Excavator Piston Oil Seals OUY Adjust Seals Hydraulic Piston Seal

Feather:

• High wear resistance
• High impact resistance
• Anti-extrusion
• Small compression deformation
• Adapt to the toughest working condition
• Sufficient lubrication due to the pressure medium of between the sealing lip
• Prevent outer air entering
• Easy installation

Application Of OUY:

Piston seals or piston rings are used in hydraulic cylinders for fluid sealing and are designed to ensure that pressurized fluid does not leak across the cylinder head as the system pressure pushes the piston down the cylinder bore. Leakage through the piston seal can reduce equipment performance, and also in extreme cases can cause environmental issues. OUY is mainly used for piston seals of tensioning cylinders of construction machinery such as forklifts, excavators, etc. Has the characteristics of wear resistance, high pressure resistance, aging resistance, corrosion resistance.

Basic Requirements for Sealing Materials:

The performance of the sealing material is an important factor to ensure effective sealing. The selection of the sealing material is mainly based on the working environment of the sealing element, such as the temperature, the working pressure, the working medium used, and the movement mode. The basic requirements for sealing materials are as follows:

1. Have certain mechanical properties, such as tensile strength, elongation, etc.;

2. Appropriate elasticity and hardness, small compression set;

3. High temperature and low temperature resistance, no decomposition or softening at high temperature, and no hardening at low temperature;

4. It is compatible with the working medium, without swelling, decomposition, hardening, etc.;

5. Good oxygen resistance and aging resistance, durable;

6. Abrasion resistance, no corrosion to metal;

7. Easy to shape and process, low price.
