Description
When a load has to move without rotating and without an extra guide, the guided drive DFM-20-25-P-A-KF is the compact choice. Piston Ø 20 mm, 25 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 44 N at 50 mm centre-of-gravity distance from the yoke plate
- Recirculating ball bearing guide for torque loads up to Mx 2.24 Nm, lateral forces Fy 408 N and Fz 408 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
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 25 mm stroke.
