Airtac SAUD Double Rod Cylinder SAUD32X850
The AirTAC Airtac SAUD Double Rod Cylinder SAUD32X850 is a genuine double-acting profile-type standard air cylinder with a Ø32mm bore and 850mm 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 SAUD32X850
The AirTAC SAUD32X850 is a double-acting, double-rod profile cylinder featuring a 32 mm bore and an 850 mm stroke. A 12 mm rod exits both ends, meaning both faces use the rod-side piston area. This yields exactly 345 N of output force at 0.5 MPa in both directions. The extruded aluminum barrel keeps the unit shorter than an ISO 15552 cylinder of the same bore.
Because the rod protrudes at the back, you can mount a sensor cam or drive two tools simultaneously without rotation. This SKU lacks a magnet, so it cannot take a magnetic switch. Based on the 345 N figure, the safe working load is roughly 207 N, and it can vertically lift about 18 kg with a 2:1 margin. The 1/8" port and M10x1.25 rod thread match the bore specification.

Where the Airtac SAUD Double Rod Cylinder SAUD32X850 Is Used
Twin-Tool Transfer
Drives two synchronized grippers on a 850 mm transfer line, using the equal push and pull force to handle parts without rotational twist.
Guided Cutting Bed
Keeps a cutting blade perfectly aligned over a long 850 mm cut by using the dual rods for inherent anti-rotation stability.
Cam Trip Actuation
Uses the rear protruding rod to mechanically trip a limit switch at mid-stroke, ideal where electronic sensors are unsuitable.
Is the Airtac SAUD Double Rod Cylinder SAUD32X850 the Right Cylinder?
Choose this 32 mm bore when you need 345 N equal both ways at 0.5 MPa. If you need less force, the neighboring sizes do not go smaller in this series, but stepping up to the 40 mm bore provides 528 N. A double rod is the right call for anti-rotation guidance, twin tooling, or back-end cam trips. Mounting is limited to Basic, FA, and LB styles compatible with the AirTAC SC series. Since this is an 850 mm stroke, you must use external guides to prevent rod bending under side loads. This non-magnet SKU cannot accept sensors.
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 SAUD32X850 FAQ
The force is equal in both directions because the rod exits both ends. It provides 345 N at 0.5 MPa, 483 N at 0.7 MPa, and 621 N at 0.9 MPa. The 1/8" port supplies air to achieve these figures.
No, the air cushion only decelerates the piston near the stroke ends and does not act as a brake. If you need to hold a load on air loss, you must add an external rod lock or a pilot-operated check valve.
