This hub is a precision-engineered component that serves as the central mounting point for the wheel and brake drum on SINOTRUK HOWO heavy-duty trucks. It is manufactured using a state-of-the-art ductile iron casting process, which provides superior tensile strength, impact resistance, and fatigue life compared to conventional gray iron. The hub features accurately machined bearing bores that ensure proper seating of tapered roller bearings, minimizing friction and heat generation during operation.
Every unit undergoes multiple quality control checks, including dimensional inspection, hardness testing, and dynamic balancing. This ensures that the hub meets the tightest OEM tolerances, resulting in smooth wheel rotation, reduced vibration, and even tire wear. The flange is designed with a precise bolt hole pattern that matches the original axle specifications, guaranteeing a perfect fit without the need for drilling or reaming.
The hub also features an optimized ribbed design that enhances structural rigidity while minimizing weight. This design promotes efficient heat dissipation from the brake area, reducing the risk of brake fade and prolonging the life of brake components. Whether you are performing a routine axle overhaul or replacing a damaged hub, this genuine part offers the reliability and performance that SINOTRUK HOWO trucks are known for.

All values are based on OEM engineering specifications for the 199112340010 hub. Minor variations may occur due to casting tolerances.
The hub is cast from ductile iron, offering exceptional toughness and resistance to shock loading, reducing the risk of fracture in harsh operating conditions.
The bearing bores are CNC-ground to exacting tolerances, ensuring optimal bearing fit and alignment, which minimizes vibration and extends bearing life.
An advanced E-coating and zinc-rich primer protect the hub from rust and corrosion, even in salt-spray and high-humidity environments.
Each unit is dynamically balanced to minimize rotational imbalance, enhancing driving comfort and reducing wear on suspension and steering components.
The ribbed design improves airflow around the brake drum, reducing brake fade and thermal stress on bearings and seals.
With its robust material and precision engineering, the hub delivers reliable performance over millions of kilometers, reducing the frequency of axle overhauls.
The rear wheel hub is a safety-critical component that directly affects wheel retention, brake performance, and axle alignment. Installing a counterfeit or low-quality hub can lead to premature bearing failure, wheel wobble, or even wheel detachment, posing serious safety risks. The genuine hub eliminates these risks through OEM-grade materials, precision manufacturing, and rigorous testing.
Advantages of choosing the authentic part:
Deruna sources this hub directly from authorized manufacturers, subjecting each unit to a thorough quality inspection before shipping. We package each hub securely to prevent damage during transit, so it arrives in perfect condition.
Proper installation and regular maintenance are key to maximizing the service life of your rear wheel hub. Follow these recommendations:
Before installing, clean the axle spindle and hub bores with solvent. Inspect for burrs, nicks, or wear that could affect bearing seating.
Apply a generous amount of EP (extreme pressure) wheel bearing grease to the bearings and the bore of the hub before assembly to ensure adequate initial lubrication.
Tighten the axle nut to the torque value specified in the SINOTRUK HOWO service manual. Over-tightening can damage bearings; under-tightening leads to play and vibration.
Re-torque the wheel nuts after the first 500 km, and inspect the hub for signs of looseness, noise, or grease leakage at every scheduled service.
Always consult the SINOTRUK HOWO workshop manual for detailed instructions, bearing preload settings, and specific torque values. Proper maintenance ensures safe and reliable operation for the life of the vehicle.
This rear wheel hub is compatible with a broad range of SINOTRUK HOWO heavy-duty trucks, including:
For models not listed, cross-reference your original hub part number with 199112340010. In most cases, this hub directly replaces the original on all SINOTRUK HOWO rear axles with 10-hole wheel mounting patterns and matching flange dimensions.
The rear wheel hub with OEM number 199112340010 represents the pinnacle of SINOTRUK HOWO engineering, combining robust materials, precision machining, and advanced corrosion protection into a single, reliable component. Its design ensures that your truck maintains optimal wheel alignment, braking efficiency, and axle stability, even under the most severe operating conditions.
