Abstract
A bearing composed of an inner race, two outer races concentric therewith and spaced axially from each other to leave a gap between them. Sets of ball bearings are located between the inner race and each of the two outer races. The outer races are provided with shoulders projecting axially toward one another and the whole is secured by a band wrapped circumferentially around the shoulders. Preferably, the band is thinner than the outer races so that part of the gap remains. The band is somewhat longer than the circumference and the ends are turned radially outwardly and fastened together. In a particularly improved form of the device, frames are located in the gap and are releasably fastened to one another. The width of the gap is larger than the thickness of the frames, so that there is a certain amount of play in the bearing. This provides a self-aligning feature.
