Piston Rod Seals KVK Seals U+S Mechanical Seals

Overview U+S is a combined sealing ring. The star ring ensures the pre-compression amount under low pressure or vacuum conditions, the system pressure is transmitted to the sealing lip of the U-ring through the star ring, the U-ring is loaded with the increase of the system pressure, and the sealing effect is basically related to the temperature Regardless of the change, when the U-shaped ring is worn to a certain extent, the star-shaped ring plays a compensating role to ensure its sealing effect. advantage U+S has good wear resistance and anti-extrusion performance; insensitive to shock loads and pressure peaks; ideal sealing effect under no-load and low temperature conditions; suitable for harsh working environments; easy to install. Scope of application U+S is mainly used for sealing plungers, piston rods, air drills, telescopic cylinders, forging presses and mobile machinery and other hydraulic equipment. technical parameter Pressure: ≤35 Mpa, when the pressure is higher t…
