About the Airtac SAID100 Double Rod Cylinder SAID100BX55S
The AirTAC SAID100X55-S is a double-acting, double-rod ISO 15552 profile cylinder featuring a 100mm bore and 55mm stroke. Because a rod exits both ends, the annulus area is identical on extend and retract, yielding an equal force of 3681 N each way at 0.5 MPa. It includes a magnet for position sensing.
Equipped with SUS304 stainless steel rods (option B), this model withstands corrosive environments. The rear rod extension allows you to mount a cam or position flag, while the twin-rod design inherently resists torsional load and keeps the workpiece guided against rotation.

Where the Airtac SAID100 Double Rod Cylinder SAID100BX55S Is Used
Symmetric Transfer
Drives a workpiece across two stations with identical push and pull force, ensuring consistent momentum and cycle timing in both directions.
Anti-Rotation Slides
The twin-rod geometry prevents torsional twist on heavy fixtures, maintaining precise alignment for machining or pressing operations.
Rear-Rod Sensing
Mounts a cam or DMSE sensor flag on the rear rod extension to trigger external sequencing without interfering with the primary work area.
Is the Airtac SAID100 Double Rod Cylinder SAID100BX55S the Right Cylinder?
Choose this 100mm bore when an application demands symmetric transfer force and dual-side guidance. If your mechanism requires less force, stepping down to the 80mm bore yields 2268 N both ways at 0.5 MPa. Conversely, moving up to 125mm provides 5734 N. The SAID design is selected over a single-rod SAI cylinder when anti-rotation stability or rear-rod sensing is required.
This cylinder uses a PT tapered G1/2 port and operates at 30-800 mm/s. It is dimensionally interchangeable per ISO 15552. Note that a plain SAID does not hold its load when air is exhausted; for fail-safe holding, consider the BSAID clamp-lock variant. The -S magnet works precisely with AirTAC CMSE reed and DMSE electronic sensors.

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 SAID100BX55S FAQ
Because it is a double-rod cylinder, the extend and retract forces are equal. It provides 3681 N both ways at 0.5 MPa, 5153 N at 0.7 MPa, and 6626 N at 0.9 MPa.
Yes. The SAID100X55-S is dimensionally interchangeable per ISO 15552 and uses the standard mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2), making it a drop-in replacement for other ISO 15552 double-rod cylinders.
