Airtac SAUD Double Rod Cylinder SAUD40X900
The AirTAC Airtac SAUD Double Rod Cylinder SAUD40X900 is a genuine double-acting profile-type standard air cylinder with a Ø40mm bore and 900mm 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 SAUD40X900
The AirTAC SAUD40X900 is a double-acting, double-rod profile cylinder featuring a 40mm bore and a 900mm stroke. A rod protrudes from both ends, meaning the push and pull output is identical at 528 N each way at 0.5 MPa. The extruded aluminum barrel makes it shorter than a standard ISO 15552 unit of the same bore, and it uses a 1/4 inch port with an M12x1.25 rod thread.
Because this SKU lacks the -S magnet suffix, it cannot accept magnetic sensors. For sizing, the 528 N output yields a safe working load of roughly 317 N, or a vertical lift capacity of about 27 kg with a 2:1 safety margin. You can also specify Viton H seals to raise the operating ceiling from 70C up to 150C.

Where the Airtac SAUD Double Rod Cylinder SAUD40X900 Is Used
Dual-Tool Transfer
Drives two synchronized work heads from one piston, keeping timing identical across a 900mm packaging line.
Anti-Twist Lift
Lifts delicate electronics racks vertically without rotational drift, using the twin rods for inherent guidance.
Symmetric Clamping
Applies 528 N of clamping pressure from both ends simultaneously to hold a workpiece centered.
Is the Airtac SAUD Double Rod Cylinder SAUD40X900 the Right Cylinder?
Choose this 40mm bore when you need 528 N of equal bidirectional force; step down to the 32mm bore for 345 N, or up to the 50mm bore for 825 N. The twin-rod layout is ideal for anti-rotation guidance, driving dual tooling, or mounting a switch cam on the back rod. Mounting is limited to Basic, FA flange, and LB foot types, matching the AirTAC SC series. At this long 900mm stroke, you must use external guide rails to prevent rod bending and absorb side loads.
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 SAUD40X900 FAQ
The force is equal in both directions due to the double-rod design. It provides 528 N at 0.5 MPa, 739 N at 0.7 MPa, and 950 N at 0.9 MPa.
No, this specific SKU lacks the -S magnet option, so it cannot accept CMSG, DMSG, or EMSG switches. You would need the -S variant for position sensing.
