About the Airtac SAID100 Double Rod Cylinder SAID100X325
The AirTAC SAID100X325 is a double-acting, double-rod ISO 15552 profile cylinder featuring a 100mm bore and 325mm stroke. Because a piston rod extends from both end covers, the annulus area is identical on both sides, yielding equal force and speed in extend and retract. It provides 3681N of thrust each way at 0.5MPa and uses a 25mm carbon steel rod.
This through-rod architecture allows you to mount the primary workpiece on the front rod end while using the rear protrusion for a position flag, cam, or secondary mechanism. The extruded aluminum barrel includes sensor grooves on both sides, and if a magnet is added, it supports AirTAC CMSE reed and DMSE electronic solid-state switches.

Where the Airtac SAID100 Double Rod Cylinder SAID100X325 Is Used
Symmetric Force Transfer
Drives a shuttle mechanism where the 3681N push and pull forces must be perfectly matched to move heavy jigs equally in both directions without speed variations.
Anti-Rotation Slides
The twin-rod geometry keeps the load guided and prevents torsional twisting on precision machining slides where a single rod would allow unwanted rotational play.
Dual-Station Actuation
Mounts a primary tool on the front rod end and a secondary cam or limit flag on the rear protrusion to trigger sequence valves or sensors in a secondary station.
Is the Airtac SAID100 Double Rod Cylinder SAID100X325 the Right Cylinder?
Select this 100mm bore when an application requires symmetric thrust around 3681N at 0.5MPa in both directions, or step down to the 80mm bore (2268N) if your load is lighter. A double-rod design is chosen over a single-rod SAI when you need dual-side guidance to prevent rotation or require actuation at both ends. To match this cylinder for an ISO 15552 drop-in replacement, verify the 325mm stroke, G1/2 port, PT thread, and mounting accessory.
At 325mm of stroke, the unsupported rod length increases the risk of bending under side loads. Use an external guide rail to support the payload and protect the internal rod bearing. Note that the adjustable air cushions at both ends only decelerate the piston near stroke end; they do not hold the load if air pressure is lost. For position holding without live pressure, consider a BSAID clamp-lock cylinder or an external pilot-operated check valve.
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 SAID100 Double Rod Cylinder SAID100X325 FAQ
Because it is a double-rod cylinder, the effective piston area is the same on both sides. It delivers 3681N of force in both extend and retract directions at 0.5MPa, and 5153N at 0.7MPa.
Yes, the SAID100X325 is dimensionally interchangeable per ISO 15552. You can drop it in for other standard profile cylinders with a 100mm bore and 325mm stroke, using the Basic, FA, LB, TC, FTC, TCM1, or TCM2 mounting interfaces.
