Airtac SAUD Double Rod Cylinder SAUD63X900
The AirTAC Airtac SAUD Double Rod Cylinder SAUD63X900 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.

About the Airtac SAUD Double Rod Cylinder SAUD63X900
The AirTAC SAUD63X900 is a double-acting, double-rod profile cylinder with a 63mm bore and 900mm stroke. A rod exits both ends, meaning both faces use the rod-side area and output force is equal both ways at 1402N each way at 0.5MPa. The extruded aluminium barrel is shorter than an ISO 15552 cylinder of the same bore. It uses a 3/8 inch port and an M16x1.5 rod thread.
This SKU has no magnet, so it cannot take a magnetic switch. A computed buyer insight from the 0.5MPa figure gives a safe working load of about 841N, or a vertical lift capacity of roughly 71kg with a 2:1 margin. For high heat environments, a Viton H seal option raises the operating limit to 150C.

Where the Airtac SAUD Double Rod Cylinder SAUD63X900 Is Used
Dual-Tool Transfer
Drives two synchronized clamps on a conveyor line, using the equal both-ways force to push and pull parts evenly.
Anti-Twist Lift
Lifts vertical loads up to 71kg without rotational drift, as the twin rods prevent piston twist during travel.
Guided Pressing
Applies 1402N of pressing force in a compact profile body, ideal where a shorter overall length is required.
Is the Airtac SAUD Double Rod Cylinder SAUD63X900 the Right Cylinder?
When sizing both ways, this 63mm bore gives 1402N both ways at 0.5MPa. Stepping down, the 50mm bore yields 825N both ways. Stepping up, the 80mm bore yields 2268N both ways. Choose a double rod for anti-rotation guidance, driving twin tooling, or carrying a cam on the back rod. Mounting is limited to Basic, FA, and LB types matching the AirTAC SC series. Because the 900mm stroke is long, use external guides to prevent rod bending under side loads. Note this SKU lacks the -S magnet, so it cannot accept sensors.
Quick checklist
- ✓ Required force at your working pressure
- ✓ Stroke and mounting space
- ✓ Port/thread type (PT/G)
- ✓ Magnet (-S) for sensors?
- ✓ Side load — consider a guided cylinder
Installation & Maintenance Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.15 – 1.0 MPa operating pressure.
- check Avoid side load on the piston rod.
- check Adjust end cushion screws for smooth stops.
- check Use correct mounting accessory (FA/FB/CA/CB/LB — same as SC).
- check Installation by qualified personnel per AirTAC docs.
Airtac SAUD Double Rod Cylinder SAUD63X900 FAQ
The force is equal both ways because both ends carry a rod. It outputs 1402N at 0.5MPa, 1962N at 0.7MPa, and 2523N at 0.9MPa.
No, the air cushion only decelerates near the stroke end. For load holding on air loss, use an external rod lock or pilot-operated check valve.
