Product Details

Heavy duty shock absorber

HD Series

Product introduction

HD Series

HD heavy duty shock absorber provides a safe working environment for large machinery. Under the premise of meeting industrial safety standards, CJAC has designed a large-scale hydraulic damper with large bore diameter, long travel, and high absorption energy. It is suitable for various working conditions and realizes stable linear deceleration of large mechanical equipment.

  • Material

    Outer pipe: Galvanized treatment enhances rust resistance

    Piston rod: hard chromium plating treatment and special seals for longer lifespan

    Piston: We adopt materials with excellent wear resistance to ensure long-lasting and stable cushioning

  • Applications
    Automatic storage system, transmission system, gantry crane system, cement machinery system, paper machinery system, large production line, large robotic arm, rubber & plastic machinery, vehicle manufacturing, shipyard, petrochemical plant, steel & heavy industry, transportation, freight Cars, bulldozers & excavators, handling machines, cranes, mines, mine carts, railway blockers, railways, gates, port machinery, environmental protection facilities, etc.
  • Temperature
    -10~+80°C
  • Installation
    CJAC provides you with flanged tripods and other installation methods.
  • Special demands
    CJAC is able to customize solutions based on your requirements.
