC 50.0035 mm(0.000138")
ABEC 70.0025 mm(0.000098")
ABEC 90.0012 mm(0.000047")

What does the ABEC rating truly represent in the skateboarding world? And what does it mean for your favorite skateboard bearings?

It’s fair to say that a tiny speck of dirt in your bearing can completely negate the prestigious ABEC label. When it comes to buying skateboard bearings, it’s crucial to understand that these components face harsh skateboarding environments. So, investing 2 to 4 times more for an ABEC 9 bearing might result in only a fleeting advantage.

That’s not to say you should settle for ABEC 1 bearings. Bearings with a higher ABEC rating often use better materials and lubricants. These factors can significantly impact the bearing’s performance over time, especially when exposed to the rigors of skateboarding. Higher ABEC ratings often correlate with higher-quality bearings because they are usually made with premium materials and superior lubricants. However, the most common mistake is to attribute a bearing’s quality solely to its ABEC rating.

ABEC 7 Skateboard Bearings

Still, if you’re determined to choose your bearings based on ABEC rating, here are some technical tips:

  • ABEC 1 or ABEC 3 Bearings: These ratings indicate rough and less smooth bearings. While they are cheaper, they might not be the best choice for such a critical skateboard component.
  • ABEC 5 Bearings: These bearings are a common choice for traditional skateboarding. They offer a good balance between speed and durability.
  • ABEC 7 Bearings: Often used on cruisers and suitable for classic skateboarding, these bearings are quite fast and smooth. They are ideal for city skate sessions.
  • ABEC 9 Bearings: Precision and speed are the hallmarks of these bearings, which allow for smooth wheel rotation. They are often installed on longboards designed to tackle long distances with ease.

Remember, when it comes to skateboard bearings, the ABEC rating is just one small piece of the puzzle. Your final choice should consider many other factors, including materials, lubricants, and, of course, the brand you choose. So, when you make your final decision, keep in mind that it’s not just the number that matters, but the experience you want to achieve on your skateboard.

The Revolution of the "Skate Rated" Classification

Have you ever heard of the "Skate Rated" classification? This term was coined by the innovative company Bones Bearings to challenge the often misleading traditional ABEC scale.

The leading bearing manufacturers are well aware that the ABEC rating is just one of many factors to consider when choosing bearings, and they strive to distance themselves from it. Why? To avoid reducing the quality of their bearings to a mere comparison with those of another company based solely on the ABEC rating. The best skateboard bearing companies go above and beyond to optimize their products for the skateboarding environment, and this excellence cannot be captured in a simple ABEC evaluation.

'Skate Rated' Skateboard Bearings

Since the term "Skate Rated" is also a registered trademark of Bones Bearings, in our online store, we have adopted the name "Skate Tested" for all those bearings that, like Bones Bearings, choose to step away from the ABEC scale. These bearings are specifically designed to meet the demands of skateboarding, ensuring exceptional performance.

With "Skate Tested" bearings, you can be confident that you're investing in the best technology the skateboarding world has to offer.

Main Components of Skateboard Bearings

To purchase the perfect skateboard bearings for your needs, it’s essential to understand their anatomy. Familiarizing yourself with the various parts involved will help you make more informed decisions when choosing your set of bearings, whether it’s your first purchase or an upgrade.

Skateboard and longboard bearings are constructed using five distinct components:

  • Balls: The balls inside the bearings can be made from various materials, including steel, titanium, or ceramic. Their quality and precision directly influence the performance of the bearing.
  • Outer Ring: The outer ring serves as the outer raceway for the balls. Its shape and craftsmanship significantly impact the bearing's resistance and durability.
  • Inner Ring: The inner ring is the inner raceway for the balls. Its quality and precision also play a vital role in ensuring the balls' smooth rotation.
  • Shields: Bearings can have one or two closures, commonly referred to as shields or rubber seals. These components protect the balls from debris and dirt, helping to maintain the bearings’ optimal performance over time.
  • Ball Retainer or Cage: The ball retainer or cage holds the balls in alignment and prevents them from rubbing against each other. Its quality is crucial to ensuring the smooth functioning of the bearing.

Each component plays a vital role in the reliability and overall performance of the bearings. Read on to discover how these parts affect your skate sessions and how to choose the ideal bearing set for your riding style.

Skateboard Bearing Balls: Ceramic Vs. Steel

The bearing balls are the beating heart of these essential skateboard components, and this is where one of the most heated debates in the skateboard bearing world arises: ceramic or steel?

Ceramic Skateboard Bearings

Ceramic bearings are renowned for their ceramic balls, which are considered superior due to their higher durability and smoother surface compared to standard steel balls. While these bearings are significantly more expensive, their price doesn’t necessarily translate into better performance.

It’s important to note that "ceramic" refers only to the balls within the bearings, while the inner and outer rings are still made from chrome or stainless steel, creating hybrid bearings.

The tangible advantage of ceramic over steel is its corrosion resistance, meaning it is less prone to rust. However, since ceramic bearings are hybrids, the inner and outer raceways are still susceptible to corrosion.

Another advantage of ceramic balls is their lightweight nature, which reduces friction and allows for greater acceleration and speed. Ceramic bearings are generally considered high-end and are favored by professional or advanced skaters. However, their higher cost makes them less accessible for beginners or casual skaters.

Steel Skateboard Bearings

Skateboard Bearings with Steel Balls

Skateboard Bearings with Steel Balls

Most skateboard bearings are made with balls, an inner ring, and an outer ring constructed from chrome steel, sometimes referred to as carbon steel. Steel is known for its ductility and elasticity, allowing it to retain its original shape even under heavy loads. Additionally, it is a relatively affordable material, with quality bearings priced between 15 and 30 euros per pack.

The components of a steel bearing are polished and smoothed to minimize friction. Steel requires the application of lubricants to allow the parts to move smoothly under load and to protect them from corrosion (rust).

Most skateboard bearings are made from chrome steel, but there are stainless steel (Inox steel) variants, with balls and sometimes raceways made of this material. Stainless steel is more resistant to rust, making these bearings suitable for skating in wet conditions. However, stainless steel is softer than chrome/carbon steel, which means stainless steel bearings may not last as long.

Our recommendation is to opt for chrome/carbon steel bearings and maintain regular cleaning of your bearings. Alternatively, you should avoid skating on wet surfaces to preserve the longevity of your bearings.

Swiss Skateboard Bearings

Swiss bearings, also known as Swiss Bearings, represent the pinnacle of quality in the skateboarding world. These premium bearings have a storied history rooted in Switzerland, thanks to Bones Bearings, which first introduced them in 1983. The name "Swiss" pays homage to their origin, as these bearings were initially manufactured in Switzerland. However, it’s worth noting that other manufacturers have adopted the "Swiss" label for their high-quality bearings, but the actual quality may vary by brand, and production may not necessarily occur in Switzerland.

Swiss Bearings are distinguished by top-tier materials and extremely precise craftsmanship, resulting in superior durability and longevity compared to standard bearings. Their hardened steel balls and precise construction provide an incredibly smooth ride and enhanced acceleration. Another standout feature of "Swiss" bearings is their deeper raceways compared to standard bearings. This allows the entire bearing to handle lateral loads more effectively, granting Swiss bearings significantly greater durability. Other bearing manufacturers may refer to this feature as "deep groove" or similar.

Swiss bearings are a top choice among professional skaters and those who refuse to compromise on quality. These bearings deliver an exceptionally smooth ride, enhanced durability, and longer-lasting performance compared to standard options. However, this level of excellence comes at a slightly higher price point. When you choose Swiss bearings, you’re investing in a component that can transform your skateboarding experience, offering quick acceleration and unparalleled smoothness.

Open, Closed, or Semi-Closed Bearings

Skateboard bearings come in three distinct configurations: open, closed, and semi-closed. In this section, we’ll explore the key differences between these options and how they impact your skateboarding experience.

Open Bearings

Open bearings lack side shields, providing a "no-frills" riding experience but requiring careful consideration. The absence of protective shields leaves the bearings more exposed to debris and dirt, meaning they require more frequent cleaning and maintenance to ensure durability. If you prioritize maximum acceleration and are willing to invest time in regular upkeep, open bearings might be the right choice for you.

Open Skateboard Bearings

Closed Bearings

Closed Skateboard Bearings

Closed bearings feature protective shields on both sides. This configuration offers complete protection against debris and external contaminants, significantly extending the lifespan of the bearings. It’s worth noting that closed bearings can still be cleaned, depending on the type of shields used. Some bearings have metal shields, while others use rubber seals. High-quality bearings typically come with two protective shields, ensuring optimal protection.

Semi-Closed Bearings

Semi-Closed Skateboard Bearings

This configuration blends elements of open and closed designs. Semi-closed bearings have a protective shield on one side only. While this offers partial protection against external contaminants, dirt and debris can still enter from the unshielded side. Semi-closed bearings might suit those seeking a balance between durability and performance, but it’s important to understand the trade-offs.

Bearing shields not only protect against external debris but also help retain lubricants inside the bearing. It’s crucial to note that a "closed" bearing doesn’t necessarily mean its shields are non-removable for cleaning. This depends on the type of shield used. Pressed metal shields are usually non-removable, whereas metal shields with a c-ring and rubber seals can often be removed for easy maintenance. Later, we’ll explore the different types of shields available for skateboard bearings, helping you make the most informed choice for your needs.

Open Skateboard Bearings: Maximum Speed, Minimal Hassle

Open skateboard bearings are the bold and determined choice of true skaters seeking the essence of speed and absolute simplicity. They embrace the idea of raw power and a direct connection between your skills and the surface you’re skating on.

If you crave the thrill of dominating the pavement at breathtaking speeds, open bearings are for you. These bearings are completely shield-free, meaning zero friction caused by protective covers. And what does zero friction mean? Pure speed and unhindered acceleration.

Sure, they might be noisier than shielded bearings, but that hum is the music of high speed—the symphony of your passion on the board.

Open Skateboard Bearings

The real beauty of open bearings lies in their incredibly straightforward maintenance. There’s no need to remove wheels or perform complex operations. All you need is a small bottle of bearing lubricant, and you’re ready to roll. After each session, just add a drop of lubricant, and you’re good to go. Simple, fast, and hassle-free.

There’s one thing to keep in mind if you choose this high-speed path: consistent lubrication. Be prepared to carry a bottle of lubricant with you at all times. After all, keeping your secret weapon in peak condition is the key to dominating any road.

Among the most renowned shieldless bearings, the famous Bronson Raw stand out. They are the choice of skaters seeking maximum adrenaline without distractions.

Closed or Semi-Closed Bearings: Metal Shields vs Rubber Seals

Bearing closures play a crucial role in protecting and maintaining your skateboard bearings in excellent condition. These "defensive barriers" can be compared to walls that prevent unwanted debris from entering while keeping the lubricants securely inside the bearing. Typically, skateboard bearings are equipped with closures on one or both sides, and these closures can be made of metal or rubber.

Metal shields come in two types: pressed metal shields, which cannot be removed, or removable metal shields with a c-ring. These shields provide significant friction reduction, resulting in greater speed while skating. However, their resistance to water and dirt may not be optimal.

Skateboard Bearings closures

On the other hand, rubber seals offer superior protection and require minimal maintenance. These seals come in three variations: light contact rubber seals, non-contact rubber seals, and labyrinth rubber seals.

Skateboard Bearings with Non-Removable Pressed Metal Shields (608Z or 608ZZ)

Skateboard bearings with non-removable pressed metal shields, identified by the codes 608Z or 608ZZ, are typically the most economical option. These bearings feature one or two metal shields that cannot be removed. A defining characteristic of this type of bearing is the small gap between the shield and the inner race, usually concealed by a nut or speed washer. This minimal initial clearance allows metal-shielded bearings to deliver high initial speed, as they encounter no resistance from their shields. Surprisingly, they are also quite effective at repelling dirt. However, it's worth noting that they are less effective at protecting against damage caused by moisture. Consequently, the speed of these bearings may suffer in wet conditions.

We recommend 608Z or 608ZZ metal-shielded bearings for riders on a budget who prefer skating in dry conditions and are willing to replace bearings more frequently rather than cleaning them. Most bearings of this type come equipped with two shields for additional protection.

608Z Skateboard Bearing

Skateboard Bearings with Light Contact Rubber Seals (RZ)

Skateboard bearings with light contact rubber seals feature a unique design and are identified by the codes 608RZ or 6082RZ. Along the inner edge of the rubber shield, a thin rubber lip lightly touches the bearing's inner race. This specific configuration of rubber seals does an excellent job of protecting the bearing and retaining lubricant inside. Additionally, the "light contact" effect between the seal and the inner race does not significantly reduce speed during skateboarding.

608RZ  Skateboard Bearing

Skateboard Bearings with Non-Contact Rubber Seals (RS)

Skateboard bearings of type 608RS or 6082RS are equipped with rubber seals that do not make direct contact with the bearing's inner race. Along the inner edge of the rubber shield, there is a thin rubber lip that does not touch the inner race of the bearing itself. This slight gap between the inner race and the rubber seal minimizes resistance. Skateboard bearings with this type of rubber shielding are an excellent choice for keeping out dirt and debris, outperforming metal-shielded bearings in this regard. However, it is important to note that, similar to their metal-shielded counterparts, they may allow water ingress, requiring regular cleaning if you skate in wet conditions. Removing the rubber shield is a simple process: just slide the tip of a utility knife between the inner race and the shield, and lift it for cleaning. Bearings of type 608RS or 6082RS are particularly suited for riders who prioritize maximum speed and do not intend to skate on wet surfaces.

608RS  Skateboard Bearing

Skateboard Bearings with Labyrinth Rubber Seals (RSL)

Skateboard bearings equipped with labyrinth rubber seals, identified by the codes 608RSL or 6082RSL, feature a specialized shield that provides excellent protection. This shield is wider and makes contact with both the inner and outer races of the bearing. The rubber protective shield is positioned within a V-shaped or U-shaped channel carved into the inner race of the bearing. This design makes the labyrinth seal highly effective at keeping out not only dirt but also moisture, earning its reputation as a "full-contact bearing shield." Bearings with labyrinth shield technology require significantly less maintenance compared to RS or Z-type bearings. It is important to note that the labyrinth shield, by contacting both the inner and outer races, may theoretically cause a slight reduction in speed due to resistance. However, this reduction is so minimal that it is unlikely to be noticeable during use.

608RSL  Skateboard Bearing

The only drawback of the labyrinth shield is its removal, which requires a bit more care and precision compared to other types of shields. A careless removal could damage the bearing. Therefore, we recommend labyrinth shields for skaters who want to maximize the longevity of their bearings, even if it comes with a negligible reduction in speed.

Skateboard Bearings Protective shields

Protective shields, such as rubber seals and metal shields, play a crucial role in skateboard bearings. These devices not only significantly extend the lifespan of the bearings but also help maintain their optimal performance over time. However, it is important to note that most bearings are sold with only one shield or seal, primarily to keep costs down. High-quality bearings, on the other hand, often feature two shields, which provide substantial advantages.

For bearings with a single protective shield, it is recommended to mount them so the open side faces the inside of the wheel. This practice can help protect the bearing components from dirt and corrosion, albeit to a limited extent. It is worth noting that, while the wheel itself provides some protection for the bearing components, there is still a very narrow gap between the skateboard truck axle and the bearings. This small gap can allow contaminants to enter the wheel assembly. Once contaminants infiltrate the wheel assembly, if no seals are in place to block them, the bearings can become dirty. Additionally, a minimal amount of lubricant may escape from the skateboard bearings and end up on the truck axle. Labyrinth rubber seals can help reduce this issue, although they do not eliminate it entirely.

In conclusion, to ensure greater durability for your bearings, we recommend using bearings with two shields. This choice will significantly improve the reliability and longevity of your skateboard bearings.

CodeShield Type
608 Z1 non-removable pressed metal shield
608 ZZ2 non-removable pressed metal shields
608 ZS1 removable metal shield with c-ring
608 2ZS2 removable metal shields with c-ring

608 2RS2 removable non-contact rubber seals
608 RSL1 removable labyrinth rubber seal
608 2RSL2 removable labyrinth rubber seals

Table with commonly used codes to identify the type and number of shields. For example, "608Z" indicates a bearing with a single non-removable pressed metal shield, while "6082RSL" refers to a bearing with two removable labyrinth rubber seals.

Remember that you can use the "Bearing Shield" filter to select the bearing models with the type and number of shields best suited to your specific needs.

Inner and Outer Rings of Bearings

Skateboard bearings are precision-engineered machines designed to provide a smooth and fast ride. Understanding the details of the inner and outer rings is essential to optimize your performance and ensure the longevity of your bearings.

The inner and outer raceways, commonly referred to as the inner and outer rings, form the core of skateboard bearings. These surfaces allow the balls to move fluidly, enabling you to glide effortlessly on your skateboard.

These raceways are made of high-quality steel, ensuring maximum durability and strength. They are designed to withstand the constant stress and wear of skating, but there is an important note to keep in mind.

Skateboard bearings are not designed to handle intense lateral loads. When lateral pressure is applied to the bearing, the inner and outer rings tend to separate, creating stress that could damage the balls. To prevent this issue, we highly recommend using spacers and bearing washers. These small devices help maintain alignment between the inner and outer rings, preserving the health of your bearings during intense sessions.

Inner and Outer Rings of Skateboard Bearings

Balls Retainers

Balls retainers, often referred to as "cages" or "crowns," play a critical role in skateboard bearings. These components work to evenly space the balls around the raceway, ensuring smooth and uninterrupted movement.

Balls retainers can be made from various materials such as nylon, steel, or brass. Each material has its own distinct characteristics:

  • Nylon retainers provide a low coefficient of friction, making the bearings ideal for speed. However, they are less durable than metal retainers and may not withstand rough road conditions as well.
  • Steel or brass retainers are more robust and suitable for handling rough terrain. However, they may have a slightly higher coefficient of friction, which could affect speed.

  2. Ball Retainer Cage

There are also differences in how ball retainers can be removed. Some, known as "cages," are permanent and cannot be removed without damaging the bearings. Others, referred to as "crowns," are easily removable, allowing you to clean your bearings more effectively.

When cleaning your bearings, it is not always necessary to remove the ball retainers. Simply removing the metal shields or rubber seals will suffice. Keep in mind that if you choose to remove the ball retainers as well, you should do so carefully to avoid dislodging and losing the balls.

Spacers and Speed Rings

Spacers and Speed Rings are essential accessories for the performance and longevity of skateboard bearings. Understanding their function and the importance of proper selection can significantly impact your ride's performance and safety.

Spacers

Skateboard Bearings Spacers

Spacers are small metal cylinders that are placed between two bearings on the truck axle. Spacers serve to protect the bearings and the wheel core from potential damage, especially when the axle nut is overtightened. Additionally, spacers keep the bearings aligned and parallel to each other, which is particularly important when using softer skateboard wheels. Generally, using spacers is crucial to maintaining the condition of your bearings and ensuring a smoother and safer riding experience.

Speed Rings

Skateboard Bearings Speed Rings

Speed rings are small washers placed between the bearing and the hanger or the axle nut of the skateboard. Their primary function is to reduce friction between the bearings and the axle, allowing the wheels to spin more smoothly and freely. Essentially, speed rings help prevent the bearings from pressing against the hanger or axle nut during wheel rotation.

Speed rings are generally included with skateboard trucks, but they can be replaced if necessary.

It is recommended to always use speed rings and spacers to protect your bearings, keep the wheels properly aligned, and allow them to spin at their best performance.

Most of the bearings you purchase from our online store come with spacers already included in the package. Additionally, some sets also include replacement speed rings. You can also purchase skateboard bearings with built-in spacers, such as "Race REDS" from Bones Bearings or "Hoodoo" from Mindless, offering a practical and convenient solution for your setup. You’ll find all the necessary information in the product descriptions or technical sheets.

Skateboard Bearing Lubricants: An Important Choice

Skateboard bearings can come pre-lubricated with two types of lubricants: oil or grease. Each has its advantages and disadvantages, and it's important to understand the differences to make the right choice.

Oil: This is the most common lubricant and typically the faster of the two. Oil provides good performance but tends to leak out of the bearing shields. Beginners often prefer oiled bearings because they like to test the bearing’s spin by flicking it with their hand. While this can feel satisfying and give the impression that your skateboard will be fast and smooth, it’s essential to remember that spinning a bearing by hand is not a real test of speed, as it doesn’t account for the actual weight the bearing will carry.

Grease: Grease is the second most common type of lubricant and is significantly more durable than oil. Grease tends to stay inside the bearing better than oil, increasing its lifespan. However, grease offers more resistance than oil, which typically results in a slower spin when the bearing is flicked by hand. As mentioned earlier, this type of test is not particularly useful in skateboarding, as it doesn’t reflect real-world conditions.

It’s common to see, especially in our store, beginner skaters pick up a skateboard and spin the wheels by hand to gauge the bearing’s speed and smoothness. Spinning the wheel by hand and timing how long it takes to stop is a myth! Bearing speed depends on their cleanliness, lubrication, and proper alignment within the wheel core.

Skateboard Bearing Lubricants

So, which type of lubricant should you choose? It depends on your personal preferences and the type of skating you do. If you’re looking for immediate speed and performance, oil might be the better option. If you want more durability and resistance, grease could be the right choice. Remember, the key to getting the best performance out of your skateboard bearings lies in regular maintenance and attention to detail.

How to Clean and Lubricate Skateboard Bearings

To clean skateboard bearings, you need to remove them from the wheel and take off the shields. Next, place the bearings in a suitable container or a dedicated cleaning container, such as the Bones Bearing Cleaner or the Bronson Bearing Cleaner Unit. At this point, clean the bearings with a degreasing agent like brake cleaner or acetone. Once thoroughly cleaned, dry the bearings and lubricate them. Finally, reattach the shields and reinstall the bearings into the wheel.

For lubricating bearings, as discussed earlier, you have two options: grease or oil. To lubricate bearings with grease, apply a small amount to each side of the bearing. Grease is resistant to water and dirt but increases friction, which can reduce the bearing's speed. On the other hand, to lubricate bearings with oil, use a specific bearing oil (e.g., Bones Speed Cream). Oil makes bearings faster by reducing friction but requires more frequent maintenance as it needs to be reapplied often. In either case, it is crucial to avoid leaving bearings without lubrication, as this can cause them to break or seize up. Additionally, avoid exposing bearings to water, as it can wash away the lubricant and lead to irreparable damage.

How to Install Skateboard Bearings

The installation of skateboard bearings is a relatively simple process but requires some attention and precision.

To install bearings, start by placing a bearing onto the truck axle and then press the wheel onto the bearing until it slides into the wheel. Next, remove the wheel from the axle and position the second bearing on the other side of the axle. You can insert a spacer between the bearings to prevent them from being compressed too much during use.

Then, flip the wheel and press it onto the second bearing, as done earlier, until the bearing is seated properly inside the wheel. Finally, place the axle nut onto the threaded part of the axle, after adding the speed ring, and tighten it adequately. It is important not to over-tighten the axle nut, as this could prevent the wheel from spinning freely and damage the bearings.

Extending the Life of Your Skateboard Bearings

To protect your skateboard bearings and ensure they last as long as possible, there are a few important steps you can take. First, avoid skating in the rain, on wet surfaces, or in humid conditions. Water can cause rust and compromise their durability and functionality. Do not leave your skateboard outside overnight or in adverse weather conditions; it is essential to keep your bearings clean and well-lubricated. Regularly clean them with a dry cloth and apply specific bearing lubricant to maintain smooth and efficient movement. Additionally, you can protect them by using spacers and speedrings, which reduce friction on the bearings and protect them from impacts and excessive pressure. Finally, choose high-quality bearings made from rust-resistant and corrosion-resistant materials. By following these simple tips, your bearings will last longer and provide you with optimal performance on your skateboard.

Frequently Asked Questions About Skateboard Bearings

Do I need to lubricate my new bearings?

Absolutely not! All bearings you purchase from our skate shop come pre-lubricated. There’s no need to add extra lubricant—you can start skating right away without any worries!

Are skateboard and longboard bearings the same?

Yes, in almost all cases, skateboards and longboards can use the same bearings. They are also compatible with cruiser boards and surfskates.

What type of bearings does a skateboard use?

A skateboard, as well as most roller skates or inline skates, uses bearings of size 608. These bearings measure 22 mm in outer diameter, 7 mm in width, and 8 mm in inner diameter/axle size.

How many bearings does a skateboard need?

Each skateboard wheel requires 2 bearings, so you’ll need 8 bearings for 4 wheels. Bearings are almost always sold in packs of 8, so you only need to buy 1 pack for a skateboard.

Are skateboard bearings the same as roller skate bearings?

Usually, yes, but there are some exceptions. It’s always a good idea to check if your bearing shields have the number "608" stamped on them. The "608" code is the standard identifier for skateboard bearing sizes.

When it comes to bearing spacers, the situation can get a bit more complicated. While skateboards use only one size of spacer, roller skates may require spacers of varying sizes.

Do skateboard bearings work for freestyle scooters?

Generally, skateboard bearings fit perfectly with freestyle scooter wheels. However, it’s always a good practice to check with your scooter’s manufacturer to be sure. Standard bearings are usually size 608. Note that freestyle scooters have only two wheels, unlike a skateboard’s four, so you’ll need only 4 bearings. Typically, freestyle scooter bearing packs contain 4 bearings instead of 8, like those for skateboards. If you’re looking for bearings for your freestyle scooter, check out our dedicated section: Freestyle Scooter Bearings.

Are "Swiss" bearings really made in Switzerland?

Not necessarily. The term "Swiss" refers to bearings made using Swiss machining techniques, rather than their place of manufacture. While many companies producing Swiss bearings do manufacture in Switzerland, this is not always the case. Switzerland is globally renowned for its precision craftsmanship, particularly in watchmaking and other high-precision components like bearings. Swiss bearings are generally considered high quality and are often more expensive. Purchasing Swiss bearings from reputable brands like Bones Swiss will ensure you receive a high-quality product.

Do I need bearing spacers?

In short, no, they’re not strictly necessary, but they can greatly improve performance. You can skate without spacers, but if you want to maximize your bearings’ efficiency and keep them parallel, using spacers is highly recommended. Spacers help prevent less precise urethane wheels from negatively affecting bearing rotation. If you want the best performance from your bearings, consider using spacers.

Will new bearings make my skateboard faster?

The answer depends on the quality and condition of your current bearings. If you’re still using the stock bearings from a preassembled skateboard, upgrading to higher-quality bearings could result in significantly better speed and performance. However, if you recently purchased a high-quality skateboard with good bearings and have only used it briefly, switching to new bearings may not result in a noticeable speed increase.

Other reasons to consider buying new bearings include preferring grease-lubricated bearings over oil-lubricated ones, needing more effective shields, or wanting bearings with integrated spacers. While increased speed might be a benefit, there are other factors to consider when choosing new bearings for your skateboard.

How long do skateboard bearings last?

The lifespan of skateboard bearings varies depending on usage. Typically, a regularly used bearing can last between 3 to 6 months and 3–5 years, depending on intensity. For trick or freestyle skateboards, bearings are often the second most replaced component after the deck, with an average lifespan of about 6–9 months. Bearings for longboards or cruisers can last for years, provided they are kept clean and dry.

For downhill or racing bearings, their lifespan is usually around 6 months, especially if they undergo intense sliding and lateral loads. Since ball bearings are not designed to handle heavy lateral forces, regular replacement is key to maintaining optimal performance.

What are "integrated" bearings?

Integrated bearings are specially designed for skateboards, where the spacers and speed rings are built into the inner race. This means you can install the bearings into the wheels without worrying about adding separate spacers. They are a convenient option for simplifying assembly and ensuring proper alignment of components within the wheel.

Are skateboard bearings from Amazon good?

Amazon offers a wide selection of skateboard bearings, including high-quality brands like Bones and Bronson, just like any other retailer. However, it’s important to be cautious about counterfeits and low-quality brands that may be available on the platform.

When purchasing bearings from a reputable brand on Amazon, such as Bones or Bronson, we recommend ensuring the seller is an authorized dealer to guarantee product authenticity. This will help you avoid buying counterfeit bearings that might not deliver the performance and quality you expect.

For peace of mind and to ensure you get genuine, high-quality bearings, it’s always best to buy from a specialized skate shop like ours, where you can receive expert advice and access to original products.
