The foundation of reliable heavy-duty transportation lies in robust wheel-end components. The Sitrak Truck Rear Wheel Hub Assembly is engineered to be that cornerstone, providing the critical connection between your truck’s axle and its wheels. As an essential and genuine Sinotruk Sitrak parts, this assembly guarantees unparalleled durability, load-bearing capacity, and a perfect fit for your specific Sinotruk model. It is designed to endure the constant stress of heavy payloads, rough terrain, and high mileage, ensuring your fleet maintains optimal performance and safety standards with every journey.
The Sitrak Truck Rear Wheel Hub Assembly is a complete, pre-assembled unit that serves as the central mounting point for the rear wheels on heavy-duty Sinotruk vehicles. It is a crucial chassis component that houses the wheel bearings, provides the studs for wheel attachment, and interfaces with the brake drum or disc. This assembly is responsible for transferring the vehicle’s weight and dynamic loads from the axle to the wheels while allowing smooth rotation.
Designed specifically for the rigors of commercial trucking, it is built to handle extreme radial and axial forces. The assembly includes the main hub body, wheel studs, and critical sealing components like the oil deflector and a large-diameter sealing ring (232x249x10 mm). This robust design ensures the integrity of the wheel bearing lubrication system and protects against contaminants like dirt, water, and road debris.
Manufactured from high-strength forged or cast alloy steel, the hub undergoes precision machining and heat treatment. This process enhances its structural integrity, fatigue resistance, and ability to withstand the constant torque from wheel nuts and the stresses of heavy braking. The inclusion of ten high-tensile wheel studs ensures secure and even clamping force for the dual wheels typical on truck rear axles.
Supplied as a ready-to-install module, the Sitrak Truck Rear Wheel Hub Assembly significantly streamlines maintenance and repair workflows. It eliminates the complexities and potential errors associated with sourcing and installing individual bearings, seals, and studs separately, leading to faster service turnarounds and restored vehicle availability.
