Abstract
A bearing unit, for supporting a pinion shaft having at one side a pinion head, includes a taper roller bearing and an angular ball bearing, the bearings having a common outer race ring and separate inner race rings. The inner race rings are spaced apart a distance along the pinion shaft, and the taper roller bearing has a contact angle α from 15° to 20° for absorbing mainly the radial force component of the tooth force at the pinion head, and the one-row angular ball bearing has a contact angle β of between 35° and 45° for absorbing mainly the axial force coming from the gear mesh and that induced by the taper roller bearing.
