Roller Thrust Bearings By Nrb Bearings Ltd.

The rolling elements of a thrust bearing are retained and guided in the radial pockets within the cage (1). The latter is itself retained in relation to the plate (2) by means of a steel ring (3). This assembly of parts is easy to handle and install and provides a high load capacity whilst occupying minimal space.

The design of NRB thrust bearing serves to reduce to a minimum the friction between the rolling elements and the cage that guides them. Given correct installation and adequate oil lubrication, the co-efficient of friction will be between 0.003 and 0.004 for needle thrust bearings and between 0.004 and 0.005 for roller thrust bearings.
