A roller bearing assembly for supporting a shaft axially and radially in a rack includes a roller bearing with a carrier, a portion of which is supported at the rack with an element with elastomeric properties being interposed between a support for the rack and the portion of the carrier. In order to indicate a roller bearing, which supports the shaft axially and radially, and makes an inclined position of the shaft possible without causing straining of the system of shaft, roller bearing and rack, the element with elastomeric properties, viewed in the tangential (circumferential) direction of the roller bearing, has at least a first region, the stiffness of which is different from that of the remaining tangential (circumferential) region.
