Festo

177971

Profile cylinder DNC-2 1/2"-1"-PPV-A

The Festo 177971 is a double-acting industrial component featuring a 2 1/2" piston diameter, a 1" stroke, and a 5/8-18 UNF-2A male piston-rod thread built on the ISO 15552 standard. This profile barrel design operates within a pressure range of 0.06 to 1.2 MPa (0.6 to 12 bar) using compressed air conforming to ISO 8573-1:2010 [7:4:4] and includes adjustable pneumatic cushioning at both ends (PPV) with a 22 mm cushioning length. Engineered for any assembly position with provisions for proximity sensor position detection, the unit withstands ambient temperatures from -20 to 80 °C and moderate corrosion stress (CRC 2).

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.
