A single row tapered roller bearing enables an axle shaft to rotate in an axle housing and further confines the shaft axially with respect to the housing. The bearing includes a cup that is fitted into the housing and a cone that is fitted around a bearing seat on the shaft and also tapered rollers located between raceways on the cup and cone. Radial loads and thrust loads in one axial direction are transferred to the rollers at the raceways. Thrust loads in the other axial direction are transferred to the rollers at a confining surface on the cup at the large ends of the rollers and at another confining surface on a backing collar located at the small ends of the rollers. The backing collar fits over the bearing seat on the shaft with an interference fit and captures the cone on the bearing seat. The bearing also has a cage provided with pockets which receive the rollers, and the cage at its small ends has tabs which project behind a rib on the backing collar and interlock the cage and the collar, so that prior to installation on the shaft the backing collar remains with the cup, cone and rollers. The cup carries a speed sensor which monitors rotation of an excitor ring on the cone.
