Description

When a load has to move without rotating and without an extra guide, the guided drive DFM-20-80-P-A-KF is the compact choice. Piston Ø 20 mm, 80 mm stroke and recirculating ball 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 86 N at 50 mm centre-of-gravity distance from the yoke plate
  • Recirculating ball bearing guide for torque loads up to Mx 3.36 Nm, lateral forces Fy 817 N and Fz 817 N
  • Copper and PTFE-free, RoHS compliant
  • Elastic cushioning at both ends, impact energy in end positions up to 0.2 J
  • Position detection via proximity switch, M5 port

Applications

The DFM-20-80-P-A-KF works in handling modules, pick-and-place units and packaging machines, wherever a guided linear motion with 188 N is required. Any mounting position is possible.
