Types Of Greases

Lithium, Calcium, Soda, Aluminum, Complex and Mixed soap base Greases, Soap free Grease, PTFE, Silicone and Molybdenum modified Greases, Specialty and Synthetic Greases.

Basic Definition

The original Definition of ASTM of Grease was “½ solid or semi solid combination of petroleum products and a soap or mixtures of soaps with or without fillers, suitable for certain types of lubrication.

Subsequent technological advances have led to the use of synthetic lubricating fluids on the one hand and non-soap thickeners on the other hand.

Current – Modified Definition of Grease is “A solid or semi solid product of dispersion of thickening agent in liquid lubricant. Other ingredients imparting special properties may be included.

Most greases are in fact is a combination of petroleum oils and metallic soaps.

Grease is a lubricant of higher initial viscosity than oil, consisting originally of a calcium, sodium or lithium soap jelly emulsified with mineral oil.

Greases are typically used in areas where a continuous supply of oil cannot be retained, such as open bearings or gears.

Grease is a fine dispersion of an oil-insoluble thickening agent – usually soap in a fluid lubricant which is generally mineral lubricating oil. The soap is made up of fatty acid, tallow or vegetable oil saponified with alkali which can be hydrated lime, caustic soda, lithium hydroxide or aluminum hydroxide. The lubricating oil component is refined base oil-naphthenic, of medium viscosity index, or cylinder oil stock. Structurally grease is a water-in-oil emulsion. Its appearance is smooth, mostly translucent, soft or hard.

Properties essential for performance of grease are structural stability, lubricating quality, (which are provided by the selected lube oil base stock), where as properties such as water resistance, high temperature quality, resistance to break down through continuous use and ability of grease to stay in place are provided by the soap.

Additives e.g. Graphite, modified clay, asphalt, oxidation and corrosion inhibitors, extreme pressure additives molybdenum disulphide etc. are used to impart specific properties as required by end application.

Factors to be considered when selecting greases are the type of grease, which in turn depends on operating temperatures, water resistance, oxidation stability etc. The second factor, no less important, are the grease’s characteristics, including viscosity and consistency.

Basic Types Of Grease


Metallic soaps + Lubricating Oils + Additives for imparting Special properties


Thickening Agent + Lubricating Fluid (Synthetic oils) + Additives for imparting Special properties

The value of plastic lubricants has been recognized since very early times when animal fats were used for Axles and the like. In general any lubricating fluid can be gelled by means of a suitable thickness to form a lubricating Grease. In practice mineral oils are almost exclusively used. For soap type Greases mineral oils of relatively low viscosity index 60 are preferred since the greater solvency of the more aromatic oils for soaps makes manufacture easier and gives greases with lower soap contents and with better properties.

Synthetic Fluids

Esters and silicone are used, only in greases for special applications, where cost is secondary to performance to meet low temperature and high temperature requirements; – 75ºC to + 320ºC.

The Soaps used are the metallic salts of long chain fatty acids derived from wide range of natural fatty materials. Soaps are mainly produced by specifying the fat or fatty acid with appropriate alkali in the presence of oil.

In some cases per-formed soaps are used, such as aluminium stearate, lithium sterate etc.

Non Soap – Thickners

may be inorganic e.g. silica or clay or organic with a very high melting point . e.g. terephthalamates, arylureas (these may be either pre-formed or formed in situ) and the dye stuffs, indenture and phthalscyanine. They need to be oleophilic and this characteristic may be imparted either in the thickner formulation (i.e. by including a long chain hydrocarbon chain or surface esterification ) or by coating the particle surfaces with organic cations. In the latter case about 75 percent of the particle surface is covered, which gives the desired effect without affecting inter –particle forces too much. Pre-treated clays (i.e. coated and dried) need aids to facilitate dispersion in oil. These dispersion aids are low molecular weight polar organic compounds such as methanol, acetone, diacetone Alcohol and propylene Carbonate.

A satisfactory Grease for a given application is expected to:

  • Provide adequate lubrication to reduce friction and to prevent harmful wear of bearing components.
  • Protect against corrosion.
  • Act as a seal to prevent entry of dirt and water.
  • Resist leakage dripping or undesirable throw off from the lubricated surfaces.
  • Resit objectionable change in structure or consistency with mechanical working (in the bearing) during prolonged services.
  • Not stiffen excessively to cause undue resistance to motion in cold weather.
  • Have suitable physical characteristics for the method of application.
  • Be compatible with elastomer seals and other materials of construction in the lubricated portion of the mechanism.
  • Tolerate some deqree of contamination, such as moisture, without loss of significant characteristics.
  • <

Soap Greases consist of dispersions of soap fibres in oil in concentrations mostly in the range 5 to 22%. By weight sometimes solid block greases contain 50 to 40% of soap.

The thickeners in non-soap greases are usually particulate rather than fibrous in nature and in this case the structure is maintained by 3 dimensional linkages due to very short range inter –particle forces (Vander waal’s forces). These linkages are readily broken and re-formed.


1. Pumping of raw material from storage tanks into day tanks.
2. Raw materials measurement by volume or weight using weighing scales, meters, tank gauges etc.
3. Preparing the soap by heating and premixing fat and lube oil in kettles with counter rotating scraper stirrer operated by motor and reduction gear.
4. Cooling of the prepared soap and balancing with oil to prepare grease in a cooling kettle.
5. Formation of grease structure by dispersion in a milling machine under controlled moisture and temperature parameters.
6. De-aeration using de-aerator.
7. Filtering through filter.
8. Filling using weigh scales/ filling machines.
9. Instrumentation – indicators/recorders for temperature and pressure.
10. Pumps- gear and centrifugal for lube oils, vegetables oils, liquid soap and grease at various stages of manufacturing.
11. Material handling equipment like hoist, pallet trucks, and fork lifts to handle solid fats, additives, alkali, drums etc.
12. Safety and fire protection devices.
13. Lab equipment.
14. Utilities like hot oil system, cooling system, air compressor, water etc.
