It also serves a number of secondary functions.

It helps clean and cool down the engine parts and prevents rust and corrosion buildup.

Lubricants are either oil-based, solid, plastic, or a combination of the three. The most common lubricants are usually oil or grease, but you may also encounter dry or penetrating lubricants.

Whether used at processing machines, robots, or transport chains – lubricants are applied at all production steps within automotive production. While some components such as bearings are often lubricated for life, others have to be relubricated on a regular basis. However, manual lubrication is not always an appropriate solution. On the one hand, not all lubrication points are easy to access, on the other hand, manual lubrication often leads to inadequate lubrication or over lubrication. Both are frequent reasons for the premature failure of machine components.

A lubricant is a substance that helps to reduce friction between surfaces in mutual contact, which ultimately reduces the heat generated when the surfaces move. It may also have the function of transmitting forces, transporting foreign particles, or heating or cooling the surfaces.


What are lubricants used for?
A lubricant is a substance used to facilitate relative motion of solid bodies by minimising friction and wear between interacting surfaces.

Continuous and sufficient lubrication with an appropriate lubricant is essential for a long service life and the reliability of machine components. Automatic lubrication units supply the optimum lubrication quantity at the right time to the lubrication point. Thus, maintenance and servicing costs are effectively reduced and an accidental mixing up of .incompatible products is avoided

Particularly in rail transportation, innovative and carefully selected lubricant combinations must meet high safety requirements and be simultaneously eco-friendly and easily biodegradable. In close collaboration and joined development projects with vehicle and component manufacturers (OEM), vehicle and rail owners, operators, and maintenance companies we successfully developed lubricants that are water and oxidation-resistant and show excellent load and adhesion properties.
These special lubricants for the application in tram, metro, and train have been tailored to meet the various requirements in the sector of public transportation and railway.



Typically lubricants contain 90% base oil (most often petroleum fractions, called mineral oils) and less than 10% additives. Vegetable oils or synthetic liquids such as hydrogenated polyolefins, esters, silicones, fluorocarbons and many others are sometimes used as base oils. Additives deliver reduced friction and wear, increased viscosity, improved viscosity index, resistance to corrosion and oxidation, aging or contamination, etc.

Non-liquid lubricants include powders (dry graphite, PTFE, molybdenum disulphide, tungsten disulphide, etc.), PTFE tape used in plumbing, air cushion and others.
Dry lubricants such as graphite, molybdenum disulphide and tungsten disulphide also offer lubrication at temperatures (up to 350 °C) higher than liquid and oil-based lubricants are able to operate. Limited interest has been shown in low friction properties of compacted oxide glaze layers formed at several hundred degrees Celsius in metallic sliding systems, however, practical use is still many years away due to their physically unstable nature. 


A large number of additives are used to impart performance characteristics to the lubricants. Modern automotive lubricants contain as many as ten additives, comprising up to 20% of the lubricant, the main families of additives are:

Pour point depressants are compounds that prevent crystallization of waxes. Long chain alkylbenzenes adhere to small crystallites of wax, preventing crystal growth.
Anti-foaming agents are typically silicone compounds which increase surface tension in order to discourage foam formation.
Viscosity index improvers (VIIs) are compounds that allow lubricants to remain viscous at higher temperatures. Typical VIIs are polyacrylates and butadiene.
Antioxidants suppress the rate of oxidative degradation of the hydrocarbon molecules within the lubricant. At low temperatures, free radical inhibitors such as hindered phenols are used, e.g. butylated hydroxytoluene. At temperatures >90 °C, where the metals catalyze the oxidation process, dithiophosphates are more useful. In the latter application the additives are called metal deactivators.
Detergents ensure the cleanliness of engine components by preventing the formation of deposits on contact surfaces at high temperatures.
Corrosion inhibitors (rust inhibitors) are usually alkaline materials, such as alkylsulfonate salts, that absorb acids that would corrode metal parts.
Anti-wear additives form protective 'tribofilms' on metal parts, suppressing wear. They come in two classes depending on the strength with which they bind to the surface. Popular examples include phosphate esters and zinc dithiophosphates.
Extreme pressure (anti-scuffing) additives form protective films on sliding metal parts. These agents are often sulfur compounds, such as dithiophosphates.
Friction modifiers reduce friction and wear, particularly in the boundary lubrication regime where surfaces come into direct contact
