Product Description: UIY type sealing ring in low pressure, only by the lip of the interference deformation to produce sealing, because the contact area is small, the friction is relatively low, as the pressure rises, the lip elastic deformation increases, the tensile, compression and bending stress increases, the radial pressure of the U-ring automatically becomes larger, and the length of the contact with the sealing surface continues to increase until the entire axial length of the U-ring contact with the sealing surface, thus ensuring a good sealing under high-pressure conditions. U-ring is the most commonly used oil seal in hydraulic cylinders, it is a typical lip seal, no matter used for piston or piston rod can get good sealing.
Product features: good sealing performance, easy to install; impact pressure resistance, allowing a large extrusion gap.
Product use: used for reciprocating hydraulic cylinder piston (shaft) sealing.
Scope of application: universal lip seals for pistons and piston rods, widely used in various industries.
