Mwe/Strange Pinion Bearing - Rear Bearing

The RATECH Mwe/Strange Pinion Bearing – Rear Bearing (HM804846) is a precision-engineered roller bearing assembly designed for heavy-duty differential applications in performance and modified vehicles. This rear pinion bearing supports the rotating load transmitted through the driveshaft to the ring and pinion gears, making it critical for maintaining driveline integrity under acceleration, cornering, and sustained torque delivery.

As a tapered roller bearing, this RATECH component is built to handle radial and thrust loads simultaneously—precisely what pinion bearings experience during gear mesh cycles. The HM804846 designation indicates a specific bore and outer diameter profile engineered to OEM or performance specifications, ensuring proper preload when installed with its matching cone and spacer setup. RATECH bearings are manufactured to tight tolerances and use premium materials to withstand the shock loads inherent in street and strip driving.

This rear pinion bearing is essential for rear-end rebuilds, axle swaps, and performance upgrades on vehicles running aftermarket gears or increased power output. Proper installation is crucial for optimal performance, and this bearing is compatible with various aftermarket applications. Ensure you follow installation guidelines to maximize the lifespan and effectiveness of your differential setup.
