ABSTRACT:
A self-aligning, self-contained, self-lubricating cartridge bearing assembly including a nonporous bearing member having a central bore sized to receive a rotatable shaft. The bearing member has an aperture extending radially from its central bore to its outer surface to receive a contractor made of fibrous material. The bearing member may be made of die cast aluminum alloy. The bearing member is held in a mounting member by two retainers. An oil-impregnated wicking material surrounds the bearing member and contactor. An oil slinger sized to fit on the rotatable shaft for rotation therewith is positioned adjacent to the bearing member to sling lubricant radially outward. End caps are provided which retain the oil-impregnated wicking material inside the bearing assembly. In some embodiments, the retainers are resilient spring elements which, by their resilience, hold the bearing member in a captive ball and socket configuration. In other embodiments, one of the retainers is a substantially rigid, unitary portion of the mounting member, and the other retainer is substantially rigid, so that the cartridge bearing assembly can withstand heavier loads. In the latter embodiments, the bearing member is press fit between the retainers, which are precisely dimensioned and spaced.
