AZ4071410051 shaft seal ring is an important sealing spare part for Sinotruk Howo heavy truck chassis and axle assembly. It is installed on rotating shafts such as front axle, rear axle hub or differential shaft. It prevents lubricating oil leakage inside the assembly, and blocks dust, mud and water from entering the bearing and gear chamber, protecting bearings and gear components from abrasion and corrosion. This oil seal adopts high-quality rubber composite material with metal skeleton, featuring good elasticity, high wear resistance and excellent aging resistance. It maintains stable sealing performance under high temperature, rotating friction and harsh muddy chassis environment. Each seal ring undergoes strict dimension inspection, elasticity test and leakage test before delivery. It effectively solves oil leakage problems of axle hub and shaft assembly, and extends service life of axle internal components. It is a common consumable spare part for axle overhaul. We maintain sufficient inventory and stable bulk supply for repair workshops, fleet operators, auto spare parts dealers and global cross-border export customers.
