Abstract: A linear bearing is made with races molded in place in a plastic shell. An inner ball cage is assembled by sliding the cage into the shell. Open ends of the ball receiving guides in the cage slide along the inward extending races. The cage and ball guide are completed with a cap fitted in an opposite end of the shell.

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.

Abstract: A bearing assembly having an inner race member movably mounted in an outer race member, the inner surface of the outer member being a concave spherical surface and the outer surface of the inner member being a complementary convex spherical surface. The outer race member is received within an aperture formed in the head of a shank assembly. The bearing surfaces are formed of zinc-plated metal having a chromium skin layer and a chromium enriched subsurface layer. The chromium skin layer is about 40 microns thick.

Abstract: A spherical bearing assembly has a metal inner race member and an outer race member. The inner surface of the outer race member is a concave spherical surface and the outer surface of the inner member is a complementary convex spherical surface. The outer member includes an annular recess the base of which is threaded. The recess is adapted to threadably receive a first yieldable plastic annular ring whose outer surface is threaded with threads complementary to the threads on the base of the recess. A second formable and yieldable annular ring is also received in the recess in a side-by-side relationship with the first annular ring. The inner surface of the first and second annular rings provide approximately one-half of the concave spherical surface of the outer race member. The first annular ring operationally captures the second annular ring and the inner race member within the outer race member.

Abstract: A spherical bearing includes an outer member having a hole extending from side to side, the surface of the hole being concave and spherical so that the outer member has constricted portions at each side. The outer member also has a walled keyway extending downward from the hole and extending axially from side to side of the outer member substantially perpendicular to the sides of the outer member; a walled key in the keyway is co-extensive with the keyway. The key also has a concave and spherical top surface corresponding to the surface of the hole so that the key has shoulder portions corresponding to the constricted portions of the outer member. A partially spherical inner member has flat sides, the inner member being held in the outer member by impingement of the spherical surface of the inner member against the constricted portions of the outer member and the key being held in the outer member by impingement of the shoulder portions of the key against the spherical surface of the inner member.
