About the Airtac SAID100 Double Rod Cylinder SAID100BX275S
The AirTAC SAID100X275-S is a double-acting, double-rod ISO 15552 profile cylinder featuring a 100mm bore and 275mm stroke. A single piston drives a SUS304 stainless steel rod out of both end covers. Because the rod occupies both sides of the piston, the effective annulus area is identical in each direction, yielding an equal extend and retract force of 3681N at 0.5MPa (up to 6626N at 0.9MPa). Equipped with a magnet, it works seamlessly with AirTAC CMSE reed and DMSE solid-state sensors.
This design allows you to mount a workpiece on one rod end and a position flag, cam, or secondary tool on the opposite end. The twin-rod architecture provides superior dual-side guidance and resists torsional rotation better than a single-rod SAI cylinder. The extruded aluminum barrel includes sensor grooves on both sides, and the unit uses PT tapered port threads (G1/2) for reliable pneumatic sealing.

Where the Airtac SAID100 Double Rod Cylinder SAID100BX275S Is Used
Symmetric Transfer
Drives a transfer carriage with equal push and pull force, ensuring consistent acceleration and deceleration cycles without asymmetric speed drift.
Anti-Rotation Slides
Twin rods prevent the load from twisting during vertical or horizontal transit, maintaining strict alignment for precision tooling.
Dual-Station Actuation
Mounts the primary workpiece on the front rod and a secondary mechanism or position flag on the rear rod to sequence two operations from one cylinder.
Is the Airtac SAID100 Double Rod Cylinder SAID100BX275S the Right Cylinder?
Choose this 100mm bore double-rod cylinder when symmetric force and anti-rotation guidance are critical. It delivers 3681N both ways at 0.5MPa; if your application requires less force, step down to the 80mm bore (2268N both ways), or if you need more, move up to the 125mm bore (5734N both ways). The double rod is specifically selected over a single-rod SAI when you need to drive twin stations, mount rear-side sensors, or prevent the load from twisting during transit.
Because the stroke is 275mm, the unsupported rod length during extension is significant. To prevent rod-bearing bending under side loads, use an external guide rail to support the payload. Note that this plain double-rod cylinder does not hold its position when air pressure is lost; the piston will drift if the valve is centered or pressure is exhausted. For position holding without live pressure, consider an external pilot-operated check valve or a BSAID clamp-lock cylinder. This model is dimensionally interchangeable per ISO 15552, offering a drop-in replacement for other ISO 15552 double-rod cylinders using the Basic, FA, LB, TC, FTC, TCM1, or TCM2 mounting set.

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 SAID100BX275S FAQ
Because it is a double-rod cylinder, the push and pull forces are equal. It generates 3681N at 0.5MPa, 5153N at 0.7MPa, and 6626N at 0.9MPa in both directions.
Yes, the SAID100X275-S is dimensionally interchangeable per ISO 15552. It serves as a drop-in replacement for other ISO 15552 profile double-rod cylinders, using the standard Basic, FA, LB, TC, FTC, TCM1, and TCM2 mounting accessories.
