ABSTRACT:
The disclosure concerns a two-row angular-contact ball bearing with axially spaced apart inner races defined on a shaft and outer rings with outer races disposed around the inner races. The outer rings are held apart by a bushing, and a spring inside the bushing presses one outer ring away from the other. At each outer ring is a respective cage for the bearing balls and the cage has a T-shaped cross section with the leg of the T being the prongs between adjacent balls and the cross bar of the T resting on one radial side on a collar defined on the shaft and at the other radial side which is radially outwardly of the collar, on the end of the respective outer ring, and with the cage resting there, the balls are in the inner race. The cage includes elements surrounding the balls and defining pockets and at least some of the sections of the pockets are resilient to expand as the balls are moved over the shaft toward the race and to return to shape after the balls have entered the inner race.
