Airtac SAUD Double Rod Cylinder SAUD32X220
The AirTAC Airtac SAUD Double Rod Cylinder SAUD32X220 is a genuine double-acting profile-type standard air cylinder with a Ø32mm bore and 220mm 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 SAUD32X220
The AirTAC SAUD32X220 is a double-acting, double-rod profile cylinder. A 12 mm rod exits both ends of the hard-anodized aluminum barrel, making the push and pull force equal at 345 N each way at 0.5 MPa. The extruded profile body is shorter than a standard ISO 15552 unit of the same bore. It uses a 1/8 inch port and adjustable 21 mm cushions.
This 32 mm bore unit yields a safe working load of about 207 N, or a vertical lift capacity near 18 kg with a 2:1 safety margin. The twin rods provide anti-rotation guidance and let you drive two tools at once. This SKU lacks a magnet, so it cannot carry a position sensor. For high heat up to 150 C, specify the Viton H seal option.

Where the Airtac SAUD Double Rod Cylinder SAUD32X220 Is Used
Twin-Tool Stamping
Drives two small marking pins simultaneously from opposite rod ends, ensuring perfectly synchronized indentations on thin metal strips.
Transfer Pusher
Pushes lightweight plastic trays across a belt with equal force in both directions, using the twin rods to prevent chassis twist during rapid reversals.
Gripper Actuator
Actuates a synchronized parallel gripper jaw set where equal opening and closing forces of 345 N are required for delicate component handling.
Is the Airtac SAUD Double Rod Cylinder SAUD32X220 the Right Cylinder?
Choose this 32 mm bore if you need 345 N of equal bidirectional force over a 220 mm stroke. Step down if your load is lighter, or step up to the 40 mm bore for 528 N each way at 0.5 MPa. A double rod is the right call for synchronized twin-tool duty or non-rotating anti-twist guidance. Mounting is limited to Basic, FA flange, and LB foot styles, matching the AirTAC SC series. At 220 mm stroke the side load is low, but always use external guide rails for heavy off-center masses. Remember this base model has no magnet, so order a -S variant if you need switch tracking.
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 SAUD32X220 FAQ
Because the 12 mm rod exits both ends, the 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. It uses a 1/8 inch port.
No. The adjustable 21 mm cushion only decelerates the piston near the stroke ends; it does not brake. For a held load, install an external rod lock or a pilot-operated check valve.
