The AirTAC Airtac SAUD Double Rod Cylinder SAUD63X900S is a genuine double-acting profile-type standard air cylinder with a Ø63mm bore and 900mm stroke, 3/8" air ports and adjustable end cushioning. Its hard-anodized aluminum-profile barrel is shorter than an ISO 15552 cylinder of the same bore, and it shares SC-series mounting accessories.
The AirTAC SAUD63X900S is a double-acting, double-rod profile cylinder. A rod exits both ends, meaning both faces use the rod-side area and push and pull force are equal at 1402 N each way at 0.5 MPa. The extruded aluminium profile barrel is shorter than an ISO 15552 cylinder of the same bore. It features a 3/8 inch port and an M16x1.5 rod thread.
This 900 mm stroke unit includes a built-in piston magnet (-S) for CMSG, DMSG, or EMSG switches. The adjustable air cushion is 21 mm at each end. For sizing, a safe working load is roughly 841 N (about 60 percent of the 0.5 MPa figure), yielding a vertical lift capacity of about 71 kg with a 2:1 margin. A Viton H seal option raises the operating temperature to 0-150 C.

Related SAU-family variants: SAUD (double rod), SAUJ (adjustable stroke), SAUF (with built-in solenoid valve), and SAU-S with built-in magnet. Seals: TPU (blank) / Viton H / NBR N. Sensor switches: CMSG / DMSG / EMSG.
Drives two parallel pick-and-place arms from one piston, keeping motion perfectly synchronized without twisting.
Uses the protruding back rod to physically trip a limit valve or carry a switch cam in tight machinery.
Lifts and lowers dual machining spindles with equal push and pull force, preventing binding on long 900 mm moves.
When sizing this double-rod unit, compare both ways: the 50 mm bore yields 825 N, while the 80 mm bore yields 2268 N at 0.5 MPa. Choose this 63 mm model when you need anti-rotation guidance, twin tooling, or back-end sensing. Mounting is limited to Basic, FA, and LB types, matching the AirTAC SC series. Because the stroke is 900 mm, you must use external guides to prevent rod bending under side loads. The -S magnet allows position sensing.
Quick checklist
The force is equal both ways because both faces use the rod-side area. It outputs 1402 N at 0.5 MPa, 1962 N at 0.7 MPa, and 2523 N at 0.9 MPa.
No, a plain cylinder drifts on air loss; the 21 mm cushion only decelerates near stroke end. For a held load, install an external rod lock or pilot-operated check valve.
