Key Features:

  • Bore sizes available 4",4.5",5",6",7"and 8" with two rod sizes available with each bore size.
  • Customer specified stroke lengths available from 10 mm to 1300 mm. Longer strokes are available, however, subject to individual design.
  • Cylinders designed to operate at 210 Bar nominal and 250 Bar peak. Safety factor of 3:1 on yield at 210 Bar nominal pressure.
  • Designed to provide a compactande conomical design.
  • The cylinder barrel is manufactured from high strength grade SAE 1026 DOM tube. The bore
  • is precision honed and polished to a 0.4 micron finish.
  • The cylinder end cap and rear mounting clevis are welded to the Australian Standard AS4041
  • "Pressure Pipe Welding Code". This ensures full adherence to qualified procedures and post
  • weld ultrasonic examination.
  • The piston rods aremachined from high strength carbon steel and hard chrome plates and ground to a 0.2 micron finish.
  • A threaded gland facilitates assembly and disassembly and is torqued to preset limits. It houses a medium duty rod wiper to protect against contaminant ingress. It also houses a single acting rod seal and provides an extended bearing surface for longer life.
  • The piston is tightened to a preset torque and scotch keyed for additional security. It housesa double acting piston seal with integral non metallic wear rings to prevent metal to metal contact.
  • A range of rod end clevises is offered which includes spherical bearing options as well as male
  • and female plain clevises.
  • A wide range of Load Holding valve options are available including externally mounted block orthe option of having cartridge valves built into the endcap to reduce the possibility of damage. No
  • increase to cylinder closed length (ie. 'x + stroke' dimension) with endcap built-in valve option.
