A taper roller bearing comprises an inner ring and an outer ring having tapered raceways, a bearing space in which tapered rollers are arranged, as well as a cage for mutually spacing the rollers. A grease retainer is connected to the outer ring. The grease retainer is situated next to the inner ring part having the smallest raceway diameter. The retainer comprises a ring-shaped channel in the inner space of which grease can be accommodated. The channel has apertures for communicating the channel inner space with the bearing space.

A hub unit comprises a wheel bearing and a driving axle stub which is situated in a correspondingly shaped, concentric opening in the rotatable ring of the wheel bearing, and in the direction of rotation interacts by unround shapes with the ring which driving axle stub has an axle end projecting from the opening in the ring. The axle end interacts with the inner periphery of a cup spring whose outer periphery is supported under pre-tension on the ring. The cup spring is accommodated in a peripheral groove provided in the axle end.
