Abstract
A movable member is made from a relatively hard material and is provided with a first surface. A bearing liner is attached to the first surface and is provided with relatively thin, hard and incompressible characteristics. A stationary member made from a harder material than the movable member is provided with a bearing surface which is polished and which abuts the bearing liner. Means retain the movable and stationary members in an optimal bearing relationship. The movable and stationary members may be annular and may have a nested relationship so that the bearing surfaces are annular and the movable member is rotary. The retaining means may include a pair of stationary sleeves made from a similar material to the movable member and abutting each other at an intermediate position along the axial lengths of the bearing surfaces. Each of the sleeves may have a flange abutting axial extremities of the movable and stationary members. A pair of additional bearing liners may be respectively attached to the sleeve flanges at positions abutting the axial extremities of the movable and stationary members. Each of the additional bearing liners may be relatively thin, hard and incompressible. 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.
