81220 Cylindrical Roller Thrust Bearing
Cylindrical roller thrust bearings are designed to accommodate heavy axial loads and shock loads. They must not be subjected to any radial load. The ends of the rollers are relieved slightly to modify the line contact between the raceways and rollers. This prevents stress peaksat the roller ends to extend bearing service life.
Cylindrical roller thrust bearings are very stiff and require little axial space. They are separable, that means that shaft washer, housing washer, and cylindrical roller and cage thrust assembly can be mounted separately.
Cylindrical roller thrust bearings are manufactured with one or two rows of rollers . Bearings in the 811 and 812 series are mainly used in applications where thrust ball bearings do not have sufficient load carrying capacity.
Single direction cylindrical roller thrust bearings are available as single direction bearings and can accommodate axial loads in one direction only.
Double direction cylindrical roller thrust bearings can accommodate axial loads in bothdirections. They can be created by combining two cylindrical roller and cage thrust assemblies and two bearing washers with an intermediate washer. Depending on the design, an intermediate washer can be shaft or housing centred.
