• This type of bearing comprises washer-shaped rings with raceway groove and ball and cage assembly.

• Washers to be mounted on shafts are called shaft washers ( or inner rings ); and, washers to be mounted into housings are housing washers ( or outer rings ).
  Central washers of double direction bearings are mounted on the shafts.

• Single direction bearings accommodate axial load in one direction, and double direction bearings accommodate axial load in both direction.
  (Both of these bearings cannot accommodate radial loads.)

• Since bearings with a spherical back face are self aligning, it helps to compensate for mounting errors.

Recommended cages

Pressed steel cage, copper alloy or phenolic resin machined cage, synthetic resin molded cage.

Main applications
