Import Tips
• Include bearing manufacturer specs showing compatibility with wind turbine gearbox designs (e.g
• SKF or FAG)
• Document surface hardness (HRC 58-62) and material (e.g
• 18NiCrMo5) required for wind applications
• Avoid common pitfall of classifying as general bearing housing (8483.20) by proving gearbox-specific function
