Airtac SAUD Double Rod Cylinder SAUD40X280S
The AirTAC Airtac SAUD Double Rod Cylinder SAUD40X280S is a genuine double-acting profile-type standard air cylinder with a Ø40mm bore and 280mm 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 SAUD40X280S
The AirTAC SAUD40X280S is a double-acting, double-rod profile cylinder. A 16mm rod exits both ends, meaning the push and pull forces are identical at 528 N each way when operating at 0.5 MPa. The unit features a 1/4" port and an M12x1.25 rod thread. Because it uses an extruded aluminium profile barrel, this model is noticeably shorter than an ISO 15552 cylinder of the same bore.
This SKU includes the -S magnet option, allowing you to mount CMSG, DMSG, or EMSG switches directly onto the body for position sensing. For design planning, the computed safe working load is approximately 317 N (about 60% of the 528 N figure), which translates to a vertical lift capacity of roughly 27 kg with a 2:1 safety margin. You can also specify Viton H seals to raise the operating temperature limit from +70 C up to 150 C.

Where the Airtac SAUD Double Rod Cylinder SAUD40X280S Is Used
Twin-Tool Transfer
Drives two synchronized pick-and-place heads from one cylinder body, ensuring parallel tool movement without phase delay.
Anti-Rotation Lift
Lifts delicate electronics trays using the dual rods to prevent piston twist, maintaining strict vertical alignment.
Cam-Triggered Cutting
Uses the extended back rod to trip an external limit switch, confirming blade position before the primary tool strokes.
Is the Airtac SAUD Double Rod Cylinder SAUD40X280S the Right Cylinder?
When sizing this double-rod unit, consider the neighbouring bores: the 32mm version yields 345 N both ways, while the 63mm provides 1402 N. The 40mm bore here outputs 528 N each way at 0.5 MPa. Choose this twin-rod architecture when your mechanism requires strict anti-rotation guidance, needs to drive two tools simultaneously, or benefits from mounting a sensor cam on the back rod. Mounting options are limited to Basic, FA flange, and LB foot brackets, matching the AirTAC SC series footprint. Because the stroke is 280mm, ensure you use external guide rails to prevent side-load binding. The included -S magnet enables electronic position tracking.
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 SAUD40X280S FAQ
Because both faces have the same rod area, the force is equal in both directions: 528 N at 0.5 MPa, 739 N at 0.7 MPa, and 950 N at 0.9 MPa.
No, the air cushions only decelerate the piston near the stroke ends; they do not lock the load. You must add an external rod lock or pilot-operated check valve to hold a load safely.
