    Apr 01 2014 · • A ball bearing is a type of rolling-element bearing that uses balls to maintain the separation between the moving parts of the bearing. • The purpose of a ball bearing is to reduce rotational friction and support radial and axial loads. It achieves this by using at least two races to contain the balls and transmit the loads through the balls. Jan 23 2018 · The latter is formed by ball mill grinding as two different polymorphs Form A and Form B. The ratio R = Form B / ( Form A Form B ) at milling equilibrium depends on the nature and concentration of the solvent in the milling jar.
