Standard cylinders

HHN 805

25 MPa / 250 bar
CETOP-Europa Standard

  • Piston diameter 40 to 250 mm
  • Hunger DFE seals and bearing elements
  • Sophisticated in design and construction. Multiple time-tested in operation

12 bore sizes from 40 to 250 mm and 12 different rod diameters 22 to 140 mm.Dimensions in accordance with DIN 24334 + R58H. Ports threaded BSP or metric. Cylinder bores and piston rods are finished honed to Ra < 1 µm. Cushioning provided at each end: Fixed for bores 40 and 50, adjustable for bores 63 to 250. Check/air bleed vlaves provided at each end. Double rod cylinders are available for mounting styles LB and BB. To specify add D. ex DCB.

Maximum piston speed is limited by the port size. For piston speeds in exess 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 exact details of operating conditions.
