1. Reduce mechanical power consumption, lubricate the surface of the gears and racks and reduce frictional resistance and scuff

2. Cleaning effect: Lubricating grease circulates continuously in the lubricating gear and rack system to clean the friction surface and take away the wear debris and other foreign matter.

3. Cooling effect: The continuous circulation of lubricating grease in the lubricating gear and rack system also can take away the heat generated by friction and play a cooling role.

4. Anti-corrosion effect: an oil film is formed on the surface of the part to protect the surface of the part and prevent corrosion and rust.

5. Vibration damping and buffering effect: an oil film is formed on the moving surface of gears and racks to absorb shocks and reduce vibration.
