Description
The Festo guided drive DFM-40-25-P-A-KF combines a double-acting cylinder with a recirculating ball bearing guide and yoke. At 6 bar it delivers 754 N on the advance stroke and 686 N on the return stroke, with a stroke of 25 mm.
Benefits
- 754 N advance force and 686 N on the return stroke at 6 bar, piston Ø 40 mm
- Payload up to 149 N at 50 mm centre-of-gravity distance from the yoke plate
- Recirculating ball bearing guide for torque loads up to Mx 10.25 Nm, lateral forces Fy 1130 N and Fz 1130 N
- Copper and PTFE-free, RoHS compliant
- Elastic cushioning at both ends, impact energy in end positions up to 0.7 J
- Position detection via proximity switch, G1/8 port
Applications
The DFM-40-25-P-A-KF works in handling modules, pick-and-place units and packaging machines, wherever a guided linear motion with 754 N is required. Any mounting position is possible.
