Oil Seal series iron shell oil seal, plastic molding (rubber product molding)

Outer iron shell oil seal, double lip, used for sealing the rotating shaft in dustproof and corrosion-resistant environments
1. Lip end: It is a wedge-shaped shape that seals the fluid by pressing the surface at the end.
2. Sealing lip: The sealing lip is a flexible elastic body designed to maintain a stable sealing effect under the influence of mechanical vibration and pressure changes of the sealing fluid, and to maintain a stable contact state between the lip and the shaft surface. In addition, the spring can increase the compression force of the sealing lip towards the shaft, playing a role in maintaining this compression force.
3. Dust lip: The dust lip is a secondary lip that does not come into contact with the spring. It plays a role in preventing dust intrusion.
4. Matching part: The matching part is used to prevent fluid leakage and invasion from the contact surface between the outer surface of the oil seal and the inner surface of the cavity while the oil seal is fixed in the cavity hole. In addition, the metal skeleton serves as a protection when the oil seal is fixed in the cavity.
