Description
20 mm stroke, 121 N advance force at 6 bar and a recirculating ball bearing guide that keeps the load from rotating: the guided drive DFM-16-20-P-A-KF handles lifting, pushing and positioning without an additional guide.
Benefits
- 121 N advance force and 90 N on the return stroke at 6 bar, piston Ø 16 mm
- Payload up to 41 N at 50 mm centre-of-gravity distance from the yoke plate
- Recirculating ball bearing guide for torque loads up to Mx 1.79 Nm, lateral forces Fy 389 N and Fz 389 N
- Copper and PTFE-free, RoHS compliant
- Elastic cushioning at both ends, impact energy in end positions up to 0.15 J
- Position detection via proximity switch, M5 port
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 41 N set the frame for sizing.
