About the Airtac SAID100 Double Rod Cylinder SAID100BX120S
The AirTAC SAID100X120-S is a double-acting, double-rod ISO 15552 profile cylinder featuring a 100mm bore and 120mm stroke. Because the twin rods occupy both sides of the piston, the annulus area is identical in each direction, yielding an equal extend and retract force of 3681N at 0.5MPa. A rod protrudes from both end covers, allowing you to mount the primary workpiece on one end and a secondary cam, position flag, or guide on the opposite end.
This specific configuration includes a SUS304 stainless steel rod for enhanced corrosion resistance and a built-in magnet (-S) for position sensing. The extruded aluminum barrel features sensor grooves on both sides, compatible with AirTAC CMSE reed and DMSE electronic solid-state switches. Fluid porting is via PT tapered threads sized at G1/2.

Where the Airtac SAID100 Double Rod Cylinder SAID100BX120S Is Used
Symmetric Force Transfer
Drives a shuttle mechanism where equal push and pull thrust of 3681N is critical, preventing directional bias in the motion control system.
Twin-Station Actuation
Mounts a machining tool on the front rod end and a synchronized ejector on the rear rod end to operate two separate stations in perfect phase.
Anti-Rotation Slides
Keeps heavy guided loads from twisting during transit by using the dual-rod geometry to resist torsional side-loads effectively.
Is the Airtac SAID100 Double Rod Cylinder SAID100BX120S the Right Cylinder?
Choose this 100mm bore when an application requires symmetric thrust and dual-side guidance that a single-rod SAI cannot provide. If your load demands less force, stepping down to an 80mm bore yields 2268N each way at 0.5MPa; if you need more thrust, a 125mm bore offers 5734N. This SAID100X120-S uses the reduced ISO 15552 mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2), deliberately omitting the FB, CA, CB, and CR accessories found on single-rod variants.
Remember that a plain double-rod cylinder does not hold its position if air pressure is lost or the valve is centered—the piston will drift. The adjustable air cushions at both ends only decelerate the piston near stroke end; they do not function as a lock. For true fail-safe holding without live pressure, consider an external pilot-operated check valve or the BSAID clamp-lock series.
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 SAID100BX120S FAQ
Because it is a double-rod cylinder, the effective piston area is identical on both sides, resulting in equal force in both directions. It delivers 3681N at 0.5MPa, 5153N at 0.7MPa, and 6626N at 0.9MPa for both extend and retract strokes.
Yes, the SAID100X120-S is dimensionally interchangeable per ISO 15552 mounting interface standards. It serves as a drop-in replacement for other ISO 15552 double-rod profile cylinders, provided you use the correct PT G1/2 ports and matching mounting accessories.
