Ball bearings with shields or seals for protection can be lubricated to last for the operating life. Sometimes ball bearings are also called “deep groove ball bearings.” AST Bearings is the leading ball bearing supplier. Ball Bearing Catalog & CAD Library. Precision Ball Bearings versus High-Precision Ball 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 balls as the rolling element). The purpose of a roller bearing is to reduce rotational friction and support radial and axial loads. Compared to ball bearings, roller bearings can support heavy radial loads and limited axial loads (parallel to the shaft). They can operate at moderate to high speeds.


AST Bearings has been supplying ball bearings for more than 40 years. The company maintains an inventory of bushings, rod ends, rollers and subassembly products. It operates accounting, engineering, human resources, information technology, operations and quality departments.
