Using very precise tolerance and with the use of grease instead of thin oil, the bearing does not need a break-in period. 

Providing a smooth and fast roll, this bearing uses a  rubber seal that is perfect to keep dirt out.

The bearing has a teflon cage with stainless metal bearing balls in them.

The Symetrics bearings are A9 grade bearings and perfect for inlineskating.
