Abstract
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.
