Airtac SAUD Double Rod Cylinder SAUD32X425S
The AirTAC Airtac SAUD Double Rod Cylinder SAUD32X425S is a genuine double-acting profile-type standard air cylinder with a Ø32mm bore and 425mm 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 SAUD32X425S
The AirTAC SAUD32X425S is a double-acting, double-rod profile cylinder. A 12mm rod exits both ends, meaning push and pull forces are identical at 345 N each way at 0.5 MPa. The extruded aluminum barrel is shorter than a standard ISO 15552 unit of the same 32mm bore. It features a 1/8 inch port and M10x1.25 rod threads.
This unit includes the -S magnet option for CMSG, DMSG or EMSG switches. The 425mm stroke requires external guide rails to prevent rod bending under side loads. Based on the 0.5 MPa 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. The air cushion only decelerates the piston; use an external rod lock to hold loads.

Where the Airtac SAUD Double Rod Cylinder SAUD32X425S Is Used
Synchronized Transfer
Drives two pick-and-place fingers simultaneously from one piston, keeping tooling perfectly aligned without twist.
Back-End Sensing Cam
Uses the protruding rear rod to trip a CMSG or DMSG switch, confirming full retraction in tight machinery spaces.
Balanced Vertical Lift
Lifts and lowers an 18 kg payload vertically with equal force both directions, preventing gravity-induced drift.
Is the Airtac SAUD Double Rod Cylinder SAUD32X425S the Right Cylinder?
Choose this 32mm bore delivering 345 N equal force if you need anti-rotation guidance or twin tooling. Stepping up to the 40mm bore yields 528 N both ways, while dropping to a smaller unit reduces thrust. This double-rod design allows a sensor cam on the back rod. Mounting uses SC-series compatible FA flange or LB foot brackets. Because the stroke is 425mm, always support the load with external guides to avoid rod bending.
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 SAUD32X425S FAQ
Because the 12mm rod exits both ends, force is equal in both directions: 345 N at 0.5 MPa, 483 N at 0.7 MPa, and 621 N at 0.9 MPa. The 1/8 inch port supplies air to both chambers.
No. The adjustable air cushions only decelerate the piston near the stroke ends. To prevent drift on air loss, you must install an external pilot-operated check valve or rod lock.
