Airtac SAUD Double Rod Cylinder SAUD32X185
The AirTAC Airtac SAUD Double Rod Cylinder SAUD32X185 is a genuine double-acting profile-type standard air cylinder with a Ø32mm bore and 185mm 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 SAUD32X185
The AirTAC SAUD32X185 is a double-acting, double-rod profile cylinder. A 12mm rod exits both ends of the hard-anodized extruded aluminum barrel, meaning both faces use the rod-side piston area. This yields exactly 345 N of thrust and pull at 0.5 MPa. The unit is notably shorter than a standard ISO 15552 cylinder of the same bore, and mounts via FA flange or LB foot brackets compatible with the AirTAC SC series.
Because the piston rod protrudes at the rear, the cylinder provides inherent anti-rotation guidance and can drive twin tooling simultaneously. From the 345 N baseline, your safe working load is roughly 207 N, translating to a vertical lift capacity of about 18 kg with a 2:1 safety margin. This specific SKU lacks a magnet, so it cannot accept CMSG or DMSG sensors. Note that the 1/8" port feeds the chamber, and the 21mm adjustable air cushions only decelerate the piston near stroke end.

Where the Airtac SAUD Double Rod Cylinder SAUD32X185 Is Used
Twin-Tool Transfer
Drives two opposing pick-off fingers simultaneously with equal 345 N force, ensuring perfectly synchronized part ejection without twisting.
Anti-Rotation Stopper
Uses the dual-rod geometry to resist torsional deflection, acting as a rigid guide pin for a 185mm stroke length on a clamping fixture.
Mechanical Cam Trip
Leverages the rear protruding rod to physically strike an external mechanical limit switch, providing a hard positional confirmation without onboard sensors.
Is the Airtac SAUD Double Rod Cylinder SAUD32X185 the Right Cylinder?
Choose this 32mm bore when you need 345 N of equal bidirectional force at 0.5 MPa. If your project requires less push, stepping down is not an option as 32mm is the smallest available SAUD size. If you need more power, the 40mm bore provides 528 N each way. The 185mm stroke is well within the 1000mm standard limit, but at this length you should ensure external linear guides support any side loads to prevent binding. Select this double-rod architecture specifically for non-rotating duties, synchronized twin-tool setups, or when a back rod is needed to trip a mechanical switch. Remember this non-magnetic variant cannot host sensors, and a plain cylinder drifts on air loss, so add an external rod lock for vertical holding.
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 SAUD32X185 FAQ
The force is equal in both directions because the 12mm rod exits both ends. It generates 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 achieve these figures.
No, the 21mm adjustable cushions only decelerate the piston near the stroke ends; they do not lock the load. On air loss, the rod will drift. You must install an external pilot-operated check valve or rod lock to hold a suspended load.
