Product Features
- Single-row tapered roller design supports combined radial and axial loads – suitable for differential pinion applications where heavy loads are encountered.
- Inch-series configuration with 44.45 mm bore and 104.775 mm outer diameter matches Ford OE 1537810 and Dana specifications for direct replacement.
- Separable cup and cone construction simplifies installation and maintenance – inner ring with roller assembly can be mounted independently.
- Heat-treated bearing steel with precision-ground raceways – rated for high dynamic and static loads suitable for heavy-duty rear axle applications.
- Cross-referenced with major brands including NSK, Timken, and ZKL – confirmed interchange available.
Installation Notes
- Confirm bore diameter (44.45 mm) and outer diameter (104.775 mm) match your existing bearing and housing before installation.
- This bearing is a combination of cone (HM807040) and cup (HM807010) – 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 or Dana service manual specifications for proper differential operation.
- Lubricate with high-quality gear oil meeting manufacturer specifications for the Dana 70 axle.
