The Role of Each Part

A. Lip end (sliding surface): The lip end is in the shape of a wedge and presses the shaft surface at the end to seal the fluid.

B. Sealing lip: It is a flexible elastomer, designed to ensure that it can maintain a stable sealing effect under the influence of mechanical vibration and pressure fluctuations of the sealing fluid, and maintain a stable contact state with the shaft surface at the end of the lip effect.
C. Dust-proof lip: The role of preventing dust intrusion. The dust-proof lip is an auxiliary lip that is not connected to the spring
 

Different materials and different model number have different appliEion scenarios and performances.

D. Fitting part: While fixing the oil seal to the cavity hole, the fitting part plays the role of preventing fluid leakage and intrusion from the contact surface between the outer peripheral surface of the oil seal and the inner surface of the cavity. In addition, the metal skeleton plays the role of fixing the oil seal on the cavity and maintaining the matching force.

- The nature of appliEion

Features:

1. Good abrasion resistance, long lifetime.
2. Without metallic contact of the sliding surfaces.
3. Control the machine's vibration.
4. Absorb the size's load.
5. Enlarge the clearance of seal's extrusion.
6. Simple groove design, and high load capacity.
7. Low repair cost.
