Double direction thrust bearings

Thrust ball bearing elements are separable so that mounting is simple to achieve. Single direction thrust ball bearings consist of a shaft washer, a housing washer and a ball & cage thrust assembly. Double direction thrust ball bearings consist of the same elements but have two housing washers and two ball & cage thrust assemblies.

Single direction thrust ball bearings can accommodate axial loads in one direction, hence double direction can accommodate axial loads acting in both directions, neither must be subjected to any kind of radial load.

Both single and double direction thrust ball bearings are available with either a flat seating surface on the housing washers or with a sphered seating surface. Bearings with sphered housing washers can be used together with sphered seating washers to allow for misalignment between the housing and shaft.
