● Characteristics :
Good sealing performance, easy installation;
impact pressure resistance; allows large extrusion gap.
● Application :
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-shaped radial pressure automatically becomes larger, and the length of contact with the sealing surface increases
until the entire length of the U-shaped ring axial contact with the sealing surface, so as to ensure that the high pressure
state has a good 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.
