A skateboard is this unique make up of components that all fit perfectly together giving you the best possible experience human life has to offer (well not literally, there's also waves and trails!). Each of these smaller elements that make up a skateboard play their own unique role in turning your set-up into one hell of a ride. Here we are going to tell you a little bit about one of those tiny elements, Skateboard BEARINGS!
Skateboard bearings are the round metal pieces that fit inside the wheels to eliminate friction between the metal inside each of the wheels and the metal truck axle it spins around.
Here's a little insight on the different kinds of bearings out there! The delightful fast & smooth rolling experience gets better as you upgrade to higher quality bearings.
What's the difference between an INR 600 set of bearings vs INR 2,000 set of bearings?
Things you won't actually see that are on the inside, but the performance that you'll feel when you're out there riding!
SIZES- Regardless of wheel size, skateboard bearings are usually a standard size and will fit any skateboard wheel. The most common bearing size is the “608.” Characterized by an 8mm core, a 22mm outer diameter and a 7mm width, these bearings are the industry standard and match up with nearly every skate wheel out there. Of course, there are exceptions to every rule. Rarely, you’ll come across a wheel that is designed for use with a non-standard bearing. There are also mini-bearings that can be used with the standard 608 bearing hub, but they require a sleeve to make them compatible.
ABEC RATINGS- While the ABEC ratings are certainly relevant in some cases, they were designed to evaluate bearings for use in machinery, not skateboard wheels. This scale is simply used to describe the tolerances of a bearing, it does not go into if the bearing is able to spin faster or accelerate faster. ABEC ratings run from 1 to 9 (odd numbers only), with higher numbers meaning more precise tolerances. Unfortunately, the result is that the tolerances measured do not factor in certain forces exclusive to skateboarding. Therefore, while many skate bearing manufacturers will still provide the ABEC ratings for their products, riders should know that they are not end-all.
Bearings use a different material for the balls of the bearing, most common of which is steel and ceramic balls
