Abstract
A compound bearing having a shell defining a cylindrical bore in which is installed the bearing inner member, a bearing ring of ultra high molecular weight polymer being disposed within the shell cylindrical bore between the bore surface and the peripheral surface of the inner member. The polymer bearing ring is extruded in strips cut to length and wrapped around the inner member with abutting ends prior to inserting the ring within the shell bore. In structures wherein the inner member is a spherical member or ball, the strip is extruded with a cylindrical groove on at least one surface such as to form a concave spherical surface when wrapped around the spherical peripheral surface of the inner member.
