ABSTRACT:
The disclosure concerns an anti-friction bearing with a specially formed ulder on its bushing. The bearing includes a shaft with two axially spaced raceways formed in it. Two outer races are associated with the respective raceways. A plurality of ball bearing elements are supported within the raceways. There are cages for guiding the balls in the races. The bushing is positioned between the two outer races. When the shaft is held vertically and the ball bearing elements are to be loaded in the top raceway, the shaft is tilted eccentrically of the outer race at the top to provide an enlarged crescent-shaped space between the inner raceway and the outer race to receive the balls. But, the balls fall down from that space. The bushing has a shoulder on one end which extends beneath the top outer race and near to the balls at that race. The shoulder is generally crescent-shaped and extends about 180.degree. around the bushing. The shoulder is shaped and dimensioned such that it supports the balls in the crescent-shaped space and prevents them from falling down as they are being loaded.
