Everything about bearings

if you want to pick a bearing for you, either go with a brand you trust, or go for the cheapest bearings that we have on Thisissoul.com and just replace them when worn down

How many do i need?
There are 2 bearings for each wheel. So if you have 4 wheels per skate, then you would need 16 bearings to replace them all.

how to taking a bearing out.

ABEC Rating

The short answer: Do not pay attention to the ABEC or wheel hardness metrics 

Skate bearings are kind of all the same nowadays. If you have a skate bearing, The way it functions and wears down has more to do with the material used and the way it is lubricated, then with the ABEC scale.

The ABEC scale is a way to measure the precision of the bearing. It was not however invented for inline skating but for machine equipment and it thus has no relevance for the performance of your bearing in your skate.

 

In general if you buy a  200-250 euro's range skate, then the wheels and bearings are always very good, so do not worry about it
