Abstract
A movable member made from a relatively hard material is provided with a first surface. A bearing liner provided with relatively thin, hard and incompressible characteristics is attached to the first surface. A stationary member made from a harder material than the movable member is provided with a polished bearing surface which abuts the bearing liner. Means retain the members in an optimal bearing relationship. The members may be annular and may have a nested relationship. The retaining means may include a pair of stationary sleeves made from a material similar to the movable member and abutting each other at one end. Each of the sleeves may have a flange abutting axial extremities of the movable and stationary members. A pair of additional thin, hard and incompressible bearing liners may be respectively attached to the sleeve flanges at positions abutting the axial extremities of the movable and stationary members. In another embodiment, the stationary member is provided with a flange at one lateral extremity and a single sleeve is provided with a flange at the opposite lateral extremity. The additional bearing liners may be attached to the movable members at positions abutting the flanges.
