Bidirectional thrust ball bearings

Bidirectional thrust ball bearings can withstand axial loads in both directions, but they cannot withstand any radial loads. Their separable elements facilitate mounting/dismounting and maintenance checks, and most elements are interchangeable. The bore of the collar is ground to achieve an interference fit with the shaft.

  • Separable design facilitates mounting and dismounting as well as maintenance inspections.
  • Replaceable components
  • The bore of the collar is ground to provide an interference fit with the shaft.
