There are many questions when it comes to skateboarding, such as what kind of board to get, what size to get, what kind of trucks, and what kind of bearings. One question that is often asked is if skateboard bearings are the same as roller skate bearings. Most of the time, the answer is yes!

Skateboard bearings and roller skate bearings are usually the same size, with the standard size being 8mm. This means that in terms of performance, you can use skateboard bearings on rollerblades. However, there may be some exceptions to the general rule. In that case, you need a specific size of bearings to fit your skates.

In this blog post, we will be discussing the similarities and differences between skateboard bearings and roller skate bearings.

Basics of Understanding Bearings

If you’re like most people, you probably don’t think much about the bearings in your life. But if you stop thinking about it, bearings are actually pretty important! Because these tiny components are what allow your skateboard to roll smoothly down the street. Here are some basic things you should know.

General Info

Skateboard bearings are small metal cylinders that are placed between the wheels and the axles of a skateboard. They allow the wheels to rotate smoothly and prevent them from being damaged. Spacers are also placed between the bearings to keep them from being forced into the center of the wheels when the axle nut is tightened.

Parts & Composition

The bearings are the most crucial component of a skateboard, which is made up of several distinct pieces. The wheels can turn because of the bearings. They are made up of a small inner ring, a huge outer ring, and tiny steel balls in between. These balls are kept in a “ball cage,” as the name suggests.

Shields, which are coverings on either side of the rings, keep the bearings from becoming soiled. Skating with shieldless ball bearings that are open or semi-open is another option.

Skating with open or semi-open bearings will make them somewhat faster, but they will also be more prone to contamination. Additionally, a skateboard with exposed bearings generates a little louder sound, which many skaters find appealing.

ABEC Rating: Myth or Fact?

There’s a lot of debate surrounding the ABEC rating system for skateboard bearings. Some people swear by it, while others say it’s a myth. So, what’s the truth? Let’s learn about this matter.

What Is ABEC Rating?

The tolerance for error in the bearing manufacturing process is measured using the ABEC rating method. The tolerance for error decreases as the ABEC rating rises.

Does ABEC Rating Matter for Skateboards?

The short answer is no. The ABEC rating is only relevant for bearings used in industrial applications where high speeds are achieved. For skateboarding, the speeds achieved are relatively low, so the ABEC rating is not relevant.

What Is Skate Tested Bearings?

Skate Tested Bearings are bearings that have been specifically designed to meet the demands of skateboarding. As a result, they are usually more resistant to impact and lateral forces.

Are There Any New Developments in Skateboard Bearings?

Yes, there are always new developments in skateboard bearings. For instance, there are now bearings with parts made out of titanium or extra-hard balls made of tempered ceramic. These special technologies offer a longer lifespan and are naturally also more expensive.

Bearings Specs and Size

Size 608 rollerblade bearings are typical, being 22 mm in diameter, 8 mm in bore, and 7 mm in width. The majority of skateboards and rollerblades should use these. Therefore, you are able to fit normal skateboard bearings into your rollerblades. You might discover the following sizes:

  • Size 627, 22mm in diameter, 7mm in bore, and 7mm in width. Quad skates that are used primarily for aesthetic, speed, and recreational purposes.
  • Size 688 has a 4mm or 5mm width, an 8mm bore, and a 16mm diameter. The wheels of some modern speed skates feature these tiny, lightweight bearings.
  • Size 698 has a 6mm wide, 8mm bore, and 19mm diameter. New skate wheels employ these lightweight bearings as well.

How Are Skateboard Bearings Different from Roller Skate Bearings?

Skateboard bearings and roller skate bearings are actually quite similar. Both types of bearings are designed to reduce friction and allow smooth movement. However, there are a few key differences between the two.


Skateboard bearings are typically made from steel, while roller skate bearings are made from a harder material, such as ceramic. The different materials make each type of bearing better suited for different skating styles. For example, steel bearings are better for street skating, while ceramic bearings are better for speed skating.


Skateboard bearings are designed for speed. They are smaller and made from materials that allow them to spin quickly. Roller skate bearings, on the other hand, are designed for stability. The larger size and different materials make them better suited for slower speeds.


Skateboard bearings are typically more expensive than roller skate bearings. This is due to the different materials used and the higher speed rating.

Why Do Skateboard Bearings Matter?

Skateboard bearings are one of the essential parts of a skateboard, and yet they are often overlooked. Skateboard bearings allow the wheels to rotate freely and smoothly; without them, skating would be a lot harder. Here are some of the reasons why skateboard bearings matter:

Skateboard Bearings Affect Speed and Maneuverability

The bearings on your skateboard affect how fast your board can go and how easily it can turn. So if you are looking for a fast board that can make tight turns, then you need to pay attention to your bearings.

Skateboard Bearings Affect the Lifespan of Your Skateboard

The quality of your bearings will affect how long your skateboard lasts. If you want your skateboard to last for years, then you need to invest in high-quality bearings.

Skateboard Bearings Can Be a Source of Customization

One of the great things about skateboarding is that you can customize your board to suit your own style. Bearings are one of the many ways you can do this. In addition, there are a variety of colors, materials, and sizes to choose from, so you can make your skateboard unique.

Skateboard Bearings Can Be a Source of Problems

Unfortunately, bearings can also be a source of problems. If your bearings are not of good quality, they can break down quickly. This can lead to a loss of speed and maneuverability, and it can also damage your skateboard.

Skateboard Bearings Need to Be Maintained

Like any other part of your skateboard, bearings need to be maintained. This means keeping them clean and lubricated. If you take care of your bearings, they will last longer and perform better.

Skateboard bearings are an important part of a skateboard, and they should not be overlooked. Bearings affect speed, maneuverability, and the lifespan of your skateboard. They can also be a source of customization or problems. Whatever your reason for paying attention to your bearings, make sure you take care of them.

Frequently Asked Questions

1. How often should you clean roller skate bearings?

Roller skate bearings should be cleaned every few weeks to keep them in good condition.

2. How to lubricate skateboard bearings?

There are a few different ways that you can lubricate your skateboard bearings. One way is to use a bearing lube, which is a special type of lubricant made specifically for skateboard bearings. Another way is to use WD-40 or another type of penetrating oil. Finally, you can also use light oil, such as 3-in-1 oil.

3. How often should you replace skateboard bearings?

You should replace your skateboard bearings every few months or as needed.

Final Say

In conclusion, skateboard bearings are similar to roller skate bearings in that they are both made to reduce friction.

However, Skateboard bearings are different from roller skate bearings in that they have a higher tolerance for speed and are more durable. Therefore, Skateboard bearings matter because they help to reduce friction and make the skateboard more durable.
