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.

A taper roller bearing comprising:
- an inner ring and an outer ring defining at least one tapered raceway, the tapered raceway having a small diameter portion and a large diameter portion;
- tapered rollers conveyed in a bearing space defined in the tapered raceway between the inner and outer rings;
- a cage arranged for spacing the rollers;
- and
- a grease retainer connected to one of the inner and outer rings, wherein the grease retainer is connected to the outer ring adjacent a portion of the inner ring having the small diameter portion of the raceway.
A grease retainer for taper roller bearings arranged in a bearing space, comprising:
- a ringshaped channel defining an inner space in which grease can be accommodated;
- and
- apertures formed in the channel for communicating the inner space with the bearing space,
- wherein the channel has two generally parallel flanges extending radially inwardly from a bottom of the channel, the flanges being provided with the apertures, and the apertures in the flanges have at least one of varying mutual distances and variable dimensions.
A roller bearing comprising:
- at least one set of roller bearings disposed in a bearing space between an inner ring and an outer ring;
- and
- a grease retainer disposed adjacent the roller bearings, the grease retainer comprising:
- a ringshaped channel defining an inner space in which grease can be accommodated,
- apertures formed in the channel for communicating to the inner space with the bearing space, and
- at least one pipe stub extending radially away from the channel into a corresponding hole in the outer ring.
