Shacman Gearbox Rear Flange JS220-1707159-7

truck parts Shacman Gearbox Rear Flange JS220-1707159-7

Core Features & Advantages

• High-Strength Material Selection: Forged from high-quality alloy steel, undergoes strict heat treatment process. Boasts excellent tensile strength, impact resistance and fatigue resistance, capable of withstanding high torque and heavy load during long-term operation​

• Precision Machining: Adopts CNC precision machining technology for key surfaces and connection ports. Ensures dimensional accuracy within ±0.02mm, guarantees tight fit with gearbox output shaft and drive system components, eliminates power loss during transmission​

• Reliable Sealing Performance: Equipped with integrated sealing groove design, compatible with standard oil seals. Prevents lubricating oil leakage and external dust, water and other impurities from entering the transmission system, protecting internal components from wear​

• Direct Installation Compatibility: Fully matches Shacman JS220 gearbox mounting dimensions and connection standards. Enables direct bolt-on installation without modifying vehicle structure or adapting parts, reducing installation time and labor costs​

• Corrosion & Wear Resistance: Surface treated with electrophoretic coating or galvanizing technology. Enhances corrosion resistance in harsh environments such as rainy, snowy or coastal areas, extends service life by resisting oxidation and wear​

• Stable Torque Transmission: Optimized structural design distributes stress evenly. Ensures stable torque transfer even under extreme working conditions such as heavy load climbing and long-distance high-speed driving, avoiding component damage caused by uneven force
