About the Airtac SAID100 Double Rod Cylinder SAID100BX425S
The AirTAC SAID100X425-S is a double-acting, double-rod ISO 15552 profile cylinder featuring a 100mm bore and 425mm stroke. Because a stainless steel SUS304 rod exits both ends, the annulus area is identical on extend and retract, yielding an equal 3681N of force each way at 0.5 MPa. The -S suffix indicates an integrated magnet for position sensing.
This design lets you mount the primary workpiece on one rod end and a cam, guide, or position flag on the opposite rear rod. The extruded aluminum barrel includes sensor grooves on both sides for CMSE reed or DMSE solid-state switches, while adjustable air cushions at both ends absorb kinetic energy near stroke extremes.

Where the Airtac SAID100 Double Rod Cylinder SAID100BX425S Is Used
Symmetric Force Transfer
Drives horizontal transfer arms where the 3681N push and pull forces must be perfectly matched to avoid jerky movements during rapid direction changes.
Anti-Rotation Slides
Uses the dual SUS304 rods to guide lifting slides and prevent platform twist, keeping the tool plate perfectly parallel without external guides.
Rear-End Sensing
Mounts a physical cam on the rear rod end to trigger external proximity sensors, reserving the front rod entirely for the primary workpiece.
Is the Airtac SAID100 Double Rod Cylinder SAID100BX425S the Right Cylinder?
Choose this 100mm bore over the 80mm option (2268N at 0.5 MPa) when your mechanism requires higher symmetric thrust, or step down to a 63mm bore (1402N) if payload is lighter. The twin rods provide superior anti-rotation resistance and allow dual-side actuation compared to a single-rod SAI, though a plain SAID will drift if air pressure is lost—use a BSAID clamp-lock or external pilot-operated check valve if the load must be held.
At 425mm of travel, the unsupported stroke length increases rod-bearing bending moments under side loads; adding an external linear guide is recommended. This cylinder is dimensionally interchangeable per ISO 15552, uses a PT G1/2 port, and supports Basic, FA, LB, TC, FTC, TCM1, and TCM2 mountings (omitting FB, CA, CB, and CR).

- ✓ 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 SAID100BX425S FAQ
It provides 3681N of force at 0.5 MPa, 5153N at 0.7 MPa, and 6626N at 0.9 MPa. Because it is a double-rod cylinder, this pull-side force figure is identical for both extension and retraction.
The twin rods exit both ends to allow dual-side guidance, rear-rod cam mounting, and equal speed both ways. It is a drop-in replacement for other ISO 15552 profile cylinders, using a reduced mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2) without FB or CA options.
