Brand: Festo

Guided drive DFM-20-50-P-A-KF-F1A

This Festo industrial component, part number 8118854, is a double-acting guide drive unit featuring a 20 mm piston diameter, a 50 mm stroke, and a yoke drive unit operating mode with the center of gravity of the payload to the yoke plate xs at 50 mm. Equipped with recirculating ball bearing guides, elastic cushioning rings or pads at both ends, and position sensing via proximity switch, the unit operates at pressures from 0.2 MPa to 1 MPa (2 bar to 10 bar) and a maximum speed of 0.8 m/s using compressed air as per ISO 8573-1:2010 [7:4:4]. It features VDMA24364-B1/B2-L LABS conformity, ISO 14644-1 cleanroom suitability of Class 6, and suitability for Li-ion battery production with reduced Cu/Zn/Ni values (F1a) while excluding specific metals with copper, zinc, or nickel by mass as the main constituent.

Why no listed price?

Industrial and obsolete parts are priced per enquiry: the final price depends on available stock, condition, quantity, and your delivery destination, so a fixed list price would be misleading.
