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.
Features and Benefits
The Mobil SHC brand of oils and greases are recognized and appreciated around the world for their innovation and outstanding performance. A key factor in the development of ExxonMobil´s products was the close contacts with key Original Equipment Manufacturers (OEMs) to ensure that our product offerings would provide exceptional performance in the continually evolving industrial equipment designs.
Our work with equipment builders has helped confirm the results from our own laboratory tests showing the exceptional performance of Mobil SHC Grease 460 WT. Compared to conventional greases the benefits of this synthetic grease include longer grease life, enhanced false brinelling protection and bearing life, wide temperature range of application, and the potential for improved mechanical efficiency.
To combat severe application conditions proprietary synthetic base oils have been chosen for Mobil SHC Grease 460 WT because of their outstanding thermal/oxidative resistance potential. A state-of-the-art lithium complex thickener technology and specific additives help to enhance the performance of Mobil SHC Grease 460 WT offering the following features and benefits:
