Airtac SAUD Double Rod Cylinder SAUD32X145S
The AirTAC Airtac SAUD Double Rod Cylinder SAUD32X145S is a genuine double-acting profile-type standard air cylinder with a Ø32mm bore and 145mm 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 SAUD32X145S
The AirTAC SAUD32X145S is a double-acting, double-rod profile cylinder. A 12mm rod exits both ends of the hard-anodized aluminum barrel, meaning both faces use the rod-side area. This yields exactly 345 N of thrust and retraction force at 0.5 MPa. The extruded profile body is noticeably shorter than a standard ISO 15552 unit of the same 32mm bore. It features a 1/8 inch port and M10x1.25 rod threads.
Because the -S suffix denotes a built-in piston magnet, this model supports CMSG, DMSG, and EMSG switches for end-of-stroke detection. The twin rods provide inherent anti-rotation guidance and let you mount a sensor cam on the back rod. For sizing, the safe working load is roughly 207 N, and it can vertically lift about 18 kg with a 2:1 safety margin. The standard 21mm adjustable air cushions at both ends absorb kinetic energy near stroke end.

Where the Airtac SAUD Double Rod Cylinder SAUD32X145S Is Used
Twin-Tool Stamping
Drives two small marking pins simultaneously from opposite ends, ensuring perfectly synchronized indentation on thin metal strips.
Transfer Pusher
Pushes lightweight cartons on a belt while the rear rod trips an external mechanical limit switch to confirm cycle completion.
Gripper Actuator
Powers a small pneumatic gripper where equal clamping and release forces are required to prevent distorting delicate plastic parts.
Is the Airtac SAUD Double Rod Cylinder SAUD32X145S the Right Cylinder?
Choose this 32mm bore when you need identical push and pull power in a compact envelope. If you need more force, the 40mm bore delivers 528 N both ways at 0.5 MPa; if you need less, AirTAC does not offer a smaller SAUD size, so the 32mm is the minimum. The twin rods are ideal for non-rotating loads, driving two tools at once, or carrying a switch cam on the rear extension. Mounting is limited to Basic, FA flange, and LB foot styles, matching the AirTAC SC series. At 145mm stroke, side loads are minimal, but always guide external rods to prevent binding. The -S magnet allows CMSG, DMSG, and EMSG sensors. For temperatures up to 150 C, specify the Viton H seal option.
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 SAUD32X145S FAQ
Because it is a double-rod cylinder, the force is equal in both directions. It generates 345 N at 0.5 MPa, 483 N at 0.7 MPa, and 621 N at 0.9 MPa. We never quote a larger single-rod push value because both faces lose area to the 12mm rod.
No, a plain double-rod cylinder will drift if air pressure drops or the valve is centered. The 21mm adjustable air cushions only decelerate the piston near the stroke ends; they do not lock the load. Use an external rod lock or pilot-operated check valve for holding.
