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.
