The WG9112340113-WG9112340114 Wheel Hub Oil Seal is a precision-engineered component that upholds the rigorous standards of SINOTRUK’s original equipment. Manufactured using high-quality nitrile rubber (NBR) with a metal reinforcing casing, this seal provides a robust barrier against oil leakage and external contaminants. The sealing lip is designed with an optimized geometry to maintain consistent contact pressure against the hub or axle surface, ensuring reliable sealing even under shaft deflection or vibration.
With the WG9112340113-WG9112340114 reference number set, this seal is precisely dimensioned to fit SINOTRUK Howo front and rear wheel hubs, ensuring a leak-free interface. The double-lip design (primary and dust lip) offers enhanced protection against dirt, water, and road debris, while the integrated garter spring maintains lip tension over the seal’s lifetime, adapting to minor wear and thermal expansion.
Key Features
The precision‑formed primary lip and constant‑force garter spring ensure a tight seal against the running surface, preventing oil leaks that can lead to bearing failure and unsafe operating conditions.
The secondary dust lip effectively blocks dirt, water, and road spray from entering the hub, preserving the integrity of the bearing lubricant and extending bearing life.
Manufactured to the exact dimensions of the original parts, this seal set ensures a perfect fit without modifications, simplifying installation and reducing the risk of improper sealing.
Front & Rear Wheel Hubs: Ideal for both drive and non-drive axles on SINOTRUK Howo trucks, providing a reliable seal for the wheel bearing cavity.
Fleet Maintenance Programs: Essential for scheduled wheel‑end overhauls, helping to prevent unplanned downtime due to bearing contamination or lubricant loss.
Severe Duty Operations: Construction, mining, and off‑highway vehicles benefit from the seal’s resistance to abrasive dust and moisture ingress.
Every WG9112340113-WG9112340114 oil seal undergoes rigorous testing to ensure dimensional accuracy, lip geometry, and material compliance. The NBR compound is formulated to resist degradation from petroleum‑based lubricants, additives, and temperature extremes, while the metal casing provides structural stability during installation and service.
The garter spring is manufactured from corrosion‑resistant steel to maintain consistent tension over millions of shaft revolutions. With the WG9112340113-WG9112340114, fleet operators can expect extended wheel bearing life, reduced lubricant consumption, and fewer roadside breakdowns, contributing to overall operational efficiency.
Test Highlights
The WG9112340113-WG9112340114 seal set is designed as a direct replacement for the original hub seals on SINOTRUK Howo trucks. It fits both front and rear wheel hubs that use the standard bore and shaft dimensions. Before installation, always clean the hub bore and the axle or spindle surface to remove any old seal residue or burrs that could damage the new seal.
Installation is straightforward: use a suitable seal driver to press the seal evenly into the hub bore until it seats flush with the hub face. Apply a thin coat of clean oil to the sealing lip before assembly to prevent dry start‑up. For best results, pair the WG9112340113-WG9112340114 with new wheel bearings and lubricant, and follow the manufacturer’s torque specifications for the hub nut to ensure correct bearing preload.
The WG9112340113-WG9112340114 seal set is built to the same exacting standards as the original SINOTRUK part, guaranteeing a reliable sealing solution for your wheel ends.
With this oil seal, you prevent costly bearing failures, maintain proper lubricant levels, and reduce the frequency of wheel‑end maintenance intervals.
Choosing the WG9112340113-WG9112340114 means investing in long‑term reliability and reduced operating costs — a smart decision for any fleet or independent operator.
In summary, the WG9112340113-WG9112340114 Wheel Hub Oil Seal delivers the performance and durability required for SINOTRUK Howo heavy‑duty applications. Its advanced lip design, quality materials, and exact fit ensure that your wheel bearings remain properly lubricated and protected from external contamination. When it is time to replace your hub seals, this set offers the reliability and value that your truck deserves. Trust the WG9112340113-WG9112340114 to keep your wheel ends safe and efficient, mile after mile.
For genuine SINOTRUK Howo replacement parts, always verify the OEM numbers — WG9112340113-WG9112340114 — to ensure you receive the correct seal for your vehicle. With proper installation and routine inspection, this oil seal will provide years of dependable service, making it the ideal choice for every SINOTRUK Howo owner.
