SKF thrust ball bearings are designed to accommodate axial loads only and must not be subjected to any radial load. The separable components of SKF thrust ball bearings are interchangeable (This facilitates mounting and dismounting, and maintenance inspections. Shaft washers have a ground bore to enable an interference fit. The bore of the housing washer is turned and always larger than the shaft washer bore. Single direction thrust ball bearings consist of a shaft washer, a housing washer and a ball and cage assembly. They can accommodate axial loads and locate a shaft axially, in one direction only.
