THE IMPORTANCE OF BASE OIL VISCOCITY

Base oil viscosity is the most important factor for:

  • Making most use of elastohydrodynamic layer
  • Helping prevent wear in bearings
  • Selecting best grease based on application needs (speed, temperature, environment)

 

Low viscosity best for:

  • High speed, low load & low temperatures

 

High viscosity best for:

  • Low speed, high load & high temperatures
