Festo
170919
Guided drive DFM-20-50-P-A-KF
The Festo 170919 is a double-acting industrial drive unit featuring a 20 mm piston diameter and a 50 mm stroke, operating via a yoke drive mode with elastic cushioning rings or pads at both ends. Designed with a recirculating ball bearing guide and accommodating any mounting position, this component handles an operating pressure range of 0.2 MPa to 1 MPa (2 bar to 10 bar) and achieves a maximum speed of 0.8 m/s with a max force Fy of 817 N. Position sensing is accomplished via proximity switch, and the unit operates using compressed air as per ISO 8573-1:2010 [7:4:4] within an ambient temperature range of -5 °C to 60 °C.

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.
