Lubrication is simply the use of a material to improve the smoothness if movement of one surface over another; the material which is used in this way is called a lubricant. Lubricants are usually liquids or semi-liquids, but may be solids or gases or any combination of solids, liquids, and gases.
The smoothness of movement is improved by reducing friction. This is not, however, always the case, and there may be situations in which it is more important to maintain steady friction than to obtain the lowest possible friction.
In addition to reducing or controlling friction, lubricants are usually expected to reduce wear and often to prevent overheating and corrosion.
Lubrication offers a comprehensive range of speciality lubricants, comprising high-performance oils and greases as well as special pastes, waxes, bonded coatings, release agents and lubricant dispensers
