Features:
U-cup seals rely only on the deformation of the lip in low-pressure situations. The contact area is small and the friction is relatively low.
As the pressure rises, the elastic deformation of the lip increases, the tensile, compressive and bending stresses increase, the radial pressure of the U-shaped ring automatically becomes larger, and the length of contact with the sealing surface increases until the entire axial length of the U-shaped ring is in contact with the sealing surface, thus ensuring a good seal under high pressure.
U-cup is the most commonly used oil seal in hydraulic cylinders, is a typical lip seal, whether used for piston or piston rod can get a good seal.
1) Reliable sealing performance.
2）Low frictional resistance and smooth movement.
3）Good pressure resistance, a wide range of applied pressure.
4) simple structure and low price.
5）Easy installation
Note： To avoid damage to the seal lip, take measures to avoid sharp edges when installing.
