A retainerless angular contact antifriction bearing apparatus including an inner race member having a spheroidal inner race surface, an outer race member including a pair of convex outer race surfaces opposing the inner race surface, and a plurality of rollers arranged in axially oppositely inclined

A retainerless angular contact antifriction bearing apparatus including an inner race member having a spheroidal inner race surface, an outer race member including a pair of convex outer race surfaces opposing the inner race surface, and a plurality of rollers arranged in axially oppositely inclined rows. Each roller includes a concave longitudinal profile having a radius of curvature greater than the radius of curvature of each of the spheroidal inner race surface and the associated convex outer race surface. The radial internal clearance between the roller and the race surfaces is no more than 0.002 inches.
