Description
The Festo guided drive DFM-80-25-P-A-KF combines a double-acting cylinder with a recirculating ball bearing guide and yoke. At 6 bar it delivers 3016 N on the advance stroke and 2827 N on the return stroke, with a stroke of 25 mm.
Benefits
- 3016 N advance force and 2827 N on the return stroke at 6 bar, piston Ø 80 mm
- Payload up to 220 N at 125 mm centre-of-gravity distance from the yoke plate
- Recirculating ball bearing guide for torque loads up to Mx 17.1 Nm, lateral forces Fy 2048 N and Fz 2048 N
- Copper and PTFE-free, RoHS compliant
- Elastic cushioning at both ends, impact energy in end positions up to 0.75 J
- Position detection via proximity switch, G3/8 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 220 N set the frame for sizing.
