Hebei Hankai 35x52x7 oil seal

Cylinder seal kits are integral components of hydraulic cylinders used in excavators. These kits contain a variety of seals and o-rings made from materials such as rubber or polyurethane. Their primary function is to prevent hydraulic fluid leaks, maintain consistent pressure within the hydraulic system, and protect the internal components of the hydraulic cylinder from contaminants like dust and dirt.

1. Gaskets These are commonly used in mechanical assemblies to provide a tight seal between two surfaces. The material and design of the gasket can vary based on the environment and temperature resistance required.

Selecting the correct oil seal is crucial for the optimal performance of machinery. Using a seal that doesn’t fit properly can lead to leaks and potential failure of the equipment. Additionally, factors such as temperature range, chemical compatibility, and pressure should be considered when selecting the material for the oil seal. Consulting with a seals expert can help in determining the best options for specific applications.

The metal case reinforces the structure of the seal, allowing it to withstand external forces and maintain its shape under operational stress. Additionally, many seals feature a spring located behind the sealing lip, which exerts constant pressure on the lip against the shaft. This pressure helps maintain the integrity of the seal, especially in dynamic applications where the shaft is rotating.
