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.
