Its tapered roller design allows it to withstand heavy radial and axial forces generated during vehicle operation. Precision-ground rollers and raceways ensure smooth rotation, reduced friction, and stable wheel alignment. Built from hardened alloy steel, the bearing provides excellent durability, heat resistance, and long service life even under demanding conditions.
By supporting the inner side of the rear axle hub, this bearing enhances drivetrain performance, reduces wear on hub components, and ensures safer, smoother vehicle operation. It plays a crucial role in maintaining load balance and wheel stability during long-haul and heavy-duty applications.
