Festo
161257
Flat cylinder DZF-25-160-A-P-A
The Festo part number 161257 is a double-acting industrial component featuring a 25 mm equivalent piston diameter, a 160 mm stroke, and an M10x1.25 piston rod thread with an oval piston providing torsion protection up to 0.5 Nm and a maximum rotation angle of plus or minus 1 degree. Operating on compressed air according to ISO 8573-1:2010 [7:4:4] within a 1 bar to 10 bar pressure range and an ambient temperature range of -20 °C to 80 °C, this unit delivers a theoretical retracting force of 247 N at 6 bar utilizing elastic cushioning rings at both ends and position sensing via proximity switch. It incorporates a single-end piston rod design with a moderate corrosion resistance class of 2 and VDMA24364-B1/B2-L LABS conformity, allowing operation with 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.
