The AirTAC Airtac SAUD Double Rod Cylinder SAUD100X400 is a genuine double-acting profile-type standard air cylinder with a Ø100mm bore and 400mm stroke, 1/2" 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.
The AirTAC SAUD100X400 is a double-acting, double-rod profile cylinder. A Ø25 mm rod exits both ends of the hard-anodized aluminum extruded barrel, meaning both faces use the rod-side area. Output is equal in both directions at 3681 N each way at 0.5 MPa. This profile body is noticeably shorter than an ISO 15552 cylinder of the same bore.
Because the piston travels a 400 mm distance, you should support external guides to prevent rod bending under side loads. The 1/2 inch port supplies ample flow for the 30-800 mm/s speed range. Without the -S magnet option, this specific SKU cannot accept CMSG or DMSG switches.

Double-rod model: the rod passes through the rear cover, so both piston faces lose rod area and push is shown at the annular-area value. Actual usable force is lower than theoretical due to friction and back-pressure. Size with a safety margin.

Drives two synchronized forming tools from one piston, ensuring perfectly matched contact pressure on both ends.
Uses the dual rods to prevent twist during high-speed package redirecting on a sorting line.
Applies equal downward and upward force to lower heavy platens smoothly without sagging.
When sizing this model, consider the neighboring bores. The 80 mm bore yields 2268 N both ways at 0.5 MPa, while the 100 mm bore provides 3681 N. Choose the double-rod configuration when your mechanism requires strict anti-rotation accuracy, needs to drive twin tooling simultaneously, or uses the back rod to trip a mechanical switch. Mounting is limited to Basic, FA flange, and LB foot styles, matching the AirTAC SC series. Because the 400 mm stroke creates leverage on the rod, always incorporate external linear guides to absorb side loads. Note that this non-magnetic version cannot host sensors.
Quick checklist
The force is equal in both directions due to the double-rod design. It outputs 3681 N at 0.5 MPa, 5153 N at 0.7 MPa, and 6626 N at 0.9 MPa. The 1/2 inch port feeds the 100 mm bore to maintain these figures across the 30-800 mm/s speed range.
No, a plain double-rod cylinder drifts without live air; the adjustable 29 mm cushions only decelerate near the stroke ends. For vertical load holding, install an external rod lock or a pilot-operated check valve.
