ABSTRACT:
A bearing has a self-lubricating liner including sheets of felted polytetrafluoroethylene fibers impregnated with cured phenolic resin having no surface bonding to the fibers. Sheets of fibrous fabric are felted to sheets of felted fibers. Sintered particles are dispersed in the low friction surface of the liner. Liners are formed by air drying resin-impregnated sheets of felted fibrous material. The resin may be cured in a heated platen press before assembly of the bearing. The bearing is assembled by deforming bearing members to form an interference fit between the members and a bearing liner disposed therebetween. Parting compound applied to one of the bearing members prevents bonding of the liner to that member when the liner is baked to cure the resin and bond the liner to the other member.
Bushes and bushings having self-lubricating linings are disclosed. Arbors and mandrels form an interference fit between the linings and bushes and bushings during assembly.
