Airtac SAUD Double Rod Cylinder SAUD32X400
The AirTAC Airtac SAUD Double Rod Cylinder SAUD32X400 is a genuine double-acting profile-type standard air cylinder with a Ø32mm bore and 400mm 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 SAUD32X400
The AirTAC SAUD32X400 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 equal force both ways, delivering 345 N at 0.5 MPa. The extruded profile body is notably shorter than an ISO 15552 cylinder of the same bore.
Because this SKU lacks the -S magnet, it cannot take a magnetic switch. The 1/8" port and M10x1.25 rod thread are fixed by the 32mm bore. For sizing, a safe working load is roughly 207 N (about 60% of the 0.5 MPa figure), equating to a vertical lift of 18 kg with a 2:1 margin.

Where the Airtac SAUD Double Rod Cylinder SAUD32X400 Is Used
Synchronized Gripper Jaws
Drives opposing gripper fingers with identical push and pull force, ensuring parts are centered without twist during handling.
Twin-Tool Punching
Mounts a punch on the front rod and an ejector on the back, striking both sides of a workpiece in one compact motion.
Non-Rotating Lift Stage
The dual rods prevent mechanical rotation during vertical lifts, keeping precision tooling perfectly aligned over 400mm.
Is the Airtac SAUD Double Rod Cylinder SAUD32X400 the Right Cylinder?
When sizing this 32mm bore, step down or up using the equal-both-ways 0.5 MPa figures: a 40mm bore gives 528 N, while a smaller option is unavailable in this series. A double rod is the right call for anti-rotation guidance, driving twin tooling, or carrying a switch cam on the back rod. Mounting is limited to Basic, FA, and LB types, matching the AirTAC SC series. At 400mm stroke, external guides are recommended to prevent rod bending under side loads. Note this non-magnet SKU cannot host 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 SAUD32X400 FAQ
The force is equal both ways because rods exit 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 feeds both chambers identically.
No. The air cushions only decelerate the piston near stroke end; they do not lock. On air loss, the piston drifts. Use an external rod lock or pilot-operated check valve for load holding.
