Mobil SHC Grease 461 WT
Mobil SHC Grease 461 WT is a high-performance synthetic lithium complex grease specifically developed for wind turbine applications operating under extreme temperature conditions. It is formulated using advanced synthetic base fluids with a low traction coefficient to provide excellent low-temperature pumpability and very low starting and running torque. The formulation is designed to deliver reliable lubrication and extended service life in demanding wind turbine bearing applications.
One of the key advantages of Mobil SHC Grease 461 WT is its excellent thermal stability and oxidation resistance. These properties help extend grease life and allow longer relubrication intervals, reducing maintenance requirements in wind turbine systems. The grease also provides outstanding low-temperature performance, enabling easy start-up and reliable lubrication in cold climate environments.
Mobil SHC Grease 461 WT also offers excellent protection against wear, rust and corrosion. The advanced additive system helps protect bearings operating in wet or harsh conditions, contributing to improved reliability and reduced downtime. Its strong structural stability in the presence of water helps maintain grease consistency and performance in hostile environments.
Another important benefit is its excellent pumpability and compatibility with centralized lubrication systems. Mobil SHC Grease 461 WT can be applied using grease dispensers or manual lubrication methods. The low traction synthetic base fluid may also contribute to improved mechanical efficiency and reduced energy consumption compared with conventional greases.
Mobil SHC Grease 461 WT is recommended for lubrication of yaw, pitch and generator bearings in wind turbines. It meets the requirements of many wind turbine builders and component suppliers and is suitable for heavily loaded bearings where reliable low-temperature performance is critical. The recommended continuous operating temperature range is approximately −50°C to 150°C with appropriate relubrication intervals.
Physical characteristics include NLGI 1.5 consistency with a synthetic base oil viscosity of approximately 460 mm²/s at 40°C. Mobil SHC Grease 461 WT has a dropping point of approximately 255°C and provides a four-ball weld load of approximately 250 kgf. The grease also delivers excellent water resistance, strong corrosion protection and reliable performance in demanding wind turbine bearing applications.
