Abstract
Tapered roller bearings are disclosed. The bearing may include an inner ring defining an inner raceway and an outer ring defining an outer raceway. A plurality of tapered rollers may be disposed between the inner and outer rings and a cage may be configured to retain the plurality of tapered rollers. The inner ring may include a rib at a first axial end configured to retain a larger diameter end of the tapered rollers but not have a rib at a second axial end that is proximate a smaller diameter end of the tapered rollers. A gap may be defined between the cage and the inner ring at the second axial end, the gap configured to control a lubricant flow to the plurality of tapered rollers.
