Mobil SHC™ Grease 461 WT

Mobil SHC™ Grease 461 WT

High Performance Synthetic Grease for Wind Turbines

Mobil SHC™ Grease 461 WT

Our latest wind turbine greases are designed specifically for the extreme conditions of wind turbine operations offering a very low starting and running torque, excellent low temperature pumpability properties and enhanced wear protection.

Mobil SHC™ Grease 461 WT is engineered to push the performance of wind turbines even further, in 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
  • Circle Icon

    Excellent wear protection under fretting corrosion conditions helps reduce maintenance and unplanned equipment shutdowns.

  • Thermometer Icon

    Superior performance in low temperatures - as low as -50 degrees

  • Cog Icon

    Longer grease intervals and improved bearing life compared to Mobil SHC Grease 460 WT

Features and Benefits

•  Superb thermal stability and oxidation resistance compared to conventional greases helps provide extended service life with longer relubrication intervals for wind turbines

•  Outstanding low temperature performance compared to conventional greases provides excellent protection at low temperatures providing low torque and easy start-up at low temperatures

•  Excellent rust and corrosion protection provides enhance performance in wet conditions for reduced downtime and maintenance costs compared to/versus conventional greases

•  Outstanding structural stability in the presence of water helps retain grease consistency in hostile aqueous environments

•  Excellent low temperature pumpability provides reliable lubrication of bearings using centralized grease systems or grease dispensers.

•  Low traction base oil coefficient offers potential improved mechanical life and reduced energy costs versus conventional greases.

•  Increased oil viscosity for extra protection with excellent low temperature properties

•  No dye for improved housekeeping

•  Excellent performance in the Wind Industry Riffel test



Mobil SHC Grease 461 WT is an NLGI 1.5 Grade extreme pressure grease with ISO VG 460 synthetic base fluid recommended for tough wind turbine applications
