A radially movable bearing for a shaft of a gear in a steering system includes a bush or outer ring that is supported in a receiving element of a mount or housing for the gear. In order to create a radially flexible bearing for the shaft of the gear, which movable bearing enables quiet operation for the entire service life of the gear, the outer ring or the bush is held by at least one support element that is inserted in a gap between the receiving element and the outer ring, and that is made of a material with elastomer behavior.
