Airtac SAUD Double Rod Cylinder SAUD32X250S
The AirTAC Airtac SAUD Double Rod Cylinder SAUD32X250S is a genuine double-acting profile-type standard air cylinder with a Ø32mm bore and 250mm stroke, 1/8" 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 SAUD32X250S
The AirTAC SAUD32X250S is a double-acting, double-rod profile cylinder with a 32 mm bore and 250 mm stroke. A rod exits both ends, meaning push and pull forces are identical at 345 N each way at 0.5 MPa. The extruded aluminum barrel is shorter than a standard ISO 15552 unit of the same bore. This -S model includes a piston magnet for position sensing.
Because the rear rod can carry a switch cam, you gain non-rotating anti-twist guidance for twin-tool duty. With a 1/8 inch port and M10x1.25 rod thread, it runs at 30-800 mm/s. The 345 N output yields a safe working load around 207 N, translating to a vertical lift capacity of roughly 18 kg with a 2:1 safety margin.

Where the Airtac SAUD Double Rod Cylinder SAUD32X250S Is Used
Twin-Tool Transfer
Drives two opposing pickers simultaneously so both ends load and unload parts without rotation.
Cam-Triggered Sorting
Uses the extended back rod to trip a remote mechanical switch or carry a DMSG sensor cam.
Balanced Vertical Lift
Lifts light 18 kg fixtures straight up and down with equal push and pull stability.
Is the Airtac SAUD Double Rod Cylinder SAUD32X250S the Right Cylinder?
Choose this 32 mm bore delivering 345 N equal force both ways when you need synchronized motion or back-end sensing. Step up to the 40 mm bore for 528 N, or down if a smaller footprint fits. Mounting uses SC-series FA flange or LB foot brackets only. The -S magnet supports CMSG, DMSG, or EMSG switches. For this 250 mm stroke, ensure external guide rails to prevent side-load binding.
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 SAUD32X250S FAQ
Force is equal both ways because of the double rod: 345 N at 0.5 MPa, 483 N at 0.7 MPa, and 621 N at 0.9 MPa. It uses a 1/8 inch port.
No, the air cushion only decelerates near stroke end. For load holding on air loss, install an external rod lock or pilot-operated check valve.
