Timken 55175C Differential Pinion Bearing - Rear, Rear Inner or Rear Outer

Timken 55175C Differential Pinion Bearing

The Timken 55175C differential pinion bearing is a tapered roller bearing component for driveline and axle service. It is built for applications that need to manage radial and axial loads while maintaining compact packaging and dependable bearing support.

Key Features

• Tapered roller bearing design for differential pinion service
• Supports both radial and axial loads
• Engineered for durability in a compact space
• Timken bearing technology for driveline and axle applications
• Part number 55175C for accurate ordering and replacement

Application Details

Compatible With differential pinion bearing applications that specify Timken 55175C. This part cross-references Timken (e.g., 55175C) for the same application. When servicing a differential, replace the inner cone and outer cup together to help restore proper bearing function and long-term reliability. Timken 55175C is a practical choice for axle and driveline repairs where pinion bearing wear can affect gear mesh and operating smoothness.

Common Issues This Part May Address

• Pinion bearing noise from the differential area
• Excessive play or looseness in the driveline
• Wear related to radial or axial load handling
• Rough operation caused by bearing surface damage
• Service needs during differential rebuilds

Installation Notes

Inspect the mating cup and cone surfaces before installation. Replace both bearing components at the same time when the application calls for a matched set, and verify correct preload and gear setup during differential service. Clean all contact surfaces and follow the vehicle service manual for torque and adjustment procedures.

Quality Assurance

Timken is known for tapered roller bearing engineering used in driveline and axle service. The 55175C follows that bearing design approach for applications that require load capacity, fit accuracy, and consistent operation.
