Peculiarities of designing reinforced thermosetting plastic for a friction unit bearing

Usage of polymer composite materials in heavy-duty friction bearings helps solve many technical and economical problems. Scarce copper alloys are saved, cost of a friction unit is reduced, at the same time its wear resistance is increased. Thus operation life of machines is increased and spares consumption is reduced. Extensive bench and operation testing of friction bearings in various friction units confirmed correctness and practicability of using polymer composite materials instead of other antifriction materials. Long-term experience enabled the authors to develop an algorithm for designing a reinforced thermosetting plastic for a friction bearing.
