Hydraulic cylinders are core working components of excavators, and seal performance directly affects equipment efficiency and service life. Proper selection is crucial.

Selection Key Points:

  • Operating Pressure: Different tonnage excavators have different operating pressures, requiring seals of corresponding pressure ratings
  • Operating Temperature: Consider the temperature range of the equipment's working environment and select materials with appropriate temperature resistance
  • Movement Speed: High-speed cylinders require seals with low friction coefficients
  • Media Compatibility: Ensure seal materials have good compatibility with hydraulic oil
