DEDE Seal Co., Ltd. is one of the most reliable manufacturers and suppliers of wind power seal in China. If you're going to buy bulk wind power seal made in China, welcome to get pricelist from our factory. All customized seals are with high quality and competitive price.
Wind turbines run 24/7 for over 20 years under harsh open-air environments, facing unique sealing challenges that standard industrial oil seals cannot resolve: extreme cold winter startup, high-temperature gearbox operation, offshore salt corrosion, continuous shaft eccentricity from wind load, plus mixed grease & synthetic gear oil lubrication. Our full line of Wind Power Seals adopts wind-specialized lip geometry, reinforced anti-eccentric skeleton and long-life anti-aging elastomer formulas. The integrated multi-barrier double-lip layout forms dual protection: the inner spring-energized main lip retains high-viscosity gear oil / bearing grease under variable pressure; the outer heavy-duty weatherproof lip blocks sea salt mist, rainwater, sand and airborne pollutants before they contact core bearing & gearbox components. All materials comply with IEC 61400 wind power component standards, with validated long-term aging performance matching the full lifecycle of wind generators.
