Skateboard Bearings

Skateboard Bearings mount the wheels onto the axel. They can have a dramatic effect on your wheels. Each skateboard wheel is mounted on its axle via two ball bearings.

Most Skateboard Bearings are the industrial standard "608" size, with a bore of 8 mm, an outer diameter of 22 mm, and a width of 7 mm. These are usually made of steel, though silicon nitride, a high-tech ceramic, is sometimes used. Many skateboard bearings are graded according to the ABEC scale.

 The scale starts with ABEC1 as the lowest, and progresses to 3, 5, 7, and 9. It is a common misconception that higher numbers are better for skateboarding, as the ABEC rating only measures tolerances, which do not necessarily apply to skateboards. The ABEC rating does not determine how fast or how durable a bearing used for skateboarding will be.
