Description
Where a bare piston rod cannot take side loads, the DFM-16-50-P-A-KF-F1A guided drive steps in with 50 mm stroke and 121 N advancing force at 6 bar.
Benefits
- Recirculating ball bearing guide: guide rods in recirculating ball bushings, transverse force Fy up to 778 N
- Force: 121 N advance and 90 N return at 6 bar (theoretical)
- Speed: up to 0.8 m/s
- Cleanroom and PWIS: class 6 to ISO 14644-1, PWIS-free to VDMA24364-B1/B2-L
- Piston rod: high-alloy stainless steel
- Battery production: reduced Cu/Zn/Ni content (F1a)
Applications
Typical jobs for the DFM-16-50-P-A-KF-F1A are precise lifting, pushing and positioning in assembly and handling systems. The DFM-16-50-P-A-KF-F1A runs on compressed air to ISO 8573-1:2010 [7:4:4] at -5 to 60 °C ambient temperature and can be mounted in any position. For electronics, precision or battery production, this 16 mm version offers cleanroom class 6 to ISO 14644-1 and reduced Cu/Zn/Ni content for lithium-ion battery production (F1a).
