Lubricants

Lubricant can be expressed as the substance that is applied among surfaces to control the wear and tear and improve performance. Lubricants play an essential part in the safety of machinery components like gears, shaft, linkage, cam, clutches, and many others. The quantities which affect the amount of lubricant are temperature, surrounding conditions, speed of the components, and many more.
