In the rail transit sector, high-speed trains, metro vehicles, and intercity railways operate under complex conditions involving high speeds, heavy loads, vibrations, temperature fluctuations, and long-term operation. The sealing performance of bearings, transmission systems, and hydraulic components directly impacts a vehicle’s safety, operational efficiency, and maintenance costs.
The V-Type Shaft Fabric-Reinforced Oil Seal Assembly is a high-performance sealing solution specifically designed for high-speed trains and metro vehicles. Featuring high-wear-resistant rubber, multi-layer reinforced fabric, and an optimized sealing lip design, this product ensures excellent sealing performance under high-speed rotation, strong vibrations, extreme temperatures, and harsh working conditions. It is widely used in train wheelset bearings, gearboxes, hydraulic systems, door mechanisms, and braking systems, effectively preventing leakage of lubricating oils, greases, and hydraulic fluids, thus enhancing the safety and reliability of rail vehicles.
Made of highly durable rubber materials such as hydrogenated nitrile butadiene rubber (HNBR), fluororubber (FKM), and polyurethane (PU) to maintain stable sealing performance under high-speed rotation without excessive wear.
Suitable for high-speed trains exceeding 350 km/h, ensuring stable sealing during long-term operation and reducing maintenance costs caused by seal failure.
Excellent fatigue resistance, minimizing stress concentration from high-speed operation and extending service life.
Multi-layer Kevlar or fiberglass fabric reinforcement enhances impact resistance, preventing seal damage due to uneven tracks or emergency braking.
Suitable for bearing housings, wheelset bearings, and traction motor seals, ensuring the seals do not deform or detach under high-speed conditions.
Dynamic adaptation design allows automatic compensation for minor deformations caused by vibrations and impacts, further extending seal longevity.
Operates efficiently in extreme temperatures ranging from -50°C to +200°C, making it suitable for cold regions (e.g., Northern Europe, Northeast Asia) and hot climates (e.g., the Middle East, Southeast Asia).
Low-temperature-resistant rubber materials (such as VMQ silicone rubber) maintain elasticity and sealing effectiveness even in freezing conditions, preventing shrinkage-related leaks.
Heat aging resistance, ideal for high-temperature environments such as traction motor seals and gearbox seals in high-speed trains.
Multi-lip sealing design enhances leakage prevention, reducing the loss of lubricants and ensuring the long-term stability of gearboxes and wheelset bearings.
Suitable for high-speed train bogie bearings and sealing systems, minimizing contamination in lubrication systems and extending maintenance intervals.
Self-compensating wear feature maintains long-term sealing effectiveness, reducing manual maintenance workloads and improving train availability.
Made from high-performance oil-resistant rubber materials, ensuring long-term contact with lubricating oils, hydraulic oils, and gear oils without swelling, aging, or failure.
Resistant to hydrolysis and moisture, making it ideal for metro vehicles and trains operating in humid coastal regions.
Dirt, dust, and contamination-resistant design, suitable for bogie assemblies and braking systems, preventing debris ingress and enhancing component durability.
A major high-speed rail operator experienced seal performance degradation in wheelset bearings, leading to lubricant leakage and affecting train stability. After switching to the V-Type Shaft Fabric-Reinforced Oil Seal Assembly, sealing effectiveness significantly improved, extending maintenance intervals by 30% and reducing maintenance costs.
A city metro operator encountered seal aging issues in traction motors due to prolonged exposure to high temperatures, impacting motor lifespan. By adopting high-temperature-resistant V-Type shaft seals, seal degradation slowed, increasing motor lifespan by 25% and improving overall operational efficiency.
An intercity train experienced lubricant leakage in its braking system, reducing braking efficiency. By implementing high-temperature and impact-resistant V-Type shaft oil seals, the leakage problem was resolved, enhancing braking system stability and safety.
