Description

25 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-25-25-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 105 N at 50 mm centre-of-gravity distance from the yoke plate
  • Recirculating ball bearing guide for torque loads up to Mx 5.77 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

Typical tasks include lifting and lowering components, ejecting workpieces and stop or separating functions in assembly and test stations. The 25 mm stroke and the payload of 105 N set the frame for sizing.
