ABSTRACT:
A spherically sliding bearing unit generally includes an inner member having a first spherical surface, an outer member having a second spherical surface located opposite to and spaced apart from the first spherical surface, and a liner fixedly attached to the second spherical surface of the outer member to thereby provide a sliding interface between the liner and the first spherical surface of the inner member. The liner has a two-layer structure including an inner layer comprised of a resin material having a low coefficient of friction and an outer layer comprised of a metal. Preferably, the metal outer layer has an irregular structure, such as radial projections or grooves, such that a physically strong coupling can be provided between the liner and the outer member.
