Wind turbine blade and yaw grease

SKF Wind Turbine Blade and Yaw Bearing Grease LGBB 2
SKF LGBB 2 is a lithium complex/synthetic PAO oil based grease specially designed for extreme conditions involving very low speeds, high loads, low temperatures and oscillating conditions. This grease provides proper lubrication whether the turbine is operating or in stand-still mode, installed onshore, offshore, or in cold climate areas.
  • Excellent false brinelling protection
  • Excellent performance under high loads
  • Excellent performance at low temperature starting torque
  • Good pumpability down to low temperatures
  • Excellent water resistance
  • Excellent corrosion protection
  • High thermal and mechanical stability

Typical applications:

  • Wind turbine blade and yaw bearing applications
