Classification of U-ring: U-ring for shaft, U-ring for hole, U-ring for hole shaft, U-ring is a kind of sealing ring. Because of its section such as U-shaped, it is called U-shaped sealing ring, the English name U-ring. U-ring is a commonly used seal in hydraulic cylinder, it is a typical lip seal, whether used for piston or piston rod can obtain good sealing effect, U-ring in low pressure, only rely on lip interference deformation seal, due to small contact area, friction force is relatively low, as the pressure rises, lip elastic deformation increase, stretch, With the increase of compression and bending stress, the radial compression force of the U-ring automatically increases, and the length of contact with the sealing surface increases continuously, until the entire axial length of the U-ring contacts with the sealing surface, so as to ensure good sealing performance under high pressure.
The U-ring is a kind of sealing ring that acts as a seal. Because of its cross section such as U-shaped it is called U-shaped sealing ring English name U-ring.
