Description

At 6 bar the DFM-25-40-P-A-KF-F1A turns a theoretical 295 N into a guided linear motion over 40 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)
  • Battery production: reduced Cu/Zn/Ni content (F1a)
  • Moments: Mx up to 29.35 Nm, My/Mz up to 16.83 Nm
  • Cleanroom and PWIS: class 6 to ISO 14644-1, PWIS-free to VDMA24364-B1/B2-L
  • Speed: up to 0.8 m/s

Applications

Typical jobs for the DFM-25-40-P-A-KF-F1A are precise lifting, pushing and positioning in assembly and handling systems. The DFM-25-40-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. Documented for this 40 mm stroke version: cleanroom class 6 to ISO 14644-1 and reduced Cu/Zn/Ni content for lithium-ion battery production (F1a).
