Festo
161256
Flat cylinder DZF-25-125-A-P-A
The Festo 161256 is a double-acting industrial component featuring a 25 mm piston diameter, a 125 mm stroke, and an M10x1.25 piston rod thread with an oval piston providing torsion protection up to a 0.5 Nm max torque and a +/- 1 degree rotation angle. Operating on compressed air within a 1 bar to 10 bar pressure range and a -20 ÞgC to 80 ÞgC ambient temperature span, this unit incorporates elastic cushioning rings at both ends, position sensing via proximity switch, and delivers a theoretical retracting force of 247 N at 6 bar. It has a CRC rating of 2 for moderate corrosion stress, conforms to VDMA24364-B1/B2-L LABS standards, and permits oil lubrication.

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.
