Thrust Ball Bearings

Technical Information

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 or a sphered seat surface.
 
Bearings with a sphered housing washer can be used together with a sphered seat washer to compensate for misalignment between the support surface in the housing and the shaft.
 
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.
 
Double Direction Thrust Ball Bearings

SKF double direction thrust ball bearings consist of one shaft washer, two housing washers and two ball and cage thrust assemblies. The bearings are separable so that mounting is simple. The various parts can be mounted separately. The housing washers and ball and cage thrust assemblies are identical to those of the single direction bearings.
 
Smaller bearings are available with either a flat seat surface on the housing washers or with a sphered seat surface.
 
Bearings with sphered housing washers can be used together with sphered seat washers to compensate for misalignment between the housing and shaft. The sphered seat washers are available from SKF, but must be ordered separately.
