Airtac SAUD Double Rod Cylinder SAUD32X85
The AirTAC Airtac SAUD Double Rod Cylinder SAUD32X85 is a genuine double-acting profile-type standard air cylinder with a Ø32mm bore and 85mm 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 SAUD32X85
The AirTAC SAUD32X85 is a double-acting, double-rod profile cylinder. A 12 mm rod protrudes from both ends of the hard-anodized aluminum extrusion, meaning both faces use the rod-side area. Output is identical in extension and retraction, yielding 345 N each way at 0.5 MPa. The 1/8 inch port feeds this compact body, which is shorter than a standard ISO 15552 unit of the same bore.
This twin-rod architecture provides inherent anti-rotation guidance and lets you mount twin tooling or a switch cam on the back side. Because this specific SKU lacks the -S magnet, it cannot accept CMSG or DMSG sensors. Based on the 345 N 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. Note that the adjustable 21 mm cushions only decelerate the piston; they do not hold the load without live air.

Where the Airtac SAUD Double Rod Cylinder SAUD32X85 Is Used
Gripper Synchronization
Drives opposing gripper fingers with equal push and pull force, using the twin rods to prevent jaw twist during part clamping.
Twin Punch Tooling
Carries two small marking punches on opposite rod ends to stamp both sides of a thin metal tag in a single motion.
Compact Pressing
Applies a precise 345 N downward press force for seating small bearings, with the matching pull force ensuring clean retraction.
Is the Airtac SAUD Double Rod Cylinder SAUD32X85 the Right Cylinder?
Choose this 32 mm bore when you need 345 N of equal bidirectional force in a compact footprint. If your project requires less thrust, step down is not available as 32 mm is the smallest, but you can step up to the 40 mm bore for 528 N each way. The double-rod layout is the right call for synchronized lifting, anti-twist guidance, or driving two tools at once. Mounting is limited to Basic, FA flange, and LB foot styles, matching the AirTAC SC series. For the 85 mm stroke, side loads remain low, but always use external guide rails for any stroke exceeding 300 mm. Since this SKU has no -S magnet, you must select a magnet-equipped model if position sensing is required.
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 SAUD32X85 FAQ
Because it is a double-rod cylinder, the force is equal in both directions at 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 faces.
No, the cushions only decelerate motion near the stroke ends and do not lock the piston. To prevent drift on air loss, install an external rod lock or a pilot-operated check valve.
