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

Typical applications:

Wind turbine blade and yaw bearing applications
