Description
Where a bare piston rod cannot take side loads, the DFM-20-20-P-A-GF-F1A guided drive steps in with 20 mm stroke and 188 N advancing force at 6 bar.
Benefits
- Plain-bearing guide: guide rods in plain bearings, transverse force Fy up to 354.7 N
- Force: 188 N advance and 141 N return at 6 bar (theoretical)
- Cleanroom and PWIS: class 6 to ISO 14644-1, PWIS-free to VDMA24364-B1/B2-L
- Moments: Mx up to 10.29 Nm, My/Mz up to 3.37 Nm
- Speed: up to 0.8 m/s
- Cushioning: elastic cushioning rings at both ends, impact energy up to 0.2 J
Applications
The DFM-20-20-P-A-GF-F1A suits lifting, stopping and pushing tasks in conveyor systems and fixture building. Operating medium for the DFM-20-20-P-A-GF-F1A is compressed air to ISO 8573-1:2010 [7:4:4], permitted ambient temperature -20 to 80 °C, any mounting position. Documented for this 20 mm stroke version: cleanroom class 6 to ISO 14644-1 and reduced Cu/Zn/Ni content for lithium-ion battery production (F1a).
