What is Lubricant


  • Definition

    Lubrication refers to the reduction of mechanical losses while making movement more harmonious by reducing frictional resistance through the supply of an appropriate substance (liquid or solid) between the frictional surfaces of 2 moving objects. Lubrication prevents damages to surfaces by separating the moving objects relative to each other by means of a membrane; the substance used in such situations is referred to as a lubricant.

  • Application

    Every moving machinery requires lubrication.

    • Internal combustion engines

      In automobile, motorcycle, ship, train, etc. Transmissions and axles

    • Industrial machinery

      Hydraulic system, compressors, gears and turbines, etc.

  • Composition

    Lubricant is composed of base oil and additives, and the composition ratio varies depending on the type and viscosity of Lubricant.

    Viscosity Modifier Additives 20%

    It supplements any deficiencies in the properties of base oil

    Base oil 80%

    It takes up most of the lubricants. It determines the basic physical properties of lubricants

    Configuring Viscosity Modifier Additives
    • Viscosity Modifier
    • Dispersant
    • Detergent
    • Anti-oxidant
    • Anti-Wear Agent
    • Other additives (pour point depressant, anti-foamer, friction modifier)
  • Function

    • Reduce friction / wear

      Lubricants reduce wear and friction on surfaces of metals by forming an oil film.

    • Cooling

      Lubricants discharge the heat generated by friction and the lubrication system absorbs the heat.

    • Cleaning

      Lubricants prevent the entry of impurities such as metal fragments, dust of carbonized substances from incomplete combustion.

    • Anti-rust(chemical protection)

      Lubricants protect the lubrication surface from rusting due to corrosive gas, moisture, or oxygen in the air.

    • Enclosure

      Lubricants seal the contacting section of the machine by preventing the leakage of gas injected into the cylinder or the entry of water or dust into the cylinder.

    • Dispersion of forces

      Lubricants uniformly disperse forces locally applied to frictional surfaces.
