- Reduce friction and wear, reduce frictional resistance, save energy , reduce wear, prolong mechanical life, and improve economic benefits;
- Cooling, friction heat should be discharged from the machine at any time;
- Sealed to prevent leakage, dust and gas channeling;
- Corrosion-resistant and rust-resistant, it is required to protect the friction surface from oil deterioration or external erosion;
- Clean and rinse, and clean and remove scale from the friction area;
- Stress dispersion buffer, load dispersion, impact mitigation and shock absorption;
- Kinetic energy transmission, hydraulic system, remote control motor, friction stepless speed change, etc.
