Festo
170844
Guided drive DFM-20-50-P-A-GF
This Festo industrial component features a 20 mm piston diameter, a 50 mm stroke, and a yoke drive unit operating mode with a plain-bearing guide. Operating on compressed air within a 0.2 MPa to 1 MPa pressure range, the double-acting unit achieves a maximum speed of 0.8 m/s and supports a maximum force Fy of 709.3 N. Position sensing is performed via proximity switch, while elastic cushioning rings and pads at both ends absorb an impact energy of 0.2 Nm.

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.
