Festo
8118865
Guided drive DFM-25-40-P-A-GF-F1A
The Festo 8118865 is a double-acting industrial drive unit featuring a 25 mm piston diameter, a 40 mm stroke, and a yoke operating mode with a plain-bearing guide. It operates with compressed air within a pressure range of 0.15 MPa to 1 MPa (1.5 bar to 10 bar) at a maximum speed of 0.8 m/s, utilizing elastic cushioning rings or pads at both ends and position sensing via proximity switch. This component accommodates any mounting position, an ambient temperature range of -20 °C to 80 °C, and a payload centre of gravity distance to the yoke plate xs of 50 mm, while meeting ISO 14644-1 cleanroom Class 6 and VDMA24364-B1/B2-L LABS conformity standards with copper, zinc, and nickel restrictions.

Request a QuoteWhy 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. Request a quote and we confirm current pricing, lead time, and sourcing options — including hard-to-find and discontinued Festo references — within one business day.
