3.Size Range: For yaw bearings, the outer ring diameter is 1800 - 4000mm; for pitch bearings, the outer ring diameter is 500 - 1200mm, and the height is 50 - 150mm.
4.Material: Inner ring / outer ring: 50Mn, 42CrMo; rolling elements: GCr15 bearing steel, GCr15SiMn (optional for impact resistance); seals: nitrile rubber, fluororubber (optional for oil and high temperature resistance).
5.Application Fields: 1.5 - 10MW wind turbines (yaw systems, pitch systems).
6.Key Inspection Items: Low-temperature slewing performance, anti-fatigue strength, sand and water-proof performance of seals.

Product Description

High-Performance Bearings For Wind Turbines: Engineered for Extreme Durability & Customization

When your wind energy projects demand unmatched reliability, LUOYANG INNO BEARING CO., LTD delivers Bearings For Wind Turbines that excel in harsh environments. With 30+ years of expertise, we specialize in ISO 281 and IEC 61400-certified solutions for yaw systems, pitch controls, and gearboxes—ensuring 20+ year lifespans even under -40°C temperatures or 15,000kN radial loads.

Why Our Wind Turbine Bearings Outperform

  • Yaw & Pitch Systems: Precision bearings with double-row rollers and sand-resistant seals.
  • Extreme Conditions: Operate flawlessly from -40°C to 150°C with 50Mn/42CrMo steel construction.
  • Custom Sizes: From compact pitch bearings (φ500mm) to massive yaw rings (φ4000mm+).

5 Key Advantages for Wind Farm Operators

  • Fatigue-Resistant Design: Advanced heat treatment and GCr15SiMn rollers endure 200M+ load cycles.
  • Rapid Customization: Get non-standard large diameter bearings up to φ5000mm in 15-20 days via modular production.
  • Proven Durability: 12-stage quality checks, including salt-spray corrosion tests and -50°C torque validation.
  • Global Stock Network: 1,000+ standard bearings available for 48-hour delivery across Europe, Americas, and Asia.
  • Smart Maintenance: IoT-enabled vibration sensors predict failures 6-8 months in advance, reducing downtime by 40%.
