SKF Cylindrical roller thrust bearing 81238 M

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. Bearings in the 811 and 812 series with one row of rollers are mainly used in applications where thrust ball bearings do not have sufficient load carrying capacity. Depending on their series and size, cylindrical roller thrust bearings are fitted with A Glass fibre reinforced PA66 cage (suffix TN) or a machined brass cage (suffix M).

Bearing features:

Separable design
Shaft washer (WS), housing washer (GS), cylindrical roller and cage thrust assembly (K) 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.
