Steel works standard cylinders

HHN 811

35 MPa / 350 bar
CETOP-Europa Standard

  • Piston diameter 40 to 320 mm
  • Hunger DFE seals and bearing elements
  • Sophisticated in design and construction. Multiple time-tested in operation

14 bore sizes from 40 to 320 mm and 14 different rod diameters 28 to 220 mm. Dimensions in accordance with DIN 24333. Ports threaded BSP or metrc. Cylinder bores and piston rods are finished honed to Ra< 1µm. Cushioning provided at each end. Adjustable for bores 40 to 320. Check/air bleed valves provided at each end. Double rod cylinders are available for mounting styles. To specify add D. ex DLH.

Maximum piston speed is limited by the port size. For piston speeds in excess of 0.5 m/sec. please state acceleration, deceleration, load and mounting attitude. When the cylinder operates in compression always check the buckling strength of the piston rod.

We will be pleased to quote for non standard cylinders having long strokes > 3000 or other special characteristics not shown in the catalogue. Please mention in your enquiry excact details of operation conditions.
