ABSTRACT:
A bearing assembly designed to preclude the escape of lubrication through bushings within which elongated shafts are rotated at high speeds. The bearing assembly is comprised of a bearing member of split-ring form which is made of a readily moldable self-lubricating material having a pressure velocity value at least equal to 1800 at 100 feet per minute surface speed, and is L-shaped in cross-sectional configuration. It includes an elastomeric sealing ring mounted in supporting relation to the sealing portion of the L-shaped bearing member which is compressed therewith within a groove provided for that purpose at the outer end of the bushing. The sealing ring maintains the bearing member in close-fitting, sealing relation to the sealing surface surrounding the shaft and is insulated by the bearing member from the sealing surface having rapid relative movement and from associated parts to thereby obviate the normally attendant destructive effects of high speed rotation upon such a ring.
