About the Airtac SAID32 Double Rod Cylinder SAID32X240S
The AirTAC SAID32X240-S is a double-acting, double-rod ISO 15552 profile cylinder. A single piston pushes a carbon steel rod out of both end covers, yielding identical extend and retract forces. Because the annulus area is symmetrical, you get 483 N of thrust and 483 N of pull force at 0.5 MPa, moving at 30-800 mm/s across its 240 mm stroke.
This through-rod layout lets you mount the primary workpiece on the front end and a cam, position flag, or secondary mechanism on the rear. The integrated -S magnet triggers AirTAC CMSE reed and DMSE solid-state sensors housed in the dual-side barrel grooves. Adjustable air cushions at both ends absorb end-of-stroke impact, though they do not lock the load if air pressure drops.

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.

Where the Airtac SAID32 Double Rod Cylinder SAID32X240S Is Used
Symmetric Force Transfer
Drives a shuttle mechanism where the equal annulus area ensures the 483 N push and pull forces remain perfectly matched, stabilizing cycle timing.
Anti-Rotation Slides
Uses the twin-rod geometry to guide a vertical lifting slide, preventing piston rotation without requiring external guide rails.
Through-Rod Sensing
Actuates the primary tool on the front stroke while the rear rod end drives a cam past a DMSE solid-state sensor for end-position confirmation.
Is the Airtac SAID32 Double Rod Cylinder SAID32X240S the Right Cylinder?
Select this 32 mm bore when an application demands equal push and pull velocity, or needs rear-rod actuation for a second station. If your mechanism requires higher thrust, stepping up to the 40 mm bore raises the bidirectional force to 528 N at 0.5 MPa. Conversely, if you only need one-way actuation, the standard single-rod SAI provides a larger extend force. For holding a load during an air-loss event, choose a SAIL lock or BSAID clamp-lock variant instead of relying on the cushion.
As a dimensionally interchangeable ISO 15552 cylinder, it drops into existing 32 mm bore footprints using the Basic, FA, LB, TC, FTC, TCM1, or TCM2 mounting styles (the FB, CA, CB, and CR variants are reserved for single-rod units). The G1/8 PT port and M10x1.25 rod thread set the flow and connection limits. At 240 mm stroke, the unsupported rod length is moderate, but for heavier radial loads, an external guide is recommended to prevent rod-bearing bending.

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/TC).
- check Installation by qualified personnel per AirTAC docs.
Airtac SAID32 Double Rod Cylinder SAID32X240S FAQ
Because the double-rod design subtracts the rod area from both sides of the piston, the extend and retract forces are equal. It generates 345 N at 0.5 MPa, 483 N at 0.7 MPa, and 621 N at 0.9 MPa in both directions.
Yes, the SAID32X240-S is a profile cylinder with an ISO 15552 mounting interface, making it dimensionally interchangeable with other ISO 15552 double-rod cylinders of the same bore size. It uses a G1/8 PT port and M10x1.25 rod thread.
