Timken 21212 Differential Pinion Race - Rear Outer

Timken 21212 Differential Pinion Race

The Timken 21212 differential pinion race is a tapered roller bearing cup for driveline and axle service. It is built for applications that need controlled radial and axial load handling, including differential pinion support in passenger vehicle axle assemblies.

Key Features

• Tapered roller bearing race for differential pinion applications
• Supports radial and axial loads in axle and driveline service
• Engineered for durability in compact bearing spaces
• Timken 21212 is part of a bearing system that should be matched with the correct cone
• Cross-references National 21212 for the same application

Application Details

Compatible With driveline and axle repairs that use a Timken 21212 differential pinion race. This part is commonly selected when servicing differential pinion bearing assemblies on vehicles such as Honda Civic and Toyota Corolla, where precise bearing fit and load control are critical. The Timken 21212 part number is also referenced in interchange listings for 1115029 and BR21212.

What It Helps Address

• Noise from worn differential pinion bearings
• Excessive play in the pinion bearing assembly
• Rough bearing rotation during axle service
• Wear in the bearing cup surface
• Loss of proper load support in the differential

Installation Notes

Replace the inner cone and outer cup together to maintain bearing reliability and service life. Clean the housing thoroughly, inspect the mating surfaces, and verify correct bearing preload during assembly. Use the exact Timken 21212 specification for the axle or differential being serviced.

Quality Assurance

Timken is recognized for tapered roller bearing engineering used in demanding driveline applications. The 21212 race is built to support higher speeds, heavier loads, and long service life when installed as part of the correct bearing set.
