● Characteristics :
Good sealing performance, good wear resistance, extrusion resistance, impact resistance,
small compression deformation, wide application and easy installation.
● About Oil Seals Rings :
U-shaped seal in the case of low pressure,
only by the lip of the interference deformation to produce a seal,
because the contact area is small, the friction is relatively low, as the pressure rises,
the lip elastic deformation increases, tensile, compressive and bending stress increases,
U-ring radial pressure automatically becomes larger, and the length of contact with the sealing surface increases
until the entire length of the U-ring axial contact with the sealing surface, thus ensuring a good seal in the high-pressure state.
U-shaped seal is the most commonly used oil seal in hydraulic cylinder, is a typical lip seal, whether used for piston or piston rod can get a good seal.
