spherical roller bearing railways bolivia

Roller Bearings. Roller Bearings are a type of rolling-element bearing that uses cylinders (rollers) to maintain the separation between the moving parts of the bearing (as opposed to using ballsas the rolling element). The purpose of a roller bearing is to reduce rotational friction and support radial and axial loads.
