Description

When a load has to move without rotating and without an extra guide, the guided drive DFM-20-25-P-A-GF is the compact choice. Piston Ø 20 mm, 25 mm stroke and plain-bearing guide are combined in a housing made of wrought aluminium alloy.

Benefits

  • 188 N advance force and 141 N on the return stroke at 6 bar, piston Ø 20 mm
  • Payload up to 64 N at 50 mm centre-of-gravity distance from the yoke plate
  • Plain-bearing guide for torque loads up to Mx 1.75 Nm
  • Elastic cushioning at both ends, impact energy in end positions up to 0.2 J
  • Position detection via proximity switch, M5 port
  • Corrosion resistance class CRC 1, ambient temperature -20 to 80 °C

Applications

Fields of use are assembly machines, feeding systems and test fixtures. The operating pressure of 2 to 10 bar and the M5 port suit standard compressed air networks with air treated to ISO 8573-1.
