ABSTRACT:
A sliding thrust bearing has one bearing surface separated into a plurality of regions, each of which has a slot extending radially from the circumferential edge thereof. A plurality of grooves extends from each of the opposite sides of the slot, the grooves extending from opposite sides of the slot being inclined in opposite directions with respect to the circumferential direction of the bearing surface. A further bearing surface engages the grooved surface, whereby pressure of a lubricant builds up in the groove to one side of the slot for one direction of relative rotation of the bearing surfaces, and pressure of the lubricant builds up in a groove to the other side of the slot for the opposite direction of relative rotation of the bearing surfaces. The bearing surfaces may be flat or curved.
