Synthetic XDP Grease

Product code : (GRXDP)

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

Synthetic XDP Grease


AMSOIL Industrial Synthetic Extreme-Duty Performance (XDP) Grease is specifically engineered for use in wind turbine main bearings and other industrial applications. Its unique combination of synthetic base oils, calcium-sulfonate thickeners and carefully chosen additives help resolve common bearing issues, including wear, corrosion and mechanical instability of grease that leads to base oil bleed and grease thickening. Synthetic XDP Grease works exceptionally well in large, slow-speed bearings with high loads and in moisture-laden outdoor and industrial environments.


  • Exceptional corrosion protection
  • Extreme-pressure protection
  • Superior extreme-temperature performance
  • Excellent thermal and oxidative stability


  • AMSOIL Industrial Synthetic XDP Grease is an excellent choice for wind turbine main bearings, pitch and yaw bearings and other industrial applications that call for an NLGI #1.5 consistency grade.
