JM511945 Wheel Bearing
The JM511945/3920 wheel bearing from DUHUI Bearing is a single row tapered roller bearing engineered for differential and pinion applications on commercial vehicles. It matches the metric-series envelope with a 65.00 mm bore and 112.71 mm outer diameter, and cross-references to Timken JM511945/3920, SKF 3920/2/Q, and NTN JM511945/JM511910. This bearing set combines the cone JM511945 and cup 3920 for direct replacement in Meritor RTS2140 and Volvo differential applications.

Product Features
- Single row tapered roller design accommodates combined radial and axial loads in differential and pinion positions on commercial vehicles.
- Metric-series dimensions of 65.00 mm bore and 112.71 mm outer diameter match the standard JM511945/3920 envelope for direct interchange.
- Dynamic load rating of 125.00 kN and static load rating of 187.00 kN support heavy-duty truck differential bearing applications.
- Cone (JM511945) and cup (3920) are separable for simplified mounting and preload adjustment.
- Case carburized steel construction provides wear resistance under repeated high-load cycles.
Installation Notes
- Verify the 65.00 mm bore diameter and 112.71 mm outer diameter match your differential or pinion application before installation.
- This bearing is used for differential side bearing applications on Meritor RTS2140 and Volvo NH/FM/FH12 axles. Confirm your axle model and position before ordering.
- Inspect the differential carrier bore and pinion shaft for wear or damage. Clean all mating surfaces before mounting the bearing.
- Differential carrier bearings require precise preload adjustment. Follow the axle manufacturer’s specification for bearing preload and backlash.
- Use a proper bearing press and adapter set. Do not strike the bearing directly during installation.
