Guided drive DFM-20-25-P-A-KF-F1A

The Festo part number 8118851 is an industrial guide drive unit featuring a 20 mm piston diameter, a 25 mm stroke, and a yoke drive operating mode with a recirculating ball bearing guide. This double-acting component operates on compressed air within a pressure range of 0.2 MPa to 1 MPa (2 bar to 10 bar) and supports a maximum speed of 0.8 m/s, utilizing elastic cushioning rings or pads at both ends. Designed with any mounting position and position sensing via proximity switch, the unit meets VDMA24364-B1/B2-L LABS conformity and ISO 14644-1 cleanroom class 6 standards 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.
