Description
WG9981032222 roller bearing is a heavy-duty rolling bearing for Sinotruk Howo heavy truck chassis and axle transmission system. It is installed in gearbox, main reducer or wheel hub assembly, serving as rotary support for shafts and gears, bearing large radial and axial combined loads during power transmission. The bearing adopts high-grade bearing steel, with precise machining of rollers, inner ring and outer ring plus advanced heat treatment. It features high hardness, excellent wear resistance and reliable contact fatigue resistance. It can withstand big torque, periodic impact and vibration caused by heavy load climbing and rough road conditions. Every roller bearing undergoes strict dimension inspection, clearance test, noise test and load fatigue test before delivery, to avoid common defects such as overheating, abnormal noise, roller pitting and seizure. It is a universal key replacement spare part for axle and gearbox overhaul. We maintain sufficient inventory and stable bulk supply for repair workshops, fleet operators, auto spare parts dealers and global cross-border export customers.
