Specifications:
Model: UN, UHS, UNS
Material: Imported polyurethane material
Hardness: 90 degrees
Special reminder: UN/UHS/UNS is a dual purpose sealing ring for shaft holes, with the inner and outer lips of the same height. The actual product is green or blue, and the color cannot be specified. We hope you can understand
Product Introduction:
Under low pressure, the U-shaped Y-shaped sealing ring only relies on the interference deformation of the lip to produce a seal. Due to the small contact area, the friction force is relatively low. As the pressure increases, the elastic deformation of the lip increases, and the tensile, compressive, and bending stresses increase. The radial pressure of the U-shaped ring automatically increases, and the length of contact with the sealing surface continues to increase until the entire axial length of the U-shaped ring contacts the sealing surface, ensuring good sealing performance under high pressure. The U-shaped Y-shaped sealing ring is the most commonly used oil seal in hydraulic cylinders, and is a typical lip seal that can achieve good sealing whether used for pistons or piston rods.
