Product Features
- Single-row tapered roller design supports combined radial and axial loads in one direction – suitable for automotive axle and wheel hub applications.
- Inch-series configuration with 34.925 mm bore and 73.025 mm outer diameter matches Timken SET321 and Ford OE 25877/25820 for direct replacement.
- Separable cup and cone construction (25877 cone / 25820 cup) simplifies installation and maintenance – inner ring with roller assembly can be mounted independently.
- Heat-treated GCr15 bearing steel with precision-ground raceways ensures consistent load distribution and wear resistance.
- Open-type configuration supports splash lubrication systems common in axle and wheel hub applications.
Installation Notes
- Confirm bore diameter (34.925 mm) and outer diameter (73.025 mm) match your existing bearing and housing before installation.
- This bearing is a combination of cone (25877) and cup (25820) – the cone includes the inner ring with cage and roller set, while the cup is the outer ring.
- Inspect the shaft and housing for wear or damage – replace if scoring or pitting is present.
- Single-row tapered roller bearings must be mounted in mirror-image arrangement with a second tapered roller bearing to accommodate axial loads in both directions.
- Set bearing preload according to Ford manufacturer specifications – tapered rollers require proper adjustment for axle and wheel hub operation.
- Lubricate with high-quality gear oil or grease – refer to the Ford service manual for viscosity grade and lubrication method.
