Festo
8118845
Guided drive DFM-20-30-P-A-GF-F1A
The Festo part number 8118845 is a double-acting industrial guide drive unit featuring a 20 mm piston diameter, a 30 mm stroke, and a yoke operating mode with a 50 mm distance from the payload centre of gravity to the yoke plate. Designed with a plain-bearing guide, elastic cushioning rings or pads at both ends, and position sensing via proximity switch, this component operates on compressed air within a 0.2 MPa to 1 MPa pressure range and supports a maximum speed of 0.8 m/s across any mounting position. It meets ISO 14644-1 Cleanroom Class 6 standards, VDMA24364-B1/B2-L LABS conformity, and includes reduced Cu/Zn/Ni values suitable for Li-ion battery production under specific material restrictions.
