Description
Where a bare piston rod cannot take side loads, the DFM-50-25-P-A-GF-F1A guided drive steps in with 25 mm stroke and 1178 N advancing force at 6 bar.
Benefits
- Plain-bearing guide: guide rods in plain bearings, transverse force Fy up to 1533 N
- Force: 1178 N advance and 1057 N return at 6 bar (theoretical)
- Speed: up to 0.6 m/s
- Cushioning: elastic cushioning rings at both ends, impact energy up to 1 J
- Moments: Mx up to 84.33 Nm, My/Mz up to 38.33 Nm
- Battery production: reduced Cu/Zn/Ni content (F1a)
Applications
Typical uses of the DFM-50-25-P-A-GF-F1A are ejecting, separating and lifting on conveyor lines and in fixtures. Operating medium for the DFM-50-25-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. For electronics, precision or battery production, this 50 mm version offers cleanroom class 6 to ISO 14644-1 and reduced Cu/Zn/Ni content for lithium-ion battery production (F1a).
