Wind Energy Oil Seal
Details
Wind Energy Oil Seal is a dedicated rotary sealing component tailor-made for full wind turbine transmission and power generation assemblies. Designed to withstand year-round outdoor variable climate, wind-induced shaft runout and long-duration steady rotation, it locks gear oil and bearing grease tightly inside transmission chambers, and blocks rain, sand, ozone and salt mist infiltration. Stable sealing cuts oil consumption, avoids unplanned wind turbine shutdown, and extends the overhaul cycle of new energy wind power units.

Description

DEDE Seal Co., Ltd. is one of the most reliable manufacturers and suppliers of wind energy oil seal in China. If you're going to buy bulk wind energy oil seal made in China, welcome to get pricelist from our factory. All customized seals are with high quality and competitive price.

 

Wind energy transmission systems run non-stop day and night, facing complex combined working conditions that ordinary industrial oil seals cannot cope with: drastic seasonal temperature difference, long-term wind load causing shaft radial runout, outdoor UV & ozone aging, plus special high-viscosity wind turbine gear lubricants. Our Wind Energy Oil Seal adopts wind-oriented optimized lip curve and flexible follow-up elastomer structure, matched with reinforced anti-distortion metal skeleton. The spring pre-tightened main sealing lip automatically adapts to minor shaft swing without losing compression force, stopping internal lubricant leakage under low & medium cavity pressure. The external weather-resistant auxiliary lip acts as a first barrier against outdoor pollutants, keeping lubricant media clean and avoiding abrasive wear on bearings and gear pairs. Multiple professional rubber formulas are available for onshore wind farms, offshore wind platforms and high-speed generator shafts respectively. Matching shaft size, temperature, rotating speed, lubricant and service environment correctly can fully exert the seal's long-life performance.

 

Selection Recommendations

 

 

Five core factors need full confirmation before model selection:

  1. Actual matching shaft outer diameter and installation housing bore size
  2. Long-term continuous operating temperature range of the equipment position
  3. Rated steady-state rotating speed of the rotary shaft
  4. Lubricant category (synthetic wind turbine gear oil / extreme pressure bearing grease)
  5. Service environment type: inland dusty wind farm / coastal salt fog offshore wind farm Reasonable material matching and standardized flat installation ensure uniform lip compression, maximize sealing efficiency and prolong the overall service life of wind power equipment.

 

Typical Applications

 

 

Wind turbine core gearbox low-speed input shafts and high-speed output shafts

Wind power generator rotary bearing sealing positions

Wind turbine hydraulic pitch & yaw system rotary components

All auxiliary rotating equipment inside nacelle cabin

Complete sets of sealing spare parts for distributed small wind energy generators

 

FAQ

 

 

Q1: What is the difference between Wind Energy Oil Seal and wind turbine main shaft seal?

A: Wind turbine main shaft seals are heavy-duty super-large-diameter professional seals for main bearings. Wind Energy Oil Seal is a general-purpose lightweight wind seal widely used for auxiliary shafts, gearbox ends and small hydraulic rotary components with stronger universality.

Q2: What problems can this wind energy oil seal solve?

A: It mainly solves static standby leakage, low-temperature start-stop oil seepage, cabin humidity micro-pressure leakage and intermittent rotation oil throwing of wind turbines.

Q3: Can it adapt to extreme cold wind farm environments?

A: Yes. The cold-resistant modified rubber maintains flexibility at low temperature and ensures stable sealing in winter and high-altitude environments.
