Senses can be adjusted. This would mean that the Sliding surfaces of the arranged on the end faces of the la ^ er body Pressure bearings no longer wear frleichiaäßic, so it is already has been proposed, in addition to the spherical adjustment to provide elestieche connecting links on the bearing housing, which iia In the sense of a tolerance equalization3 act and in the case of a rerincen misalignment or deflection of the * V / elle the load of the same name over the Usofanp: the thrust bearing should cause.

The aligned condition of the bearing and the parts are thus reduced by the spring-loaded clamping device.
