The Differential Taper Roller Bearing is a OE MATCH drivetrain component designed to support and stabilise rotating differential components while allowing them to operate smoothly under heavy load. Tapered roller bearings are specifically engineered to handle both radial and axial forces, making them ideal for high-stress drivetrain applications such as the differential assembly.
