Abstract
Abstract An anti-friction ball bearing assembly adapted for mounting on a shaft comprising an outer sleeve and an inner sleeve concentrically fitting within said outer sleeve, the inner sleeve having a number of tracks defining paths for the circulation of balls between said sleeves and said shaft during movement between said shaft and said bearing assembly, the inner surface of the outer sleeve being provided with a number of axially extending channels adapted to receive a plurality of insertable members each having a raceway surface thereon providing bearing support for said balls during the portion of their circulation path in which said balls are in contact with said shaft and said raceway surfaces.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
158 words
An anti-friction ball bearing assembly comprising an outer sleeve and an inner sleeve concentrically fitting within said outer sleeve, said inner sleeve having a central opening for the passage of a shaft therethrough, the inner sleeve having a number of tracks defining paths for the circulation of balls between said sleeves and said shaft during relative movement between said shaft and said bearing assembly, the outer surface of the inner sleeve being polyhedronal in shape, the inner surface of the outer sleeve being provided with a number of guideways, the intersections of the plane portions defining the outer surface of the inner sleeve registering with said guideways, said inner surface of the outer sleeve is further provided with a number of axially extending channels adapted to receive a plurality of insertable members each having a concave raceway surface thereon aligned with said tracks providing a bearing support for said balls while said balls are in their loaded state.
Claim 2
Dependent Claim
