759/752 Wheel Bearing For AUSTIN
The DUHUI Bearing 759/752 wheel bearing is an inch-series single-row tapered roller bearing assembly consisting of a 759 cone (inner ring) and a 752 cup (outer ring). With a 88.9 mm bore, 161.925 mm outer diameter, and 47.625 mm total width, this bearing supports combined radial and axial loads in automotive axle housings, wheel hubs, and industrial gearboxes. It matches Austin OE specification 759/752 and is cross-referenced with NTN 4T-759/752, Timken SET-508, and SKF equivalents.

Product Features
- Single-row tapered roller design supports combined radial and axial loads in one direction – suitable for automotive axle and heavy machinery applications.
- Inch-series configuration with 88.9 mm bore and 161.925 mm outer diameter matches NTN 759/752 and Timken SET-508 equivalents for direct replacement.
- Separable cup and cone construction (759 cone / 752 cup) simplifies installation and maintenance – inner ring with roller assembly can be mounted independently.
- Case carburized steel construction provides a hardened outer case with a softer core – enhances impact resistance and fatigue life under heavy-duty operating conditions.
- Class 2 precision rating ensures consistent performance and dimensional accuracy for demanding applications.
Installation Notes
- Confirm bore diameter (88.90 mm) and outer diameter (161.93 mm) match your existing bearing and housing before installation.
- This bearing is a combination of cone (759) and cup (752) – 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 vehicle or equipment manufacturer specifications – tapered rollers require proper adjustment for axle and wheel hub operation.
- Lubricate with high-quality gear oil or grease – refer to the service manual for viscosity grade and lubrication method.
