ABSTRACT:
In an automatic self-aligning roller bearing including an inner race, an outer race and a plurality of rolling bodies disposed between the inner race and outer race, a radius of each of track grooves on the inner race and a radius of track groove on the outer race have a predetermined relationship established therebetween. Thus, a pressure developed on both the inner and outer races is simultaneously uniformly distributed as seen in the axial direction under a condition in proximity of a designed load whereby a running life of both the inner and outer races can be elongated. Consequently, a well balanced roller bearing of the above-mentioned type having a long running life is provided.
