Airtac SAUD Double Rod Cylinder SAUD40X350
The AirTAC Airtac SAUD Double Rod Cylinder SAUD40X350 is a genuine double-acting profile-type standard air cylinder with a Ø40mm bore and 350mm 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 SAUD40X350
The AirTAC SAUD40X350 is a double-acting, double-rod profile cylinder. A 16mm rod exits both ends of the hard-anodized aluminum barrel, meaning both faces use the rod-side area. This yields exactly 528 N of thrust and pull at 0.5 MPa. The extruded profile body is noticeably shorter than an ISO 15552 unit of the same bore. It uses a 1/4 inch port and M12x1.25 rod threads.
Because the piston travels 350 mm, you must use external guides to prevent rod bending under side loads. This SKU lacks a magnet, so it cannot accept CMSG or DMSG switches. For sizing, a safe working load is roughly 317 N. In a vertical lift with a 2:1 safety margin, it can manage about 27 kg. Note that the end cushions only decelerate the piston; they do not hold the load if air pressure drops.

Where the Airtac SAUD Double Rod Cylinder SAUD40X350 Is Used
Twin Tool Transfer
Drives two identical pickers in perfect synchronization, using the equal both-ways force to push and pull parts simultaneously.
Anti-Rotation Stamping
Prevents piston twist during a pressing task, keeping the tool face perfectly aligned without needing external linear bearings.
Dual End Sorting
Uses the extended back rod to actuate a mechanical diverter while the front rod pushes parcels onto a secondary belt.
Is the Airtac SAUD Double Rod Cylinder SAUD40X350 the Right Cylinder?
Choose this 40mm bore if you need 528 N of equal force in both directions. Stepping up to the 50mm bore provides 825 N, while dropping down to the 32mm bore gives 345 N at 0.5 MPa. A twin-rod design is the right call when you need anti-rotation accuracy, want to drive two tools at once, or need a back rod to trip a switch. Mounting is limited to Basic, FA flange, and LB foot styles, matching the AirTAC SC series. Because this is a 350mm stroke, external linear guides are required to handle side loads and prevent rod bending. Add the -S suffix variant if you need magnetic sensing.
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 SAUD40X350 FAQ
The double-rod design provides equal force in both directions: 528 N at 0.5 MPa, 739 N at 0.7 MPa, and 950 N at 0.9 MPa. It never produces a larger single-rod push value.
No. This specific SKU does not include a magnet. You must select an SAUD40X350-S model to use CMSG, DMSG, or EMSG switches for position sensing.
