Description
When a load has to move without rotating and without an extra guide, the guided drive DFM-20-20-P-A-GF is the compact choice. Piston Ø 20 mm, 20 mm stroke and plain-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 67 N at 50 mm centre-of-gravity distance from the yoke plate
- Plain-bearing guide for torque loads up to Mx 1.85 Nm
- Elastic cushioning at both ends, impact energy in end positions up to 0.2 J
- Position detection via proximity switch, M5 port
- Corrosion resistance class CRC 1, ambient temperature -20 to 80 °C
Applications
Fields of use are assembly machines, feeding systems and test fixtures. The operating pressure of 2 to 10 bar and the M5 port suit standard compressed air networks with air treated to ISO 8573-1.
