Airtac SAUD Double Rod Cylinder SAUD40X145S
The AirTAC Airtac SAUD Double Rod Cylinder SAUD40X145S is a genuine double-acting profile-type standard air cylinder with a Ø40mm bore and 145mm 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 SAUD40X145S
The AirTAC SAUD40X145S is a double-acting, double-rod profile cylinder featuring a 40 mm bore and 145 mm stroke. A rod protrudes from both ends, meaning both faces use the rod-side area to deliver an identical output of 528 N each way at 0.5 MPa. The extruded aluminum barrel is noticeably shorter than an ISO 15552 unit of the same bore. This SKU includes the -S magnet for CMSG, DMSG, or EMSG switches.
Because the rear rod extends outward, it provides a perfect surface to mount a sensor cam or trigger an external switch. Based on the 528 N output, the safe working load is approximately 317 N, and it can manage a vertical lift of about 27 kg with a 2:1 safety margin. The 1/4" port and M12x1.25 rod thread are fixed for this bore.

Where the Airtac SAUD Double Rod Cylinder SAUD40X145S Is Used
Twin-Tool Transfer
Drives two opposing grippers simultaneously to pick and place parts from both ends without rotational twist.
Cam-Triggered Cutting
Uses the protruding back rod to trip an external limit switch, confirming the blade reached full extension.
Balanced Vertical Lift
Raises a 27 kg platen evenly because the equal push and pull forces prevent sudden dropping at direction changes.
Is the Airtac SAUD Double Rod Cylinder SAUD40X145S the Right Cylinder?
Choose this 40 mm bore if your application requires anti-rotation guidance, twin tooling, or back-end sensing. It delivers 528 N both ways; step down to the 32 mm bore for 345 N, or up to the 50 mm bore for 825 N. Mounting is limited to Basic, FA flange, and LB foot, matching the AirTAC SC series. At 145 mm stroke, side loads are minimal, but always guide the load externally on longer strokes. The -S option enables electronic 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 SAUD40X145S FAQ
The force is equal in both directions because both chambers contain a rod. It provides 528 N at 0.5 MPa, 739 N at 0.7 MPa, and 950 N at 0.9 MPa.
No, a plain cylinder drifts without live air, and the adjustable 21 mm cushions only decelerate near the end of stroke. Use an external rod lock or pilot-operated check valve for secure load holding.
