Abstract
A bearing assembly for supporting a shaft in a housing includes two single row tapered roller bearings mounted in axial alignment, yet in opposition. The first bearing is conventional, having the usual cup, cone and complement of tapered rollers. The second bearing has a conventional cone and complement of rollers which may be the same as their counterparts in the first bearing. However, the cup of the second bearing further has an integral axial extension which projects toward and abuts the back face of the cup for the first bearing. The two cones are separated by a spacer and are clamped between two radial abutments on the shaft, whereas the cup of the second bearing is clamped with respect to the housing such that it is incapable of shifting relative to the housing. This secures the entire bearing assembly in the housing.
