Grease (lubricant) - Wikiped...

Grease is a semisolid lubricant. Grease generally consists of a soap emulsified with mineral or vegetable oil.[1] The characteristic feature of greases is that they possess a high initial viscosity, which upon the application of shear, drops to give the effect of an oil-lubricated bearing of approximately the same viscosity as the base oil ...

1. LUBRICANTS WHAT THE EXPERTS SAY: • A film of lubricant (oil film) between the balls or rollers and the bearing raceway prevents wear and seizure. • Lubrication protects components from corrosion. • Lubrication also protects the components from liquids and external pollution, and evacuates wear debris. • Lubrication reduces friction, reducing the power consumed by the machine, and ...

Disadvantages of solid lubricants: Higher coefficient of friction and wear as compared to hydrodynamic regime. Low stability of the lubrication film. Less convenient system of the lubricant delivery to the friction surfaces. In contrast to solid lubricants fluid lubricants are continuously supplied, filtered and cooled.

Lubricant - Wikiped...

A lubricant is a substance, usually organic, introduced 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. The property of reducing friction is known as lubricity.
