Unidirectional thrust ball bearings can withstand axial loads in a single direction. They cannot withstand any radial loads. The parts are separable for easy mounting and dismounting as well as maintenance and inspection. Most parts are interchangeable. The bore of the collar is ground to provide an interference fit with the shaft.
