The oscillating bearing to be described herein uses only the arcuate bearing surfaces necessary to handle an oscillating mechanism rather than the conventional complete 360° radial bearing. One particular use of this new oscillating bearing is with valve train rocker arms used on internal combustion engines.
Briefly described, the oscillating bearing for a stud mount comprises an arcuate inner raceway, an arcuate outer raceway, and an arcuate retainer between said raceways. The raceways and the retainer have aligned openings through which a stud may extend. Arcuate roller pockets are located on each side of the retainer stud opening and spaced from said opening. The roller pockets are long enough in the oscillating direction to receive a plurality of rollers. A plurality of rollers are located in each arcuate roller pocket.
