55200 Wheel Bearing
The DUHUI Bearing 55200 is a single-row tapered roller bearing cone with a 50.80 mm inner diameter and 1.0594 inch (26.91 mm) cone width. This automotive wheel bearing is designed for combined radial and axial loads and is commonly used in rear inner differential pinion positions on Ford and International vehicles. It serves as a direct replacement for workshops, distributors, and B2B buyers requiring a reliable bearing solution.

Product Features
- Single-row tapered roller bearing design accommodates high radial and axial loads in one direction. The conical raceways allow these versatile bearings to support combined loads effectively.
- Separable cone and cup components simplify mounting, dismounting, and maintenance. The cone unit consists of an inner ring with cage and roller set, while the cup is the outer ring.
- Manufactured to OE specifications with case carburized steel – provides a hard, wear-resistant outer shell and a tough ductile core for excellent shock resistance and extended service life.
- Steel cage provides reliable roller guidance under load.
- Direct interchange with multiple major brand equivalents including Timken 55200, NSK 55200, and NACHI 55200/55437.
- Available for product customization – logo, code, pattern, or words can be applied to the bearing or packaging.
Installation Notes
- Confirm inner diameter (50.80 mm) matches your shaft before installation.
- This is a single-row tapered roller bearing cone – the matching cup (e.g., 55437, 55443, or 55444D) must be installed together with this cone. These bearings must be mounted in mirror-image arrangement together with a second tapered roller bearing.
- Inspect the shaft surface for wear or damage before installing new components.
- Apply even pressure when pressing the cone onto the shaft – never apply force directly through the rolling elements.
- Proper bearing preload is critical for tapered roller bearings – refer to the vehicle service manual for torque specifications.
- Pack the bearing with high-quality grease before installation if not pre-lubricated.
