The difference between U-cup ring and YX-shaped seal ring
May 22, 2022
The U cup ring belongs to reciprocating motion and adopts a kind of rubber seal. The cross-section is Y-shaped, referred to as "U cup seal". It is generally used for the operating system of hydraulic or pneumatic transmission, and plays a sealing role in the piston, piston rod and cylinder body. The u cup seals can be made of high-hardness nitrile rubber, or cast with polyurethane rubber, or can be made into a combination of cloth. The product is simple in structure, good in sealing effect, and has a self-sealing effect when the pressure increases, but it is a pure rubber product under high pressure.
The roots are easy to squeeze out. General pure rubber Y-seal is suitable for oil pressure less than 16MPA, linear speed less than 0.5 m/s-1,
When the temperature is -30 to 120 °C.
YX-shaped seals for holes are suitable for all kinds of mechanical equipment with air and mineral oil as the medium. The YX-shaped sealing ring acts as a sealing ring under the conditions of temperature -40~+80℃ and working pressure P≤31.5MPa. The YX-shaped sealing ring for holes is kept sealed by its open lip clinging to the sealing surface. It can usually be used alone. It has good sealing performance, low friction resistance, good pressure resistance and good working stability. long lasting.
