About the Airtac SAID32 Double Rod Cylinder SAID32X40S
The AirTAC SAID32X40-S is a double-acting, double-rod ISO 15552 profile cylinder equipped with a magnet for position sensing. Because a carbon steel rod exits both end covers, the annulus area is identical on extend and retract. This means it delivers exactly 345 N of force in both directions at 0.5 MPa, ensuring perfectly symmetric speed and thrust for balanced motion tasks.
Beyond equal force, the through-rod design allows you to mount the primary workpiece on one end while attaching a cam, external guide, or a position flag on the rear rod end. The extruded aluminum barrel features sensor grooves on both sides compatible with CMSE reed and DMSE electronic switches. It utilizes a PT tapered port thread and includes adjustable air cushions at both ends to decelerate the piston near stroke limits.

Theoretical Output Force (Ø32mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 346 N | 346 N |
| 0.7 MPa | 484 N | — |
| Max (@1.0 MPa) | 70 kgf | |
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 SAID32X40S Is Used
Symmetric Force Transfer
Drives a transfer mechanism where equal push and pull thrust (345 N both ways) prevents asymmetric acceleration, ensuring smooth part handoff between stations.
Anti-Rotation Slides
Uses the twin-rod geometry to guide a clamping slide against rotational torque, keeping the tool plane perfectly parallel to the workpiece.
Through-Rod Sensing
Actuates a primary gripper on the front stroke while the rear rod end drives a cam flag past a DMSE electronic sensor to confirm full extend position.
Is the Airtac SAID32 Double Rod Cylinder SAID32X40S the Right Cylinder?
Select this 32mm bore when an application demands anti-rotation guidance or dual-side actuation that a single-rod SAI cannot provide. If your mechanism requires slightly less force, stepping down is not an option below 32mm in this series, but stepping up to a 40mm bore yields 528 N both ways at 0.5 MPa. Choose the SAID32X40-S specifically for short-stroke, twin-station operations where rear-rod clearance is tight but rear-side sensing is required.
As an ISO 15552 profile cylinder, it is dimensionally interchangeable with other ISO 15552 double-rod cylinders, allowing a direct upgrade without altering machine footprint. The -S suffix indicates the integrated magnet for CMSE/DMSE switches. Note that the adjustable cushions only decelerate the piston; they do not hold a load. If position holding without air pressure is required, consider an external rod lock or the SAIL/BSAID series. Mounting options include Basic, FA, LB, TC, FTC, TCM1, and TCM2.
Quick checklist
- ✓ Required force at your working pressure
- ✓ Stroke and mounting space
- ✓ Port/thread type (PT/NPT/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/TC).
- check Installation by qualified personnel per AirTAC docs.
Airtac SAID32 Double Rod Cylinder SAID32X40S FAQ
Because the rod occupies both sides of the piston, the effective area is the same in both directions. It provides 345 N of force both extending and retracting at 0.5 MPa, and 621 N both ways at 0.9 MPa.
Yes, it shares the exact ISO 15552 mounting interface and can be a direct replacement for other ISO 15552 double-rod cylinders. However, ensure you have adequate rear clearance for the protruding secondary rod.
