Description

50 mm stroke, 295 N advance force at 6 bar and a recirculating ball bearing guide that keeps the load from rotating: the guided drive DFM-25-50-P-A-KF handles lifting, pushing and positioning without an additional guide.

Benefits

  • 295 N advance force and 247 N on the return stroke at 6 bar, piston Ø 25 mm
  • Payload up to 112 N at 50 mm centre-of-gravity distance from the yoke plate
  • Recirculating ball bearing guide for torque loads up to Mx 5.43 Nm, lateral forces Fy 863 N and Fz 863 N
  • Copper and PTFE-free, RoHS compliant
  • Elastic cushioning at both ends, impact energy in end positions up to 0.3 J
  • Position detection via proximity switch, G1/8 port

Applications

In feeders, assembly cells and test stations the guided drive lifts, pushes and holds loads at ambient temperatures of -5 to 60 °C. The piston rod made of high-alloy stainless steel carries the yoke over the 50 mm stroke.
