摘要

The tapered roller bearing (1) has a bearing outer ring (2), a bearing inner ring (3) and multiple rolling bodies (4) in the form of tapered rollers (5) with a small diameter roller front (15) and a large diameter roller front (16). The rolling bodies are held in equal distance to each other by cage pockets (17) of a bearing cage (6). The rolling bodies are unwound between bearing rings. Both roller fronts are brought in contact with front sides (22,23) of lubricant elements (18,19) which are fixed at one of the bearing rings in the inner side of the tapered roller bearing.
