Description

At 6 bar the DFM-25-80-P-A-KF-F1A turns a theoretical 295 N into a guided linear motion over 80 mm, with a 25 mm piston.

Benefits

  • Recirculating ball bearing guide: guide rods in recirculating ball bushings, transverse force Fy up to 863 N
  • Force: 295 N advance and 247 N return at 6 bar (theoretical)
  • Piston rod: high-alloy stainless steel
  • Moments: Mx up to 29.35 Nm, My/Mz up to 16.83 Nm
  • Cushioning: elastic cushioning rings at both ends, impact energy up to 0.3 J
  • Cleanroom and PWIS: class 6 to ISO 14644-1, PWIS-free to VDMA24364-B1/B2-L

Applications

Use the DFM-25-80-P-A-KF-F1A where smooth travel and accurate guidance matter for lifting, joining or ejecting parts. Operating medium for the DFM-25-80-P-A-KF-F1A is compressed air to ISO 8573-1:2010 [7:4:4], permitted ambient temperature -5 to 60 °C, any mounting position. For electronics, precision or battery production, this 25 mm version offers cleanroom class 6 to ISO 14644-1 and reduced Cu/Zn/Ni content for lithium-ion battery production (F1a).
