MUS1308TM Wheel Bearing
The DUHUI Bearing MUS1308TM cylindrical roller bearing is a non-separable single-row bearing with an inner ring that has two integral ribs and an outer ring that contains two retaining rings for axial location of the rollers. This bearing is designed for high radial load capacity and accommodates bidirectional axial displacement, making it suitable for non-locating bearing positions in transmissions, differential pinions, and industrial gearboxes. The MUS1308TM meets OE specifications and is interchangeable with NTN, Bower, and Link-Belt equivalents.

Product Features
- Non-separable design with inner ring featuring two integral ribs and outer ring with two retaining rings – the rollers are held captive in the assembly, simplifying handling and installation.
- Full complement roller set (no cage) – provides maximum radial load capacity for applications where space and weight are limited.
- Non-locating bearing design – accommodates axial displacement in both directions, making it suitable for use as a free-end bearing in gearboxes and differentials where thermal shaft expansion occurs.
- ISO Class 0 (RBEC 1) precision rating – precision-ground surfaces and tight manufacturing tolerances ensure consistent performance and reliability.
- Hardened alloy steel construction – supports high radial loads with rated dynamic load of 96.0 kN and static load of 106.0 kN.
- Open configuration without oil hole – suited for splash lubrication and oil bath applications common in transmission and differential environments.
- Operating temperature range of -40 to 120 °C supports diverse automotive and industrial applications.
Installation Notes
- Confirm bore diameter (40.00 mm) and outer diameter (90.00 mm) match your housing and shaft before installation.
- This bearing is of non-separable design – the inner ring and outer ring are assembled as a unit, so handle with care to avoid roller displacement.
- Verify shaft shoulder diameters: minimum 52.10 mm for the ribbed inner ring fit; inspect both shaft and housing surfaces for wear.
- Apply lubricant appropriate for splash or oil bath lubrication – refer to your vehicle or equipment manual for viscosity recommendations.
- When using as a differential pinion bearing (as in Ford, Chevrolet, or GMC applications), follow the vehicle-specific preload and torque procedures from the service manual.
