Festo
8118918
Guided drive DFM-40-125-P-A-KF-F1A
This Festo industrial component, part number 8118918, is a double-acting drive unit featuring a yoke structural design, a 40 mm piston diameter, and a 125 mm stroke with a recirculating ball bearing guide. It operates with compressed air according to ISO 8573-1:2010 [7:4:4] at pressures from 0.15 MPa to 1 MPa (1.5 bar to 10 bar), achieving a maximum speed of 0.8 m/s with elastic cushioning rings or pads at both ends and position sensing via proximity switch. The unit includes any mounting position, an ambient temperature range of -5 °C to 60 °C, a 50 mm distance of the center of gravity of the payload to the yoke plate xs, and compliance with VDMA24364-B1/B2-L LABS conformity for reduced Cu/Zn/Ni battery production and ISO 14644-1 Class 6 cleanroom standards.
