Product Description

What this part is

Festo ADN-63-25-A-P-A compact pneumatic cylinder. Manufacturer: Festo. Part Number: ADN-63-25-A-P-A. Festo Part No.: 536335. Series: ADN, compact cylinders to ISO 21287. Bore: 63 mm. Stroke: 25 mm. Cylinder Action: double-acting. Force at 6 bar: 1,870 N (420 lbf). Operating Pressure: 0.6 to 10 bar (8.7 to 145 psi). Ambient Temperature: -20 to +80 °C (-4 to +176 °F). Cushioning: flexible cushioning rings and pads at both ends. Piston: magnetic, for position sensing. Piston Rod Thread Form: male, external thread. Body Material: aluminium. Mounting Position: any. Country of Origin: Germany.

Decoding the order code

ADN is Festo’s compact cylinder family built to ISO 21287. The 63 is the bore in millimetres and the 25 is the stroke in millimetres. The first A is the piston rod with a male external thread. P is the cushioning code for flexible cushioning rings and pads at both ends. The final A is the magnetic piston. Bore: 63 mm. Stroke: 25 mm.

What these specs mean in practice

Force at 6 bar: 1,870 N, which is the extend force a 63 mm piston develops on a normal 6 bar shop supply — the number a designer sizes a clamp, a press or a gate against. Operating Pressure: 0.6 to 10 bar. The 0.6 bar lower limit means the cylinder still strokes on a low-pressure or decaying supply, and the 10 bar ceiling gives headroom on a regulated 6 bar line. Bore: 63 mm on a 25 mm Stroke. ISO 21287 geometry takes up to half the installation length of a comparable ISO 15552 cylinder of the same bore, so the same force fits a shorter envelope. Cushioning: flexible cushioning rings and pads at both ends absorb the end-of-stroke impact within the cylinder, which keeps the shock out of the mounting and the machine frame at speed. Piston: magnetic — the piston carries a permanent magnet, so a proximity sensor clamped to the outside of the barrel reads end-of-stroke position through the aluminium wall and reports it to the controller. Ambient Temperature: -20 to +80 °C. Body Material: aluminium. Mounting Position: any, so the cylinder is not orientation-restricted.

Quantity and configuration

Unit Quantity: 1 Pc. One cylinder, with 8 mm 90° push-to-connect fittings fitted to the ports.

Interchange guidance

Within the ADN-63-25 size, the execution letters decide the part. ADN-63-25-A-P-A is Festo 536335 with the male piston rod thread; ADN-63-25-I-P-A is Festo 536345 with the female thread in the same envelope, so the two share bore, stroke and force but present a different rod interface. ADN-63-25-A-PPS-A substitutes self-adjusting pneumatic cushioning for the flexible rings. Searchable variants of the number: ADN-63-25-A-P-A, ADN6325APA, ADN 63 25 A P A, ADN-63-25-APA, ADN63-25-A-P-A, 536335.
