How to Choose the Right Skateboard Bearings


Aside from machineries, skateboards also hold bearings in their wheels. They are the metal pieces that fit inside the skateboard wheels to mount it to the axle. The usual size of bearings are 8mm (core), 22mm (outer diameter), and 7mm (width).

There’s a lot of variety of skateboard bearings to choose from. But which one would fit right into your own skateboard? Here’s a small guide on how to choose the right bearing for your skateboard.

ABEC Rating

The ABEC rating is responsible for the quality of skateboard bearings being sold to the market. They check and inspect the quality of materials used and precision in manufacturing the skateboard bearings. The higher the ABEC rating, the more precise and more expensive the bearing will be.

Below are the ABEC ratings users should check when thinking of buying skateboard bearings:

ABEC 1 – The least expensive kind. The quality of the steel is not very high and it is least accurate.

ABEC 3 – Bearings do not usually roll smoothly and quickly.

ABEC 5 – The standard rating for most of skateboard bearings.

ABEC 7 – Very fast and smooth.

ABEC 9+ – Bearings are fast.

Bearing Materials

The bearing material is also an important factor in choosing your skateboard bearings. Aside from looking into its ABEC rating, it is important to conduct research on what kind of bearing would suit your skateboard.


Most skateboard bearings are made out of steel. Steel-made bearings are made for durability and economical purposes. Bearing quality differs from brands. Most skateboarders are fine using steel bearings for their skateboards. The down side for steel bearings is that, they tend to expand because of the friction between the axle and wheel. The heat coming from them tend to expand the bearings and causing it to be ineffective. Screeching is also a problem when you buy a bearing that is made out of poor quality materials.


Ceramic bearings are more expensive than steel bearings. Ceramic bearings produce smooth performance and less friction. It also won’t expand due to the heat of the axle and wheel. Because they are more of quality, the price for ceramic bearings usually goes in a range of $70-$100. But some skaters will tell you that upgrading to ceramic bearings is worth the investment.

Bearing Size

Like what was mentioned above, the standard size for skateboard bearings is 8mm (core), 22mm (outer diameter), and 7mm (width). These is the industry standard. There’s an exception to the rule. There are wheels that are designed to use a non-standard bearing. They may be bigger or smaller than the industry accepted size. It is important to know what are the sizes of the bearings your skateboard uses.
