Synthetic High Speed Bearing Grease

Product code : (GRHSB)

  • Excellent high temperature stability
  • Resists oxidation, corrosion, and water washout
  • Exceptional anti-wear protection
  • Superior load-bearing performance

Synthetic High Speed Bearing Grease

Engineered with high-viscosity-index synthetic base oil and a high-quality calcium sulfonate thickener to provide exceptional mechanical stability as well as a high dropping point. This AMSOIL Industrial Synthetic High Speed Bearing Grease also provides high load-carrying performance, excellent resistance to water washout and reduced wear and corrosion in industrial applications and pitch and yaw bearings.


  • Provides superior protection for high-performance, high-speed bearings operating under high-heat and heavy loads
  • Excellent low-temperature pumpability with high-temperature consistency


  • Exclusive formulation contains premium oxidation and corrosion inhibitors helping grease from breaking down and getting component surface damage
  • Excellent adhesion and cohesion properties resist water washout
