The combination comprising a housing, a shaft journal having a gear wheel at one end, and a bearing assembly rotatably supporting the shaft journal in a cylindrical seat in the housing. The assembly includes a one-piece outer ring having threads on its outer periphery cooperating with threads in the cylindrical seat. The outer ring is rotatable to permit axial adjusting movement of the bearing assembly relative to the housing. The bearing includes two rows of rolling bodies in the annular space between the rings spaced closely relative to one another and an inner race ring on the shaft journal for each of the rows of rolling bodies. One of the rows comprises rollers having axes inclined at an angle to the bearing axis disposed adjacent the gear wheel and the other row of rolling bodies comprises balls which roll against raceways in the ring to provide angular contact disposed at the opposite end of the shaft journal. A locking member engages the threads of the outer ring to permit axial adjustment thereof relative to the housing and abutts the housing to lock the outer ring in a predetermined axial position in the housing.
