SKF Thrust ball bearing
Single direction thrust ball bearings
SKF single direction thrust ball bearings consist of a shaft washer, a housing washer and a ball and cage thrust assembly. The bearings are separable so that mounting is simple as the washers and the ball and cage assembly can be mounted separately.
Smaller sizes are available with either a flat seat surface on the housing washer (fig 1) or a sphered seat surface (fig 2). Bearings with a sphered housing washer can be used together with a sphered seat washer (fig 3) to compensate for misalignment between the support surface in the housing and the shaft. Sphered seat washers are available from SKF but must be ordered separately.
Single direction thrust ball bearings, as their name suggests, can accommodate axial loads in one direction and thus locate a shaft axially in one direction. They must not be subjected to any radial load.
