Single direction thrust ball bearing with sphered housing washer

Single direction thrust ball bearings, with sphered housing washer, can accommodate axial loads in one direction. They must not be subjected to any radial load.

Many of the components are interchangeable. The shaft washers have a ground bore that enables an interference fit. The sphered housing washers can accommodate initial misalignment when configured correctly with a sphered seat washer or a machine component with a sphered surface.

  • Separable design facilitates mounting/dismounting and maintenance inspections
  • Interchangeable components
  • Ground bore of shaft washers enables interference fit
  • Sphered housing washers can accommodate initial misalignment
