Dongfeng VL truck spare parts Input end oil seal 2510060-ZM99A

Built to eliminate oil leakage from the transmission input end, this oil seal features an advanced dual-lip design that delivers superior sealing performance. The primary lip (primary sealing surface) uses a nitrile rubber (NBR) compound with a Shore hardness of 70±5, creating a tight contact with the input shaft’s rotating surface to block 99% of transmission oil. The secondary lip acts as a dust and water barrier, preventing road debris, mud, and moisture from entering the transmission and contaminating the oil. A built-in spiral spring applies uniform radial force (5-8N) to the primary lip, compensating for minor shaft wear and maintaining sealing integrity over time. Leakage rate is tested to ≤0.01g/h, far below the industry limit of 0.1g/h

The oil seal is crafted from premium materials to endure the harsh conditions of heavy-duty truck drivetrains. The sealing lips are made of hydrogenated nitrile rubber (HNBR) that resists degradation from transmission oil (including synthetic and mineral oils) and operates stably at temperatures ranging from -40℃ to 150℃—adapting to frigid winters and high-temperature engine compartments. The metal skeleton is constructed from SPCC cold-rolled steel with a phosphate coating, providing rigid support and resisting corrosion (passing 500-hour salt spray testing). The lip’s surface is coated with a polytetrafluoroethylene (PTFE) film, reducing friction coefficient by 30% and minimizing wear on both the seal and input shaft

Optimized to withstand the vibration and wear of heavy-duty operations, the oil seal integrates multiple anti-fatigue features. The dual-lip structure’s flexible design absorbs 60% of torsional vibration from the input shaft (up to 20g vibration loads, ISO 16750-3), preventing lip deformation and leakage. The PTFE coating on the sealing surface reduces abrasive wear, extending the seal’s service life to ≥150,000km—50% longer than standard NBR oil seals. The seal’s inner diameter features a micro-groove texture that retains a thin film of oil, lubricating the lip during rotation and further reducing wear. Even with minor shaft eccentricity (≤0.1mm), the seal maintains a consistent sealing contact, avoiding premature failure

Designed for efficient fleet maintenance, the oil seal features a user-friendly design that simplifies installation and reduces downtime. Its rigid metal skeleton ensures easy press-fit installation using a standard seal driver tool—no specialized equipment required. The outer diameter’s knurled texture enhances the press-fit retention force with the clutch housing, preventing the seal from slipping during operation. Installation takes a single technician 15 minutes to complete, 40% faster than non-OE seals with complex mounting requirements. By preventing transmission oil leakage, it reduces oil replenishment costs by 30% and avoids expensive transmission repairs caused by oil contamination. Backed by a 1-year/100,000km warranty, it is a cost-effective solution for heavy-duty truck operators
