Airtac SAUD Double Rod Cylinder SAUD40X230
The AirTAC Airtac SAUD Double Rod Cylinder SAUD40X230 is a genuine double-acting profile-type standard air cylinder with a Ø40mm bore and 230mm stroke, 1/4" 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 SAUD40X230
The AirTAC SAUD40X230 is a double-acting, double-rod profile cylinder. A 16 mm rod protrudes from both ends, meaning push and pull forces are identical at 528 N each way at 0.5 MPa. The extruded aluminum barrel keeps the unit shorter than an ISO 15552 cylinder of the same bore. It features a 1/4" port and M12x1.25 rod threads.
This configuration provides non-rotating anti-twist guidance and allows driving two tools at once. The computed safe working load is about 317 N (60% of the 0.5 MPa force), translating to a vertical lift capacity of roughly 27 kg with a 2:1 safety margin. A high-temperature Viton H seal option extends operation to 150 C. This specific SKU lacks a magnet, so it cannot accept CMSG or DMSG sensors.

Where the Airtac SAUD Double Rod Cylinder SAUD40X230 Is Used
Twin-Tool Transfer
Drives two parallel pick-and-place heads from one piston, keeping cycle phases perfectly synchronized without adding a second valve.
Balanced Vertical Lift
Raises and lowers a 27 kg fixture with equal force both ways, preventing gravity-induced drift during downward travel.
Anti-Rotation Clamp
Holds a workpiece flat against a machining bed using the dual rods to resist torsional twist during milling operations.
Is the Airtac SAUD Double Rod Cylinder SAUD40X230 the Right Cylinder?
Choose this 40 mm bore (528 N both ways) if your application requires synchronized motion or anti-rotation guidance. Sizing up to the 50 mm bore yields 825 N, while stepping down to the 32 mm bore provides 345 N. Mounting is limited to Basic, FA flange, and LB foot styles, matching the AirTAC SC series. For this 230 mm stroke, ensure external guide rails carry any lateral load to prevent rod binding. Because this plain cylinder has no magnet, you cannot mount position switches; add a -S suffix SKU if rear cam sensing is needed.
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 SAUD40X230 FAQ
The force is equal in both directions because both faces use the rod-side area. It outputs 528 N at 0.5 MPa, 739 N at 0.7 MPa, and 950 N at 0.9 MPa. The 1/4" port supplies air to both chambers.
No. A plain SAUD cylinder drifts on air loss; the adjustable 21 mm cushions only decelerate near stroke end, they do not lock. For suspended loads, install an external rod lock or pilot-operated check valve.
