Airtac SAUD Double Rod Cylinder SAUD40X100S
The AirTAC Airtac SAUD Double Rod Cylinder SAUD40X100S is a genuine double-acting profile-type standard air cylinder with a Ø40mm bore and 100mm 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 SAUD40X100S
The AirTAC SAUD40X100S is a double-acting, double-rod profile cylinder. A 16 mm rod exits both ends of the hard-anodized extruded aluminum barrel, meaning both faces use the rod-side piston area. This yields exactly 528 N of output force at 0.5 MPa in both directions. The 1/4" port and integrated magnet for CMSG/DMSG/EMSG switches are standard.
Because the rod protrudes at the back, you can mount a sensor cam or trip a switch externally. This unit is shorter than an ISO 15552 cylinder of the same bore. For sizing, the safe working load is roughly 317 N (about 60 percent of the 528 N figure), which translates to a vertical lift capacity of about 27 kg with a 2:1 safety margin.

Where the Airtac SAUD Double Rod Cylinder SAUD40X100S Is Used
Twin Tool Transfer
Drives two parallel pick-and-place heads simultaneously with equal 528 N force, preventing yaw during rapid horizontal transfers.
Anti-Rotation Lift
Lifts 27 kg vertical loads using the dual rods to resist twist, keeping the payload perfectly aligned without external linear bearings.
Rear Cam Sensing
Uses the back rod extension to physically trip a limit switch or carry a CMSG magnetic sensor for precise end-of-stroke confirmation.
Is the Airtac SAUD Double Rod Cylinder SAUD40X100S the Right Cylinder?
Choose this 40 mm bore when you need 528 N of equal push and pull force at 0.5 MPa. If your project requires less thrust, the 32 mm bore provides 345 N both ways; for heavier loads, the 50 mm bore offers 825 N. A double-rod design is the right call for anti-rotation guidance, driving twin tooling, or mounting a rear sensor cam. Mounting hardware is compatible with AirTAC SC series FA flange and LB foot brackets. The -S suffix means a piston magnet is installed for electronic or reed switches. For this 100 mm stroke, ensure external guides support any 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 SAUD40X100S FAQ
The force is equal in both directions because the 16 mm rod exits both ends. It outputs 528 N at 0.5 MPa, 739 N at 0.7 MPa, and 950 N at 0.9 MPa.
No, a plain double-rod cylinder drifts without live air; the 21 mm adjustable cushions only decelerate near stroke end. Use an external rod lock or pilot-operated check valve for secure load holding.
