Mobil SHC? Grease 460 WT
High Performance Synthetic Grease for Wind Turbines
Product Description
Mobil SHC? Grease 460 WT is a superior performance lubricant especially suited to exceed the demanding requirements of wind turbine applications at extremes of temperature. The unique features of synthetic base fluids are combined with those of a high quality lithium complex thickener. The wax-free nature of synthetic fluids and the low coefficient of traction provide excellent low temperature pumpability and very low starting and running torque. The lithium complex thickener contributes excellent adhesion, structural stability and resistance to water. The grease has a high level of chemical stability and is formulated with special additive combinations to provide excellent protection against wear, rust and corrosion at high and low temperatures.
Mobil SHC Grease 460 WT is specially formulated to lubricate yaw, pitch and main bearings of wind turbines and has become the first fill product of choice for many wind turbine builders and component suppliers. The reputation is based on its exceptional quality and reliability and has proven outstanding performance in more than 10,000 wind turbines worldwide.
