Hebei Hankai metric rod wiper seals

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 typical construction of a skeleton oil seal includes an outer casing that fits snugly into the housing, a sealing lip that makes contact with the rotating shaft, and a metallic reinforcement that provides rigidity. This combination of materials ensures that the seal is capable of handling the dynamic conditions of machinery while maintaining an effective barrier against the ingress of dirt and the egress of lubricants.

The design often includes a lip or multiple lips that create an effective barrier against leaks. Depending on the application, some oil seals are equipped with spring mechanisms that enhance their sealing capabilities, allowing for optimal performance in dynamic operating environments.
