Calcium Grease

The term grease is used to describe semisolid lubricants. Although the word grease is also used to describe lubrication. Grease 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 used in the grease.

Greases are applied to mechanisms that can only be lubricated infrequently and where a lubricating oil would not stay in position. They also act as sealants to prevent ingress of water and incompressible materials. Grease lubricated bearings have greater frictional characteristics due to their high viscosity.
