ABSTRACT OF THE DISCLOSURE A sealed compound bearing consisting of an outer and an inner member movable relative to each other and between which are disposed load carrying annular members. The load carrying annular members comprise a pair of elasto- meric rings held between the outer and inner members under compression, and a metallic ring insert disposed between and separating the two elastomeric rings. A narrow clear- ance is provided between the peripheral surface of the metallic ring insert and the inner surface of the bearing outer member, and between the metallic ring inner surface and the inner member peripheral surface. Normal loads are taken and absorbed by the elastomeric rings, while overloads and shock loads are taken by the metallic ring insert. A non-clearance thin metallic sealing ring is disposed between each elastomeric ring and a corresponding side surface of the ring insert, pre- venting the material of the elastomeric ring from creeping into the spaces resulting from the clearance existing be- tween the ring insert and the outer and inner bearing members, and preventing introduction of dirt and contaminants into the clearance spaces.
