Airtac SAUD Double Rod Cylinder SAUD40X170S
The AirTAC Airtac SAUD Double Rod Cylinder SAUD40X170S is a genuine double-acting profile-type standard air cylinder with a Ø40mm bore and 170mm 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 SAUD40X170S
The AirTAC SAUD40X170S 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 area. This yields equal push and pull force of 528 N each way at 0.5 MPa. The 1/4" port and M12x1.25 rod thread are fixed by the 40 mm bore.
Because the extruded profile omits external rods, it is shorter than an ISO 15552 cylinder of the same bore. The -S suffix adds a piston magnet for CMSG, DMSG, or EMSG switches. A computed buyer insight: safe working load is roughly 317 N (about 60% of the 528 N figure), and vertical lift is about 27 kg with a 2:1 margin. Viton H seals can raise the operating temperature to 150 C.

Where the Airtac SAUD Double Rod Cylinder SAUD40X170S Is Used
Twin-Tool Transfer
Drives two synchronized pick-and-place grippers from one piston, ensuring parallel tool movement without adding a second actuator.
Anti-Rotation Edge Guide
Uses the twin rods to resist twist during web handling, keeping a paper or film edge guide perfectly straight without external linear bearings.
Rear-Cam Sensing
Mounts a switch trip cam on the back rod extension, freeing the front workspace for direct part contact while confirming stroke completion.
Is the Airtac SAUD Double Rod Cylinder SAUD40X170S the Right Cylinder?
Size both ways: the 32 mm bore yields 345 N each way at 0.5 MPa, while the 50 mm bore yields 825 N. Choose this 40 mm double-rod model when you need anti-rotation guidance, twin tooling, or a back rod to carry a sensor cam. Mounting is limited to Basic, FA flange, and LB foot styles, matching the AirTAC SC series. The 170 mm stroke is under 300 mm, so side-load guide rules are relaxed, but always support external bearings for heavy radial loads. The -S magnet enables position 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 SAUD40X170S FAQ
Force is equal both ways because a rod exits both ends. It generates 528 N at 0.5 MPa, 739 N at 0.7 MPa, and 950 N at 0.9 MPa. The 1/4" port feeds both chambers equally.
No, a plain SAUD cylinder drifts without live air; the 21 mm adjustable cushions only decelerate near stroke end. For true load holding, install an external rod lock or pilot-operated check valve.
