Abstract
A bearing comprises an inner race defining an inner track, an outer race defining an outer track, and a compound roller assembly interconnecting the inner and outer races for relative rotation between the inner and outer races. The compound roller assembly includes a plurality of first rollers and a plurality of second rollers. The first and second rollers respectively contact the inner track of the inner race and the outer track of the outer race for rolling contact therewith. Each of the first rollers contacts at least one of the second rollers such that the first and second rollers rotate in opposite directions during relative rotation between the inner and outer races.
