Airtac SAUD Double Rod Cylinder SAUD40X200S
The AirTAC Airtac SAUD Double Rod Cylinder SAUD40X200S is a genuine double-acting profile-type standard air cylinder with a Ø40mm bore and 200mm 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 SAUD40X200S
The AirTAC SAUD40X200S is a double-acting profile-type cylinder featuring a 40mm bore and 200mm stroke. Because a 16mm rod exits both ends, the push and pull forces are identical, delivering 528 N each way at 0.5 MPa. The extruded aluminum barrel makes it shorter than an ISO 15552 unit of the same size, and it uses a 1/4" port with M12x1.25 rod threads.
This SAUD40X200S variant includes a built-in piston magnet (-S) for direct mounting of CMSG, DMSG, or EMSG switches. The twin-rod geometry provides excellent anti-rotation stability and lets you mount a sensor cam on the back rod. Based on the 528 N output, the computed safe working load is roughly 317 N, which translates to a vertical lift capacity of about 27 kg with a 2:1 safety margin.

Where the Airtac SAUD Double Rod Cylinder SAUD40X200S Is Used
Twin-Tool Transfer
Drives two synchronized pick-and-place grippers from one piston, ensuring perfectly matched timing without independent cylinder drift.
Balanced Vertical Lift
Raises and lowers a 27 kg packaging hopper with identical push and pull thrust, preventing sagging or uneven deceleration at stroke ends.
Cam-Triggered Sorting
Uses the protruding back rod to trip an external mechanical limit switch, providing a hard physical backup to the built-in magnetic sensors.
Is the Airtac SAUD Double Rod Cylinder SAUD40X200S the Right Cylinder?
Select this 40mm bore model when your application demands equal force in both directions, superior anti-twist guidance, or synchronized twin-tool driving. If you need more power, the 50mm bore delivers 825 N each way at 0.5 MPa; for lighter duties, the 32mm bore provides 345 N. Mounting is limited to Basic, FA flange, and LB foot styles, matching the AirTAC SC series. The included -S magnet allows solid state or reed sensing. For this 200mm stroke, ensure external load guides are used 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 SAUD40X200S FAQ
Because this is a double-rod cylinder, the force is equal in both directions. It provides 528 N at 0.5 MPa, 739 N at 0.7 MPa, and 950 N at 0.9 MPa. The 1/4" port and 21mm adjustable cushions handle speeds of 30-800 mm/s.
No, the air cushions only decelerate the piston near the end of travel; they do not lock the position. To prevent drift on air loss, you must add an external rod lock or a pilot-operated check valve.
