Wind turbine blade and yaw grease
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
