Lubricant oil is a product consisting of base oil, generally derived from petroleum, and some additives (compounds added to the base oils, normally in small quantities, to give a finished lubricating oil with the desired quality for the type of application wanted).

Lubricants reduce friction between two surfaces in contact and moving relative to each other, as well as carrying out other vital functions for the operation of machinery

The Role of a Lubricant

The primary functions of a lubricant are to:

  • Reduce friction
  • Prevent wear
  • Protect the equipment from corrosion
  • Control temperature (dissipate heat)
  • Control contamination (carry contaminants to a filter or sump)
  • Transmit power (hydraulics)
  • Provide a fluid seal
