The hydraulic seal lip seals

U-shaped ring: U-ring sealing (container seal)performance is good, but is easy to roll alone, U-shaped seal friction resistance and with the increase of pressure. Therefore, the U-shaped seal lower working pressure is only suitable for low speed or movement of the hydraulic cylinders used.
V-ring: V-ring must be compatible with the supporting ring and pressure ring, V-ring cable sealing performance is better, according to the size of the working pressure seals used to determine the number of adjustments can be compensated by means of the pressure ring seals wear, V-shaped ring disadvantage is the complex structure, the friction resistance. Therefore, the V-shaped ring appropriate only relatively low velocity higher working pressure of the hydraulic cylinder used.
YX-ring: YX-ring with a cross-sectional width height ratio greater than 2, and based on the use of stability requirements, YX-ring work lip lip is shorter than the non-working, whereby the shaped seal into hole YX YX-shaped ring and shaft seal, YX-rings can be used without rolling, so YX-ring suitable for high-pressure, high-speed selection of the hydraulic cylinder.
Hydraulic Seals-O-Ring
O-ring cross-section of the O-simple shape, made of rubber, wear resistance as polyurethane, so that the hydraulic system is mainly used for static sealing.
