FAW Truck Parts-F500A-1802191 The oil seal of the primary shaft of the gearbox 527210

Description

This gearbox primary shaft oil seal (also called transmission input shaft oil seal, dimension 52×72×10) is the key sealing part mounted on the front input shaft end of the FAW heavy-duty truck transmission. It locks the lubricant oil inside the gearbox to prevent oil leakage, and stops dust, mud and water from entering the gearbox interior to protect gears, bearings and synchronizer assemblies. Made of high-temperature fluororubber material with integrated metal skeleton and spring-loaded sealing lip, it maintains stable sealing performance under high speed, strong vibration and temperature fluctuation during long-haul heavy transport. The precision ground lip reduces friction heat and shaft wear. Each oil seal undergoes strict sealing inspection and aging test before shipment. It solves gearbox front end oil seepage and premature internal component wear, serving as a reliable replacement spare part for heavy truck gearbox overhaul.
