Airtac SAUD Double Rod Cylinder SAUD32X40S
The AirTAC Airtac SAUD Double Rod Cylinder SAUD32X40S is a genuine double-acting profile-type standard air cylinder with a Ø32mm bore and 40mm 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 SAUD32X40S
The AirTAC SAUD32X40S is a double-acting, double-rod profile cylinder. A 12 mm rod exits both ends of the hard-anodized aluminum extruded barrel, meaning both faces use the rod-side piston area. This yields identical push and pull thrust of 345 N each way at 0.5 MPa. The extruded profile makes it shorter than an ISO 15552 cylinder of the same 32 mm bore.
Because the -S suffix denotes a built-in piston magnet, this model directly supports CMSG, DMSG, and EMSG electronic or reed switches. The 1/8 inch port feeds a 30-800 mm/s speed range, while adjustable 21 mm air cushions decelerate the stroke at both ends. For sizing, the 345 N output at 0.5 MPa translates to a safe working load of roughly 207 N, or a vertical lift capacity of about 18 kg with a 2:1 safety margin.

Where the Airtac SAUD Double Rod Cylinder SAUD32X40S Is Used
Twin-Tool Transfer
Drives two opposing pick-and-place grippers simultaneously from one compact body, ensuring perfectly synchronized part handover without twist.
Cam-Driven Sensing
Uses the protruding back rod to physically trip a CMSG or DMSG limit switch, providing a hard mechanical position confirmation independent of internal magnets.
Anti-Rotation Pinning
Executes short 40 mm clamping or pinning strokes where the dual rod geometry prevents the end effector from twisting under offset loads.
Is the Airtac SAUD Double Rod Cylinder SAUD32X40S the Right Cylinder?
Select this 32 mm bore unit when a task demands equal 345 N thrust in both directions, such as twin-tool machining or non-rotating anti-twist guidance. If your project needs less force, step down is not available below 32 mm in this series; if you need more power, step up to the 40 mm bore which provides 528 N each way at 0.5 MPa. Mounting is limited to Basic, FA flange, and LB foot styles, matching the AirTAC SC series. The included -S magnet allows back-end switch sensing on the rear rod. At a 40 mm stroke, side loads are minimal, but always use external guide rails for any stroke reaching 300 mm or more.
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 SAUD32X40S FAQ
Because it is a double-rod cylinder, the force is equal in both directions: 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 and a 12 mm rod on both faces.
No, a plain double-rod cylinder drifts when air is lost or the valve is centered. The adjustable 21 mm cushions only decelerate the piston near the stroke ends; they do not lock. Use an external rod lock or pilot-operated check valve for secure load holding.
