Mobil SHC™ Grease 460 WT
Mobil Grease, United States
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.
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:
| Features | Advantages ａnd Potential Benefits |
| Outstanding high temperature ａnd low temperature performance compared to conventional greases | Wide application temperature ranges, with excellent protection at high temperatures ａnd low torque, easy start-up at low temperatures |
| Superb thermal stability ａnd oxidation resistance compared to conventional greases | Extended service life with longer intervals between relubrication ａnd improved bearing life |
| Excellent protection against wear, rust ａnd corrosion | Reduced downtime ａnd maintenance costs |
| Excellent pumpability | Reliable lubrication of bearings using centralized grease systems or grease dispensers |
| Outstanding structural stability in the presence of water | Retains excellent grease performance in hostile aqueous environment |
| Low traction coefficient | Synthetic formulation delivers potential improved mechanical life ａnd reduced energy costs versus conventional greases |
Applications
Mobil SHC Grease 460 WT is an NLGI 1.5 Grade extreme pressure grease with ISO VG 460 synthetic base fluid recommended for tough wind turbine applications. It provides outstanding bearing protection under heavy loads at low-to-moderate speeds ａnd in applications where water resistance is a critical factor. Mobil SHC Grease 460 WT meets most specifications of wind turbine builder ａnd component suppliers ａnd has demonstrated outstanding performance in applications such as lubrication of yaw, pitch ａnd main bearings either manual greased or using centralized grease systems or grease dispensers. The recommended operating temperature range is -30º C to 150ºC.
