Overview – BEARING ROLLER 201123
201123 is the roller bearing used on CUMMINS engines and drivelines to carry radial load on rotating shafts with low friction. We can supply this bearing as well as the related family numbers listed below, in stock or available on order – welcome to enquire by part number.
Parts Characteristics
The bearing is built to the original bore, outside diameter and width, with the roller complement matched to the CUMMINS shaft journal. The inner and outer rings are ground to the original race geometry so the bearing carries load evenly. The cage keeps the rollers spaced correctly for the rated speed and load. As an OEM-spec bearing, it presses into the original housing without machining.

When replacing, remove the old bearing with a suitable puller, clean the housing bore and shaft journal, and fit the new bearing with even pressure on the correct ring.
