Ball Bearings, Brand Name : SKF, FAG, NTN, KOYO & NSK

A ball bearing is a common type of rolling element bearing, ball bearings typically support both axial and radial loads and can tolerate some misalignment of the inner and outer races. Also, balls are relatively easy to make cheaply compared to other kinds of rolling elements. Ball bearings tend to have lower load capacity for their size than other kinds of rolling-element bearings due to the smaller contact area that spherical shapes provide.
