Hydraulic rod seals performance
Good compatibility Because the hydraulic seal is immersed in the hydraulic oil for a long time, it is easy to swell, dissolve or embrittlement and harden, so that it loses the sealing effect, so the hydraulic seal is required to have good compatibility with the hydraulic oil.
The frictional resistance is small to avoid or reduce the undesirable phenomenon of low pressure creeping of the hydraulic equipment. The hydraulic seal is required to have low static friction resistance and dynamic friction resistance, and the friction coefficient thereof should be very stable.
Long service life Hydraulic seals should have good elasticity, heat resistance, cold resistance, pressure resistance, wear resistance and certain physical and mechanical strength, and have a long service life.
Low-cost hydraulic seals should be easy to manufacture and install, and the corresponding seal grooves are easy to manufacture, and the processing accuracy of the seal surface is low and low.
