Product introduction: Under low pressure conditions, the U-shaped Y-shaped sealing ring only relies on the interference deformation of the lip to produce sealing. Due to the small contact area, the friction is relatively low. As the pressure increases, the elastic deformation of the lip increases. As tensile, compression and bending stresses increase, the radial pressure of the U-shaped ring automatically increases, and the contact length of the U-shaped ring continues to increase until the entire axial length of the U-shaped ring contacts the sealing surface, thus ensuring good sealing performance under high pressure. . U-shaped Y-shaped sealing ring is the most commonly used oil seal in hydraulic cylinders. It is a typical lip seal and can obtain a good seal whether it is used for pistons or piston rods.
advantage:
1. Excellent wear resistance
2. Impact resistance
3. Small compression set
4. Improved sealing performance under zero pressure
5. Suitable for harsh working conditions
6. Good sealing performance and long service life
7. Easy to install
※
Special reminder: UN/UHS/UNS is a dual-purpose seal ring for shaft and hole, the inner and outer lips are the same high, and the actual product is green or blue. The color cannot be specified, thank you for your understanding! ! ! !
