Six Performance Advantages
Comprehensive protection system for long-term reliable wind turbine bearing operation
Wide-Temperature Lubrication
Operating range −40°C to +140°C covers cold-start at high-latitude wind farms and high-temperature summer operation — reliable lubrication year-round.
Low-Speed Heavy-Load Capacity
Outstanding EP/AW performance for wind turbine bearing low-speed heavy-load conditions, effectively protecting bearing raceways and rolling elements.
Water Resistance & Corrosion Protection
Excellent water resistance and corrosion protection for offshore and high-humidity wind farm environments, extending bearing service life.
Structural Stability
Superior colloidal and mechanical stability maintains grease structure integrity during long-term operation, reducing re-greasing frequency.
Material Compatibility
Compatible with mainstream seal materials and bearing materials — does not attack rubber seals, ensuring reliable system sealing.
Long-Term Protection
Outstanding oxidation stability retards grease aging, supporting extended re-greasing / grease change intervals and reducing O&M costs.
Application Details
Main Bearing
Wind turbine main bearings carry enormous radial and axial loads, demanding grease with outstanding load capacity and water resistance. HITECBIO WTG100 provides reliable main bearing lubrication protection.
Generator Bearing
Generator bearings operate at high speed with elevated requirements for high-temperature stability and low-noise performance. HITECBIO WTG100 is suitable for long-term generator bearing lubrication.
Yaw Bearing
Yaw bearings carry overturning moments from wind loads under low-speed heavy-load conditions, requiring grease with outstanding EP/AW performance and water resistance.
Pitch Bearing
Pitch bearings frequently adjust blade angle under oscillating conditions, requiring grease with good fretting wear resistance and wide-temperature adaptability.
Frequently Asked Questions
Technical Q&A about HITECBIO WTG100 wind turbine bearing grease
Which wind turbine bearing positions is HITECBIO WTG100 suitable for?
HITECBIO WTG100 is suitable for wind turbine main bearings, generator bearings, yaw bearings, and pitch bearings, combining wide-temperature lubrication with corrosion protection — the recommended solution for wind turbine bearing lubrication.
What is the operating temperature range of HITECBIO WTG100?
HITECBIO WTG100 operates from −40°C to +140°C, accommodating cold-start requirements at high-latitude and high-altitude wind farms as well as high-temperature summer operating conditions.
What grease should be used for wind turbine generator bearings?
Wind turbine generator bearings require grease with wide-temperature adaptability, good water resistance and corrosion protection, and low-speed heavy-load capacity. HITECBIO WTG100 meets all these requirements and is the recommended choice for generator bearing lubrication. For ultra-low temperature applications (below −40°C), HITECBIO EAG50 (−50°C to +160°C) is available.
What is the difference between HITECBIO WTG100 and WTG200?
HITECBIO WTG100 (NLGI 1/2, −40°C to +140°C) is designed for main bearings and generator bearings, focusing on wide-temperature lubrication and corrosion protection. HITECBIO WTG200 (NLGI 2, −40°C to +150°C) covers main/yaw/pitch/hub bearings with emphasis on water resistance, corrosion protection, and long-term protection for low-speed heavy-load and complex environmental conditions.
What grease is recommended for wind turbine yaw and pitch bearings?
For wind turbine yaw and pitch bearings, HITECBIO WTG100 (wide-temperature lubrication, water resistance) or HITECBIO WTG200 (outstanding water resistance and long-term protection for low-speed heavy-load conditions) are both suitable. Specific product selection should be based on wind farm environmental conditions and turbine model — contact the HITECRUN technical team for expert recommendations.
