Festo

571940

Compact cylinder ADNP-25-30-A-P-A

The Festo 571940 is a double-acting industrial component based on the ISO 21287 standard featuring a 25 mm piston diameter, a 30 mm stroke, and an M8 male piston rod thread. This single-ended piston rod unit incorporates flexible cushioning rings at both ends, accommodates position detection via proximity sensors, and operates on compressed air within a working pressure range of 0.6 to 10 bar. It delivers a theoretical force of 295 N on the advance stroke and 247 N on the return stroke at 6 bar while functioning across an ambient temperature range of -10 to 60 °C with a CRC 2 moderate corrosion resistance classification.

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.
