In this guide I’m going to tell you everything you need to know about what makes that wheel spin on that axel.

We’ll address this in an FAQ format.

What is a bearing?

A bearing is the circular component that fits into your wheel and lets the wheel spin properly and efficiently on the truck’s axel. Included inside the bearing are the balls which help the actual bearing spin. There are between 4-8 balls inside your bearing, depending on what kind you buy.

What are the different sizes?

There is only one universal size for skateboard bearings. The ONLY exception to the size is Element’s Micro Bearings, which are intended to fit in their micro-core wheels, but not many people know about that.
