Airtac SAUD Double Rod Cylinder SAUD40X185
The AirTAC Airtac SAUD Double Rod Cylinder SAUD40X185 is a genuine double-acting profile-type standard air cylinder with a Ø40mm bore and 185mm 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 SAUD40X185
The AirTAC SAUD40X185 is a double-acting, double-rod profile cylinder. A 16 mm rod protrudes from both ends of the hard-anodized aluminum extrusion, meaning both faces use the rod-side area. Output is equal in both directions, delivering 528 N each way at 0.5 MPa. The unit is shorter than an ISO 15552 cylinder of the same bore.
Because the rod exits the back, you can mount a sensor cam or drive twin tooling simultaneously. This SKU lacks a magnet, so it cannot take CMSG or DMSG switches. The 1/4" port feeds the chamber, and the Viton H seal option raises the operating ceiling to 150 C. For sizing, the safe working load is about 317 N, yielding a vertical lift capacity of roughly 27 kg with a 2:1 margin.

Where the Airtac SAUD Double Rod Cylinder SAUD40X185 Is Used
Twin Tool Transfer
Drives two opposing grippers simultaneously with identical 528 N force, keeping synchronized pick and place cycles perfectly balanced.
Anti-Rotation Edge Guide
Uses the dual rods to resist twist during web routing, holding a straightening blade steady without lateral deflection.
Dual-End Marking Press
Stamps identical part numbers on both sides of a fixture at once, using the equal thrust to ensure uniform impression depth.
Is the Airtac SAUD Double Rod Cylinder SAUD40X185 the Right Cylinder?
Choose this 40 mm bore when you need 528 N of equal push and pull force at 0.5 MPa. If you need less thrust, step down to the 32 mm bore which provides 345 N both ways. If your application requires more power, step up to the 50 mm bore which yields 825 N each way. A double rod is the right call for anti-rotation guidance or carrying twin tooling. Mounting is limited to Basic, FA flange, and LB foot brackets compatible with the AirTAC SC series. At a 185 mm stroke, side loads are minimal, but always guide the load to prevent binding. Remember this SKU has no magnet, so magnetic sensing is impossible.
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 SAUD40X185 FAQ
Because the 16 mm rod exits both ends, the force is equal in both directions: 528 N at 0.5 MPa, 739 N at 0.7 MPa, and 950 N at 0.9 MPa. The 1/4" port supplies air to these chambers.
No, this specific SKU is built without a magnet, so it cannot trigger CMSG or DMSG switches. You must mechanically trigger external limits, or select a -S variant for internal sensing.
