Name: Festo 194271 Flat cylinder DZF-2 1/2"-8"-A-P-A
Brand: Festo

Flat cylinder DZF-2 1/2"-8"-A-P-A

The Festo 194271 is a double-acting industrial component featuring an 8-inch stroke and a 2 1/2-inch piston diameter with an oval piston for anti-torsion guidance limiting rotation to +/- 0.4 degrees. Built with an aluminum cover, FPM and TPE-U(PU) seals, and elastic cushioning rings at both ends, this unit operates within a pressure range of 1 bar to 10 bar utilizing compressed air per ISO 8573-1:2010 [7:4:4]. It delivers a theoretical force of 1682 N retracting and 1870 N advancing at 6 bar, featuring a 1/4 NPT pneumatic connection and a moderate corrosion resistance class rating of CRC 2.

Why 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.

Engineering context

Identification and RFQ Guidance

Confirm the exact configuration

Use the manufacturer part number and model code—not appearance alone. Connection, size, material, voltage, pressure, seal, and control options can differ within the same product family.

What to include in your RFQ

Provide quantity, delivery country and ZIP/postal code, required condition, target date, and photographs of the existing nameplate when available.
