1. Control friction: Add lubricant between the friction surfaces to form a lubricating film, reduce direct metal contact between the friction surfaces, thereby reducing the friction coefficient, friction resistance, and power consumption.


2. Reduce wear: A lubricating film with a certain strength between the friction surfaces can support the load, avoid or reduce direct contact with the metal surface, thereby reducing various degrees of adhesive wear on the contact surface, such as plastic deformation, melt welding, shearing and re bonding.


3. Cooling and cooling: Lubricants can reduce the coefficient of friction and reduce the generation of frictional heat.


4. Sealing and isolation: Lubricants, especially lubricating grease, cover the friction surface or other metal surfaces, which can isolate water, moisture, and other harmful media from contact with the metal, thereby reducing corrosion and wear, preventing rust, and protecting the metal surface.


5. Reduce vibration: Lubricants can convert the mechanical energy of impact vibration into hydraulic energy, which plays a role in reducing impact and absorbing noise.
