SKF cylindrical roller thrust bearings are designed to accommodate heavy axial loads and impact loads. They must not be subjected to any radial load. The bearings are very stiff and require little axial space.

Bearing features

Separable design
Shaft washer, housing washer, cylindrical roller and cage thrust assembly can be mounted separately.Extended bearing service life

To prevent stress peaks, the roller ends are relieved slightly to modify the line contact between the raceway and rollers.consist of a radial needle roller bearing and a cylindrical roller thrust bearingThe cylindrical roller and cage thrust assembly is identical to the 811 series.are supplied without an inner ringcan be combined with an inner ring , where the shaft cannot be hardened and ground must be ordered separately)can accommodate axial loads in one directioncan locate the shaft in one direction onlcan be mounted back-to-back  for short shafts and where changes in length due to thermal expansion are relatively minorFor these types of arrangements, SKF recommends preloading the thrust ball bearings with Belleville washers (cup springs). This elastic preload helps to prevent the balls from skidding if one of the thrust bearings becomes unloaded. Preload also improves performance of the thrust ball bearings while reducing noise levels.
