Description
When a load has to move without rotating and without an extra guide, the guided drive DFM-25-20-P-A-GF is the compact choice. Piston Ø 25 mm, 20 mm stroke and plain-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 121 N at 50 mm centre-of-gravity distance from the yoke plate
- Plain-bearing guide for torque loads up to Mx 4.1 Nm
- Elastic cushioning at both ends, impact energy in end positions up to 0.3 J
- Position detection via proximity switch, G1/8 port
- Corrosion resistance class CRC 1, ambient temperature -20 to 80 °C
Applications
Typical tasks include lifting and lowering components, ejecting workpieces and stop or separating functions in assembly and test stations. The 20 mm stroke and the payload of 121 N set the frame for sizing.
