Abstract

A step bearing for a shaft of a spinning rotor includes a freely rotatable supporting ball and a thrust bearing, against which the supporting ball is disposed. The supporting ball, the thrust bearing and a front-sided supporting surface of the shaft are placed in a housing for lubricating grease. The housing is arranged in a cartridge, which, together with the supporting ball, can be disassembled. It is hereby possible to renew the supply of lubricating grease by simply exchanging the cartridge.
