For heavy-duty truck operators demanding reliability and safety, the Sitrak Truck MAT16ZG Rear Axle Hub and Brake Assembly represents the pinnacle of engineering excellence. This comprehensive assembly integrates critical wheel-end and braking components into a single, cohesive system designed for maximum performance and durability. As a premier example of Sinotruk Sitrak parts, it ensures perfect compatibility with MAT16ZG rear axles, offering enhanced load capacity, superior braking performance, and extended service intervals for demanding transportation applications.
The Sitrak Truck MAT16ZG Rear Axle Hub and Brake Assembly is a fully integrated wheel-end system that combines the hub, bearings, seals, planetary reduction, and foundation brake components into one complete unit. It is specifically engineered for the MAT16ZG heavy-duty truck axle, providing a robust interface between the axle shaft and the wheel, while housing the critical braking mechanism.
This assembly features an advanced ABS (Anti-lock Braking System) compatible design, ensuring safe and controlled braking under various load conditions. The inclusion of a planetary wheel reducer (with a sun gear and internal ring gear) provides gear reduction at the wheel, increasing torque output and reducing stress on the main differential and axle shafts.
Constructed from high-grade materials, the assembly includes precision components like tapered roller bearings (30222 & 32222), multiple sealing rings, and shims for exact adjustment. The brake subsystem comprises the brake drum, shoes with linings, camshafts, automatic slack adjusters, and backing plates, all pre-configured for optimal performance.
Supplied as a comprehensive kit, the Sitrak Truck MAT16ZG Rear Axle Hub and Brake Assembly simplifies maintenance and overhaul procedures. It ensures all components work in perfect harmony, eliminating compatibility issues and reducing vehicle downtime during repairs or scheduled servicing.
