Synthetic XDP Grease

  • Base Oil Technology: Synthetic
  • NLGI: #1.5
  • Base Oil Viscosity: 400-680
  • Thickener: Calcium Sulfonate 

AMSOIL Industrial Synthetic Extreme-Duty Performance (XDP) Grease is specifically engineered to provide superior mechanical stability in large, slow-speed, high-load wind turbine main bearings. Its unique combination of synthetic base oils, calcium-sulfonate thickeners and advanced additives fight base oil bleed and grease thickening to provide exceptional longterm wear and corrosion protection in outdoor environments and other severe-service industrial applications.

  • Superior mechanical stability for extended severe-service and extreme-pressure wear protection.
  • Exceptional protection against corrosion from condensation, water ingress and operation in wet environments.
  • Protects bearings from fluctuating wind speed and from fretting at inoperable times.
  • Maintains consistency, providing exceptional long-term bearing protection and improved efficiency.
  • Outstanding cold-flow properties for easy startups and efficient equipment operation at low temperatures.
  • Excellent thermal and oxidative stability at high temperatures.
