Airtac SAUD Double Rod Cylinder SAUD100X40S
The AirTAC Airtac SAUD Double Rod Cylinder SAUD100X40S is a genuine double-acting profile-type standard air cylinder with a Ø100mm bore and 40mm stroke, 1/2" 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 SAUD100X40S
The AirTAC SAUD100X40S is a double-acting, double-rod profile cylinder. A Ø25 mm rod protrudes from both ends of the hard-anodized aluminum extrusion, meaning both faces use the identical rod-side area. This yields equal push and pull force of 3681 N each way at 0.5 MPa. The 1/2 inch port feeds the 100 mm bore, operating at 30-800 mm/s.
This compact profile body is notably shorter than an ISO 15552 unit of the same bore, with mounting compatible only to the AirTAC SC series via FA or LB brackets. The included -S piston magnet enables CMSG, DMSG or EMSG switches on the rear rod for end-of-stroke confirmation.

Theoretical Output Force (Ø100mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 3682 N | 3682 N |
| 0.7 MPa | 5154 N | — |
| Max (@1.0 MPa) | 751 kgf | |
Double-rod model: the rod passes through the rear cover, so both piston faces lose rod area and push is shown at the annular-area value. Actual usable force is lower than theoretical due to friction and back-pressure. Size with a safety margin.

Where the Airtac SAUD Double Rod Cylinder SAUD100X40S Is Used
Twin-Tool Machining
Drives opposing machining heads simultaneously with perfectly balanced 3681 N force on both faces for synchronized part processing.
Dual Transfer Pusher
Pushes workpieces to either side of a conveyor line using a single compact actuator, saving space over two separate cylinders.
Rear-Cam Sensing
Uses the extended back rod to trip a CMSG or DMSG switch directly, providing precise position feedback in tight cells.
Is the Airtac SAUD Double Rod Cylinder SAUD100X40S the Right Cylinder?
Choose this 100 mm bore when your application demands identical 3681 N thrust in both directions, such as driving twin opposing tools or carrying a sensor cam on the back rod. If you need less force, step down to the 80 mm bore which provides 2268 N each way. If you require more, note that 100 mm is the largest standard SAUD bore available. The -S magnet is essential if you need position sensing. For this 40 mm stroke, side-load is minimal, but any stroke over 300 mm requires external guide rails to prevent binding. Remember this cylinder will not hold a load without live air; use a pilot-operated check valve for vertical holding.
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 SAUD100X40S FAQ
Because the 25 mm rod exits both ends, the force is equal in both directions. It delivers 3681 N at 0.5 MPa, 5153 N at 0.7 MPa, and 6626 N at 0.9 MPa.
No, the adjustable 29 mm air cushions only decelerate the piston near stroke end. For load holding on air loss, you must install an external rod lock or pilot-operated check valve.
