Airtac SAID100 Double Rod Cylinder SAID100AX325
The AirTAC Airtac SAID100 Double Rod Cylinder SAID100AX325 is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø100mm bore and 325mm stroke, G1/2 air ports and adjustable end cushioning. Its standardized mounting interface makes it a drop-in replacement for other ISO 15552 cylinders in automation lines.

About the Airtac SAID100 Double Rod Cylinder SAID100AX325
The AirTAC SAID100X325 is a double-acting, double-rod ISO 15552 profile cylinder. A single piston drives a rod out of both end covers, yielding equal extend and retract forces. Because the annulus area is identical on both sides, this 100mm bore model generates 3681N each way at 0.5MPa, reaching 6626N at 0.9MPa.
This configuration features a SUS420J2 stainless steel rod and PT G1/2 tapered ports. The twin-rod layout allows mounting a primary workpiece on one end and a cam or position flag on the rear, providing dual-side guidance and superior anti-rotation resistance. The extruded aluminum barrel includes sensor grooves on both sides for adding CMSE reed or DMSE electronic switches.

Where the Airtac SAID100 Double Rod Cylinder SAID100AX325 Is Used
Symmetric Transfer
Drives a transfer carriage with equal push and pull force, maintaining consistent speed and thrust in both directions for smooth material handling.
Anti-Rotation Slides
The twin-rod architecture prevents mechanical twist during high-thrust machining operations, ensuring precise linear movement without rotational drift.
Rear-Flag Sensing
Mounts a primary tool on the front rod and a position flag on the rear rod, allowing external DMSE sensors to track stroke completion from the opposite side.
Is the Airtac SAID100 Double Rod Cylinder SAID100AX325 the Right Cylinder?
Choose this 100mm bore over the 80mm option (2268N at 0.5MPa) when your application requires higher symmetric thrust, or step down to the 125mm bore (5734N at 0.5MPa) if you need even greater force. The double-rod design is selected over a single-rod SAI when the mechanism demands twin-station actuation, rear-rod sensing, or strict load anti-rotation. For drop-in compatibility, it matches ISO 15552 mounting interface dimensions using PT G1/2 ports and accessories from the SAID set: Basic, FA, LB, TC, FTC, TCM1, and TCM2.
Since the 325mm stroke exceeds 300mm, the extended rod length increases the risk of side-load bending on the rod bearing; an external guide is recommended for heavy off-center loads. Note that a plain SAID does not hold its position when air is lost—the cushion only decelerates the piston near stroke end. For dead-load holding, consider an external pilot-operated check valve or the BSAID clamp-lock variant.
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 SAID100AX325 FAQ
Because the rod occupies both sides of the piston, the effective area is identical in both directions. The SAID100X325 generates 3681N both ways at 0.5MPa, 5153N at 0.7MPa, and 6626N at 0.9MPa.
Yes, it is dimensionally interchangeable per ISO 15552. It supports the SAID mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2) but omits FB, CA, CB, and CR mounts which are restricted to single-rod SAI cylinders.
