A lubricant is used to reduce friction between two objects or surfaces. Its function is to get the objects in motion as they work together for a purpose. Other than industrial applications, a lube is also used for cooking (to prevent the food from sticking), medical applications, ultrasound laboratories, and sexual enhancements.

Other functions of a lubricant (lube) are as follows:

  • To transfer heat
  • To carry away debris and contaminants - automotive engines contain detergents and additives to aid in transporting contaminants for removal.
  • To transmit power - Hydraulic fluids are the working fluids for power transmission
  • To protect against wear and tear - lubricants aid in moving parts apart. They may also contain additives to boost performance against fatigue and wear.
  • To seal for gases - through a capillary force, it occupies the clearance between moving parts to seal pistons and shafts, for instance.
  • To prevent corrosion - it prevents rust on surfaces for the best quality lubricants

Fluid type applications:

  • Industrial category
    • Hydraulic oils
    • Food grade lubricants
    • Refrigerator compressor oils
    • Gear oil
    • Air compressor oils
  • Automotive category
    • Brake fluids
    • Hydraulic fluids
    • Engine oils
      • Petrol (gasoline) oils
      • Diesel engine oils
  • Aviation category
    • Piston engine oils
    • Gas turbine oils
  • Marine category
    • Trunk piston engine oils
    • Crosshead cylinder oils
    • Stern tube lubricants
  • Motor category
    • 2-stroke engine oils
  • Sexual category
    • Personal lubricant

Beneficial key points of a Lubricant:

  • Lubricants maintain performance over a long period of time.
  • Lubricants are environment-friendly. An estimate of 40% on lubricants are recycled, burned, and disposed into the environment.

When lubricants are burned, they are used as fuel to generate electricity. Thus, lubes are generally noteworthy contributions around the globe.
