Roller Bearings - Cylindrical Bearings | AST Bearings

Roller Bearings. Roller & Cylindrical 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 balls as the rolling element). The purpose of cylindrical bearings is to reduce rotational friction and support radial and axial loads.
