Abstract

1355949 Bearings DEFENCE SECRETARY OF STATE FOR 11 June 1971 [7 May 1970] 33661/73 Divided out of 1348629 Heading F2A A lubricated rolling element bearing comprises a plurality of grooves in at least the inner surface of the cage 13 (Fig. 2) and inclined at an acute angle to the direction of normal relative rotation between the cage and inner race, said rotation causing lubricant to flow in said grooves and hence to be directed inwardly toward the points or lines of contact between the rolling elements and the inner race. The grooves may be formed on extensions 16 (Fig. 5) of the cage located between the rolling elements adjacent to the inner race track.
