Airtac SAUD Double Rod Cylinder SAUD32X25S
The AirTAC Airtac SAUD Double Rod Cylinder SAUD32X25S is a genuine double-acting profile-type standard air cylinder with a Ø32mm bore and 25mm 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 SAUD32X25S
The AirTAC SAUD32X25S is a double-acting, double-rod profile cylinder. A 12mm rod protrudes from both ends, meaning push and pull forces are identical at 345 N each way when operating at 0.5 MPa. The extruded aluminum barrel makes it shorter than an ISO 15552 unit of the same bore.
This 32mm bore unit features a 1/8" port and a 25mm stroke. The built-in magnet (-S) allows CMSG, DMSG, or EMSG switches to track position. With a 345 N output, your safe working load is roughly 207 N, translating to a vertical lift capacity of about 18 kg with a 2:1 safety margin. A Viton H seal option extends operation to 150 C.

Where the Airtac SAUD Double Rod Cylinder SAUD32X25S Is Used
Synchronized Transfer
Drives two opposing grippers simultaneously to pick and place delicate electronic components without rotational twist.
Twin Tooling Head
Powers a compact 32mm stamping or marking station where identical push and pull strokes are required for tool retraction.
Back-End Sensing
Utilizes the protruding rear rod to trip a CMSG reed switch, confirming full retraction in tight assembly machinery.
Is the Airtac SAUD Double Rod Cylinder SAUD32X25S the Right Cylinder?
Select the 32mm bore when you need 345 N of equal bidirectional force in a compact footprint. If your application requires less thrust, step down to a smaller bore; if you need more, step up to the 40mm bore which provides 528 N each way at 0.5 MPa. 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, and LB styles compatible with the AirTAC SC series. Because this 25mm stroke is short, side-load risks are minimal, but always guide external loads on longer strokes.
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 SAUD32X25S FAQ
Because this is a double-rod cylinder, the force is equal in both directions. It delivers 345 N at 0.5 MPa, 483 N at 0.7 MPa, and 621 N at 0.9 MPa. The unit operates at 30-800 mm/s and uses a 1/8" port.
No, a standard double-acting cylinder will drift if air is lost or the valve is centered. The adjustable 21mm air cushions only decelerate the piston near the stroke ends and do not act as a brake. Use an external rod lock or pilot-operated check valve for secure load holding.
