Cylindrical Roller Thrust Bearings are simple in form and design and are produced in single row and double row designs. The bearings in the 811 and 812 series are mainly used where thrust ball bearings have insufficient load carrying capacity.
With the same centre as the bearing, the spherically formed outer ring raceway can make self-alignment. Their rolling elements linearly come into contact with the raceways of inner ring and outer ring. The Spherical Roller Bearings can take great radial load.
