Description
When a load has to move without rotating and without an extra guide, the guided drive DFM-25-80-P-A-KF is the compact choice. Piston Ø 25 mm, 80 mm stroke and recirculating ball bearing guide are combined in a housing made of wrought aluminium alloy.
Benefits
- 295 N advance force and 247 N on the return stroke at 6 bar, piston Ø 25 mm
- Payload up to 95 N at 50 mm centre-of-gravity distance from the yoke plate
- Recirculating ball bearing guide for torque loads up to Mx 4.33 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
The DFM-25-80-P-A-KF works in handling modules, pick-and-place units and packaging machines, wherever a guided linear motion with 295 N is required. Any mounting position is possible.
