The skeleton oil seal for the rotating shaft is composed of a metal skeleton, a spring and a rubber sealing part. The metal skeleton plays a supporting role. The spring exerts a radial pressing force on the sealing lip. The sealing lip prevents the leakage of lubricating oil and the dust lip prevents external dust from entering. . It is suitable for the situation where one side has sealing medium and the other side has dust.

Material：
The rubber sealing part is nitrile rubber NBR; or fluorine rubber FKM;
The skeleton is low carbon steel.
performance：
Good dynamic sealing performance;
Compensation for various thermal expansions;
Reduce the risk of wear erosion;
Effectively prevent the intrusion of air-side pollutants;
Can withstand higher surface roughness;
Advanced lip design provides less radial force.
Working conditions：
Pressure: ≤0.05MPa
Speed: ≤20m/s (depending on the material of the rubber);
Temperature: -40°C ~ +160°C (depending on the material of the rubber);
Media: Mineral-based hydraulic fluids and synthetic hydraulic fluids (CLP, HLP, APGL, etc.).
