Airtac SAUD Double Rod Cylinder SAUD32X140
The AirTAC Airtac SAUD Double Rod Cylinder SAUD32X140 is a genuine double-acting profile-type standard air cylinder with a Ø32mm bore and 140mm 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 SAUD32X140
The AirTAC SAUD32X140 is a double-acting, double-rod profile cylinder. A 12mm rod exits both ends of the hard-anodized aluminum extrusion, meaning both faces use the rod-side piston area. This yields equal push and pull force of 345 N each way at 0.5 MPa. The unit carries a 1/8 inch port and M10x1.25 rod threads.
Because the extruded profile omits external rods, it is noticeably shorter than an ISO 15552 unit of the same bore. The twin rods provide inherent anti-twist guidance for non-rotating loads. For sizing, the safe working load is roughly 207 N, and it can vertically lift about 18 kg with a 2:1 safety margin. This SKU lacks a magnet, so it cannot accept CMSG or DMSG sensors.

Where the Airtac SAUD Double Rod Cylinder SAUD32X140 Is Used
Synchronized Transfer
Drives two parallel pick-and-place fingers simultaneously from one piston, keeping tooling perfectly aligned without twisting.
Profile Cutting Stop
Uses the twin rods to present a rigid, non-rotating backstop for short material lengths in a compact packaging cell.
Dual-End Ejector
Pushes a part forward while the rear rod simultaneously trips a mechanical valve to confirm ejection stroke completion.
Is the Airtac SAUD Double Rod Cylinder SAUD32X140 the Right Cylinder?
Choose this 32mm bore when you need perfectly matched push and pull forces. If you need more power, the 40mm bore offers 528 N both ways at 0.5 MPa; if less is required, there is no smaller standard SAUD size. The double-rod layout is ideal for anti-rotation, twin-tool driving, or mounting a switch cam on the back rod. Mounting is limited to Basic, FA flange, and LB foot brackets, matching the AirTAC SC series. At 140mm stroke, side loads are minimal, but always use external guides for longer 300mm plus strokes. Note this non-magnetic SKU cannot host position sensors.

- ✓ 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 SAUD32X140 FAQ
The force is equal in both directions because both faces have a rod. It generates 345 N at 0.5 MPa, 483 N at 0.7 MPa, and 621 N at 0.9 MPa. The 1/8 inch port feeds both chambers equally.
No. A plain double-rod cylinder drifts without live air, as the adjustable cushions only decelerate near stroke ends. For suspended loads, install an external rod lock or pilot-operated check valve.
