Airtac SAUD Double Rod Cylinder SAUD32X115S
The AirTAC Airtac SAUD Double Rod Cylinder SAUD32X115S is a genuine double-acting profile-type standard air cylinder with a Ø32mm bore and 115mm stroke, 1/8" 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 SAUD32X115S
The AirTAC SAUD32X115S is a double-acting, double-rod profile cylinder featuring a 32 mm bore and 115 mm stroke. Because a rod exits both ends, the push and pull output is identical, delivering 345 N of force each way at 0.5 MPa. The extruded hard-anodized aluminum barrel makes it shorter than a standard ISO 15552 unit of the same bore.
This unit includes the -S magnet option for CMSG, DMSG, or EMSG switches. The 1/8" port and M10x1.25 rod thread keep the package compact. Based on the 345 N output, the safe working load is roughly 207 N, translating to a vertical lift capacity of about 18 kg with a 2:1 safety margin. For high-temperature environments up to 150 C, specify the Viton H seal.

Where the Airtac SAUD Double Rod Cylinder SAUD32X115S Is Used
Synchronized Transfer
Drives two parallel pick-and-place fingers simultaneously from one piston, ensuring perfectly synchronized part transfer without torsional twist.
Dual-End Sensing
Uses the protruding back rod to carry a switch cam, triggering an external sensor while the front rod performs the primary work.
Anti-Rotation Tooling
Prevents piston rotation during clamping or spotting tasks where angular stability is critical and space is restricted.
Is the Airtac SAUD Double Rod Cylinder SAUD32X115S the Right Cylinder?
Choose this 32 mm bore when you need 345 N of equal bidirectional force at 0.5 MPa. If your application requires less thrust, step down to a 32 mm unit; for heavier loads, step up to the 40 mm bore which provides 528 N each way. The double-rod architecture is ideal for anti-rotation guidance, driving twin tooling, or mounting a switch cam on the back rod. Mounting is limited to Basic, FA flange, and LB foot styles, matching the AirTAC SC series. The included -S magnet supports electronic position sensing. At 115 mm stroke, side loads are minimal, but external guides should always support the load to prevent binding.
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 SAUD32X115S FAQ
The force is equal in both directions because of the double-rod design. It outputs 345 N at 0.5 MPa, 483 N at 0.7 MPa, and 621 N at 0.9 MPa. The 1/8" port supplies air to both chambers.
No, a plain cylinder drifts without live air; the adjustable 21 mm cushions only decelerate near stroke end. To hold a load securely, install an external rod lock or a pilot-operated check valve.
