About the Airtac SAID32 Double Rod Cylinder SAID32X425S
The AirTAC SAID32X425-S is a double-acting, double-rod ISO 15552 profile cylinder. A single piston drives a carbon steel rod out of both end covers, yielding equal extend and retract forces. It generates 345N of thrust in each direction at 0.5MPa, scaling to 621N at 0.9MPa. Because the annulus area is identical on both faces, push and pull forces match perfectly.
This variant includes a magnetic piston (-S) for position sensing via CMSE reed or DMSE electronic switches housed in the dual side sensor grooves. The rear rod extension is ideal for mounting a cam or position flag, while the PT G1/8 port and M10x1.25 rod thread keep the 32mm bore compact for multi-station actuation.

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 SAID32X425S Is Used
Symmetric Force Transfer
Drives a transfer carriage with identical 345N push and pull forces at 0.5MPa, ensuring consistent acceleration and deceleration cycles without pressure compensation.
Dual-Side Tooling Actuation
Mounts the primary workpiece on the front rod and a secondary cam or position flag on the rear rod to trigger external reed sensors at mid-stroke.
Anti-Rotation Slides
The twin-rod geometry prevents piston rotation during vertical lifting tasks, keeping guided slides perfectly aligned without external linear bearings.
Is the Airtac SAID32 Double Rod Cylinder SAID32X425S the Right Cylinder?
Choose this 32mm bore when an application requires equal 345N force both ways at 0.5MPa, stepping down from a 40mm bore (528N) if symmetric thrust is more critical than raw power. A double-rod design is selected over a single-rod SAI when the mechanism needs dual-side guidance, anti-rotation stability, or rear-rod sensing. For direct replacements, match the 425mm stroke, PT G1/8 port, and the SAID mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2), noting that FB, CA, CB, and CR brackets are omitted.
At 425mm stroke, the unsupported rod length increases bending moments and side-load risk on the rod bearing; an external guide rail is recommended to prevent premature wear. Note that the adjustable air cushions at both ends only decelerate the piston near stroke end and do not hold the load if air pressure is lost—use a SAIL lock or external check valve for position holding.
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 SAID32X425S FAQ
Because the rod exits both sides, the effective piston area is identical in both directions. It delivers 345N at 0.5MPa, 483N at 0.7MPa, and 621N at 0.9MPa on both extend and retract strokes.
Yes, it is dimensionally interchangeable per ISO 15552 profile standards. You can drop it in as a replacement for other 32mm bore double-rod cylinders by matching the 425mm stroke, PT G1/8 port, and standard mounting interface.
