ABSTRACT:
A self lubricated and sealed pinion cartridge bearing assembly for use with a gear reduction system which may be used for example for providing rotating shaft support for a pinion shaft of a motor vehicle drive axle. The bearing assembly has a pair of anti-friction bearings having an outer and inner race and a plurality of circumferentially spaced apart rolling elements which roll along inner and outer raceways. A spacer is provided between the bearing inner races, and at least one seal is formed between the inner races and the spacer to circumferentially seal the inner races together. A pair of seals are further provided between the inner and outer races of each bearing at each outboard face to form barriers at the ends of the bearing assembly for retaining lubricating oil within the bearing assembly.
