Grease

Grease

The term grease is used to describe a solid lubricant with a higher initial viscosity than oil. Grease consists of oil and another fluid lubricant that is mixed with another thickener substance, called a soap, to form a solid. Greases are used in instances when a mechanism can be lubricated infrequently and lubricating oil would not stay in position. In addition, grease is a sealant, preventing ingress of water and dust. Grease-lubricated bearings have greater frictional characteristics due to their high viscosity. Under shear, the viscosity drops to give the effect of an oil-lubricated bearing of approximately the same viscosity as the base oil used in the grease. Selecting and utilizing the proper type and amount of grease is the most important factor in acheiving longer bearing life.

Lithium-based greases are the most commonly used; sodium and lithium based greases have higher melting point than calcium-based greases but are not resistant to the action of water. Lithium-based grease has a dropping point at 190 °C to 220 °C (350 °F to 400 °F). However the maximum usable temperature for lithium-based grease is 120 °C.
