Abstract
In order to prevent a reduction in fatigue life and to improve the endurance of a rolling bearing unit which is made up by assembling a pair of angular type ball bearings 4, 5 so as to rotatably support an axial load applied in a substantially constant direction, provided that a radial load F.sub.r and a leftwise axial load F.sub.a are applied to a rotating shaft 2 during running, the contact angle .alpha..sub.1 of the right hand side bearing 4 which takes the axial load F.sub.a is made large, while the contact angle .alpha..sub.2 of the left hand side bearing 5 which takes no axial load is made small, and the left hand side bearing 5 has a slight positive bearing gap during running.
