  • Differential pinion bearing assembly
    Patent number: 11193573
    Abstract: A differential includes a unitized double row angular contact ball bearing supporting a pinion stub shaft. The bearing includes two inner rings which are slightly separated before assembly. As the stub shaft is inserted into the bearing, one of the inner rings is pushed against a land such as the back of the pinion gear. Pushing the inner rings together ensures a suitable pre-load. The inner rings have an interference fit with the stub shaft such that friction maintains the pre-load without a nut. The bearing and shaft are then inserted between halves of a two-piece case.
