ABSTRACT:
A product lubricated thrust bearing includes an annular bearing disc made from a hard bearing material such as silicon carbide and having a plurality of radial lubrication grooves in at least one of a front and rear face thereof to define a plurality of bearing segments. A polymeric layer is bonded to the rear face of the annular bearing disc, and provision is made for preventing the bearing disc from slipping relative to the bore of the bearing carrier in which the thrust bearing is mounted. The bearing disc may be cracked along the radial lubrication grooves to allow the bearing segments to axially float. A metal disc may also be bonded to the polymeric layer opposite the bearing disc to reinforce the polymeric layer and to facilitate prevention of slippage of the bearing disc.
