Hebei Hankai high pressure oil rail seal kit

The designation 20x35x7 refers to the dimensions of the oil seal. The numbers represent the inner diameter (20 mm), outer diameter (35 mm), and the thickness (7 mm) of the seal. The design of an oil seal is critical, as it must fit precisely to ensure a proper seal and prevent the ingress of dirt, dust, or moisture. The choice of material used for these seals often includes rubber compounds that enhance flexibility and resilience. Common materials include nitrile rubber (NBR), fluorocarbon rubber (FKM), and silicone, each chosen based on the specific application and operating conditions.

1. Regular Inspections Periodic checks for wear and tear on the seals can help identify any potential issues before they escalate. Look for signs of leakage, which may indicate that the seals need to be replaced.

4. Lip Seals Lip seals are suitable for both dynamic and static sealing applications. They feature a lip that runs along the surface of the cylinder, creating a barrier against fluid leakage.

3. Rod Seals Found in the rod of hydraulic cylinders, these seals prevent fluid from escaping as the rod moves in and out of the cylinder. They are crucial for maintaining pressure and ensuring proper functionality of the system.

The applications for oil seals span numerous industries, from automotive to industrial machinery. In the automotive sector, for example, oil seals are essential in engines and transmission systems, where they function to prevent oil loss and contamination. In industrial machinery, they protect bearings and other critical components, ensuring smooth operation and protecting against damage from foreign particles.
