These two new products, designed specifically for the extreme conditions of wind turbine operations, offer a very low starting and running torque, excellent low temperature pumpability properties and enhanced wear protection.

Compared to Mobil SHC Grease 460 WT, Mobil SHC Grease 461 WT and Mobil SHC Grease 681 WT are engineered to push performance even further, in the many ways that really matter to operators.

• Easier start-up at low temperatures
• Low temperature characteristics with improved flow, reduced distribution pressures and reduced bearing torque
• Optimum oil separation for improved performance in centralised lubrication systems
• Improved water wash resistance
• Enhanced mechanical stability
• Longer term rust and corrosion protection
• Added protection against False Brinelling
• For Mobil SHC Grease 681 WT, improved oil film thickness

Key Benefits

• Excellent wear protection under fretting corrosion conditions helps reduce maintenance and unplanned equipment shutdowns
• Superior performance in low temperatures
• Longer grease intervals and improved bearing life compared to Mobil SHC Grease 460 WT
• Extreme protection in extreme weather conditions

Specially selected performance additives help deliver excellent protection against wear, rust and corrosion in extreme conditions.

• Arctic to desert temperatures: < -50 °C to 55 °C
• Arctic to mountains: extreme ice and fluctuating winds
• Offshore: Saltwater ingress and contamination
• Desert: Sand intrusion and resulting abrasion

Designed Specifically For Wind Turbines

For all year-round operation even in harsh winter conditions, these two greases ensure reliable bearing protection that helps deliver sustained productivity. The greases have been specifically designed to protect the components that need them most, namely the main bearing, pitch bearing and yaw bearing
