When searching for a set of bearings, you should pay attention to the quality of the bearing components. Bearings consist of balls, cages and bearing shells. The main difference between quality bearings and cheap imitations is the material of the bearing shell. Bearings made of chromium steel are much cheaper than those made of carbon steel, which lose a lot of running performance under pressure and become much slower.
