- Manufactured to OE specifications with high-carbon chromium bearing steel for durability and fatigue resistance.
- Stamped steel cage provides reliable roller guidance under load.
- Direct interchange with OE number 31314 and multiple major brand equivalents.
- Available for product customization – logo, code, pattern, or words can be applied to the bearing or packaging.
Installation Notes
- Confirm bore diameter (70.00 mm) and outer diameter (150.00 mm) match your housing and shaft before installation.
- This is a single-row tapered roller bearing – verify your application requires this configuration and check the required preload specifications.
- Inspect the housing and shaft surfaces for wear or damage before installing new components.
- Apply even pressure when pressing the cone onto the shaft and the cup into the housing – never apply force directly through the rolling elements.
- Proper bearing preload is critical for tapered roller bearings – refer to the vehicle service manual for torque specifications.
- Pack the bearing with high-quality grease before installation if not pre-lubricated.
