Bearings Direct supplies insert ball bearings for housing and industrial equipment use. These insert bearings come in a variety of configurations for various duty strength applications.Insert bearings  Insert bearings  are based on sealed deep groove ball bearings in the 62 and 63 series, but have a convex outer ring and in most cases an extended inner ring with a specific locking device, enabling quick and easy mounting onto the shaft.

 Ball bearings consist of a series of round balls in a casing, within an inner and outer ring capable of supporting both radial and axial (thrust) loads.Ball bearings can support moderate radial loads and moderate axial loads (parallel to the shaft). They can operate at high speeds. Ball bearings with shields or seals for protection are usually lubricated to last for the operating life.
