Festo
161221
Flat cylinder DZF-12- -A-P-A-S2
The Festo 161221 is a double-acting industrial component featuring a 12 mm equivalent piston diameter, an adjustable stroke from 1 mm to 200 mm, and an M6 piston rod thread with a through piston rod design. This unit utilizes an oval piston for torsion protection up to a max torque of 0.1 Nm, elastic cushioning rings at both ends, and position sensing via proximity switch. Operating on compressed air per ISO 8573-1:2010 [7:4:4] within a 1.6 bar to 10 bar pressure range, it delivers a retracting theoretical force of 51 N at 6 bar across an ambient temperature range of -20 °C to 80 °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.
