Airtac SAUD Double Rod Cylinder SAUD40X200
The AirTAC Airtac SAUD Double Rod Cylinder SAUD40X200 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 SAUD40X200
The AirTAC SAUD40X200 is a double-acting, double-rod profile cylinder. A 16 mm rod exits both ends of the hard-anodized aluminum barrel, meaning both faces use the rod-side piston area. This yields exactly 528 N of output force at 0.5 MPa in both directions. The extruded profile body is notably shorter than a standard ISO 15552 unit of the same 40 mm bore.
Because the rod protrudes at the back, you can mount a sensor cam or drive twin tooling while gaining anti-rotation stability. This non-magnet SKU cannot host CMSG or DMSG switches. The 1/4" port feeds a bore running 30-800 mm/s. A computed buyer insight: the safe working load is about 317 N, which translates to a vertical lift capacity of roughly 27 kg with a 2:1 safety margin.

Where the Airtac SAUD Double Rod Cylinder SAUD40X200 Is Used
Twin-Tool Transfer
Drives two opposing grippers simultaneously from one piston, utilizing the equal bidirectional thrust to push and pull parts evenly.
Anti-Rotation Lift
The dual-rod geometry prevents mechanical twist during vertical elevation, ensuring precise platen alignment without external guides.
Reciprocating Deflector
Alternates a sorting flap back and forth on a packaging line, relying on the matched 528 N force to consistently divert items.
Is the Airtac SAUD Double Rod Cylinder SAUD40X200 the Right Cylinder?
Choose this 40 mm bore if your application demands equal push and pull thrust, such as synchronized lifting or anti-twist guidance. It delivers 528 N both ways at 0.5 MPa. If you need less force, step down to the 32 mm bore offering 345 N; if you need more, step up to the 50 mm bore providing 825 N. Mounting is limited to Basic, FA flange, and LB foot styles, matching the AirTAC SC series. At a 200 mm stroke, side loads remain manageable, but always use external guide rails for any heavier offset payload. Note that this specific model lacks a magnet and cannot support 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 SAUD40X200 FAQ
The force is equal in both directions because both faces have a 16 mm rod. It generates 528 N at 0.5 MPa, 739 N at 0.7 MPa, and 950 N at 0.9 MPa. Never expect a larger single-rod push value from this unit.
No, a plain double-rod cylinder drifts without live air; the adjustable 21 mm cushions only decelerate near stroke end. For suspended loads, install an external rod lock or pilot-operated check valve.
