Product Features
- Single-row tapered roller design supports combined radial and axial loads in one direction – suitable for agricultural and heavy-duty equipment drivetrain and wheel hub applications.
- Metric-series configuration with 40 mm bore and 90 mm outer diameter matches Koyo 30308DJR, SKF 31308, and Timken 31308 equivalents 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 100.0 kN dynamic load and 90.2 kN static load for demanding agricultural and industrial applications.
- Interchangeable with AGCO OE 70272712 and CASE IH 190003326072 – confirmed cross-reference available.
Installation Notes
- Confirm bore diameter (40.00 mm) and outer diameter (90.00 mm) match your existing bearing and housing before installation.
- Inspect the shaft and housing for wear or damage – replace if scoring or pitting is present.
- Set bearing preload according to vehicle or equipment manufacturer specifications – tapered rollers require proper adjustment for differential and axle operation.
- When mounted as a single bearing, a second tapered roller bearing is required in mirror-image arrangement to accommodate axial loads in both directions.
- Lubricate with high-quality gear oil or grease – refer to the AGCO or CASE IH service manual for viscosity grade and lubrication method.
