Abstract

1349035 Bearings SWF-SPEZIALFABRIK FUER AUTOZUBEHOER GUSTAV RAU GmbH 22 Oct 1971 [27 Oct 1970] 49181/71 Heading F2A A thrust bearing for a shaft 11 is formed on an adjusting screw 14 which is movable axially relative to the shaft, there being a spring 16 which engages the screw and the housing of the screw, the arrangement being such that the spring urges the screw to turn to reduce the clearance between the shaft and the bearing. The end 13 of the shaft which engages the bearing may be spherical or conical. The spring may be helical with one end 21 engaging in a slot 19 in the end of the screw and the other end 17 located in a securing ring 18 in the housing.
