1, control friction: in the friction surface to add lubricating oil, forming lubrication film, reduce friction between the metal direct contact, thereby reducing friction coefficient, reduce friction resistance to reduce power consumption.
2, reduce wear: friction between the surface has a certain intensity of the lubrication film, can support the load, to avoid or reduce the metal surface direct contact, so as to reduce the contact surface plastic deformation, melting welding, shear and other bonding and other degrees of adhesion wear.
3, cooling and cooling: lubricating oil can reduce friction coefficient, reduce friction heat generation.
4, SEALED isolation: lubricating oil in particular grease cover on the surface of friction or other metal surface, can isolate moisture, moisture and other harmful media contact with metal, thus reducing corrosion and wear, prevent rust, protect the metal surface.
5, reduce vibration: lubricating oil can impact vibration of the mechanical energy into hydraulic energy, play a mitigating impact, absorb the role of noise.
