FAW Truck Parts-33021 Rear hub bearing external FAW J7

Description

This rear hub outer bearing is a tapered roller bearing fitted inside the truck rear wheel hub. It bears combined radial and axial loads, supporting axle weight and enabling smooth wheel rotation during heavy-duty transportation. Made of high-grade bearing steel with precision heat treatment, it maintains stable hardness, excellent wear resistance and fatigue resistance under continuous heavy load and rough road conditions. Strict clearance control guarantees consistent running performance. Every bearing undergoes dimensional inspection and rotation testing before shipment. It solves typical faults including hub abnormal noise and bearing overheating, and serves as a core replacement part for truck chassis overhaul.
