Airtac SAUD Double Rod Cylinder SAUD40X110
The AirTAC Airtac SAUD Double Rod Cylinder SAUD40X110 is a genuine double-acting profile-type standard air cylinder with a Ø40mm bore and 110mm 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 SAUD40X110
The AirTAC SAUD40X110 is a double-acting, double-rod profile cylinder featuring a 40 mm bore and 110 mm stroke. Because a 16 mm rod protrudes from both ends, the effective piston area is identical on each face, yielding an equal force of 528 N in both directions at 0.5 MPa. The extruded hard-anodized aluminium barrel keeps the unit shorter than an ISO 15552 cylinder of the same bore, and the 1/4" port drives a swift 30-800 mm/s operating speed.
This twin-rod architecture provides inherent anti-rotation guidance and lets you mount twin tooling or a switch 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. This specific SKU lacks a magnet, so it cannot host CMSG or DMSG sensors; for high-heat environments up to 150 C, specify the Viton H seal option.

Where the Airtac SAUD Double Rod Cylinder SAUD40X110 Is Used
Twin-Spindle Pickup
Drives two synchronized grippers from one piston to lift and transfer small machined components without rotational drift.
Dual Pusher Assembly
Uses the extending front rod to index cartons while the rear rod trips a mechanical valve cam for timing control.
Non-Rotating Stamping
Holds a small marking die steady against uneven part surfaces, relying on the dual rods to prevent angular twist during impact.
Is the Airtac SAUD Double Rod Cylinder SAUD40X110 the Right Cylinder?
Select this 40 mm bore if your application requires perfectly symmetrical push and pull thrust. Sizing up to the 50 mm bore raises the equal force to 825 N at 0.5 MPa, while stepping down to the 32 mm bore drops it to 345 N. A double-rod design is the right call when you need anti-twist stability, synchronized dual-tool driving, or rear-rod cam actuation. Mounting is limited to Basic, FA flange, and LB foot styles, matching the AirTAC SC series footprint. At a 110 mm stroke, side loads are minimal, but for any stroke over 300 mm you should add external guide rails to prevent rod binding. Remember that this non-magnetic variant 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 SAUD40X110 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. It uses a 1/4" port and never quotes a larger single-rod push value.
No, a plain double-rod cylinder drifts without live air, as the adjustable cushions only decelerate near stroke end. For a suspended load, install an external rod lock or pilot-operated check valve.
