Airtac SAUD Double Rod Cylinder SAUD40X115
The AirTAC Airtac SAUD Double Rod Cylinder SAUD40X115 is a genuine double-acting profile-type standard air cylinder with a Ø40mm bore and 115mm 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 SAUD40X115
The AirTAC SAUD40X115 is a double-acting, double-rod profile cylinder featuring a 40 mm bore and a 115 mm stroke. Because a 16 mm rod protrudes from both ends, the push and pull forces are identical, yielding 528 N each way at 0.5 MPa. The extruded hard-anodized aluminum barrel makes this unit shorter than a standard ISO 15552 cylinder of the same bore.
This configuration suits non-rotating or synchronized twin-tool duties perfectly. A useful computed insight for sizing is a safe working load of roughly 317 N, which translates to a vertical lift capacity of about 27 kg with a 2:1 safety margin. The unit uses a 1/4 inch port, includes adjustable 21 mm air cushions at both ends, and operates at 30-800 mm/s.

Where the Airtac SAUD Double Rod Cylinder SAUD40X115 Is Used
Twin-Tool Transfer
Drives two opposing grippers simultaneously with identical 528 N force, ensuring perfectly synchronized part handover between conveyor stations.
Anti-Rotation Lift
Lifts delicate electronics trays vertically without twisting, using the dual rods to maintain strict mechanical alignment throughout the 115 mm travel.
Dual-End Marking
Stamps or embosses serial numbers on both sides of a metal bracket in one motion, utilizing the equal push and pull dynamics of the piston.
Is the Airtac SAUD Double Rod Cylinder SAUD40X115 the Right Cylinder?
Choose this 40 mm bore if your application demands equal 528 N force in both directions, such as when driving twin tooling or needing mechanical anti-twist guidance. If you need less power, the 32 mm bore offers 345 N; for more power, 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. Since this 115 mm stroke is under 300 mm, side-load stress is minimal, but always guide the load externally for rigid setups. Note that this specific SKU lacks a magnet, so it cannot accept CMSG or DMSG sensors.
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 SAUD40X115 FAQ
The force is equal in both directions due to the double-rod design. It outputs 528 N at 0.5 MPa, 739 N at 0.7 MPa, and 950 N at 0.9 MPa. The 1/4 inch port supplies air to both chambers equally.
No, a plain cylinder drifts without live air, and the 21 mm cushions only decelerate near stroke end rather than locking the load. For vertical load holding, you must install an external rod lock or a pilot-operated check valve.
