1. Reduce friction
After adding lubricant on the interactional friction surface, it will form a lubricating film which can separate the friction surfaces. The lubricating film will change the metal friction to friction between the film molecule. Then it can reduce friction and keep the equipment running well.
2. Protect against wear
Lubricant film formed on the friction surface can reduce friction and bear load, so it can prevent wear and scratch on surface and keep the spare parts match precisely。
Lubricant can take away the heat produced through friction to reduce the temperature
4. Prevent corrosion
Lubricating film on the surface can isolate air, vapor or other media to prevent corrosion and rust.
