About the Airtac SAID100 Double Rod Cylinder SAID100BX185S
The AirTAC SAID100X185-S is a double-acting, double-rod ISO 15552 profile cylinder featuring a 100mm bore and 185mm stroke. Because the twin SUS304 stainless steel rods occupy both sides of the piston, the effective annulus area is identical in each direction, yielding an equal extend and retract force of 3681 N at 0.5 MPa.
A rod protrudes from both end covers, allowing you to mount the primary workpiece on the front and a position flag or cam on the rear. The extruded aluminum barrel includes sensor grooves on both sides, and the integrated magnet (-S) directly supports AirTAC CMSE reed and DMSE electronic solid-state switches.

Where the Airtac SAID100 Double Rod Cylinder SAID100BX185S Is Used
Symmetric Force Transfer
Drives a secondary mechanism from the rear rod end while delivering an identical 3681 N push and pull force on the front end, ensuring perfectly balanced dual-station actuation.
Anti-Rotation Slides
The twin SUS304 rods provide high torsional rigidity, preventing piston rotation and maintaining precise alignment for heavy lifting or pressing slides.
Through-Rod Sensing
Utilizes the rear rod extension to mount a physical cam or limit flag, while the internal magnet interfaces with DMSE electronic sensors for redundant position verification.
Is the Airtac SAID100 Double Rod Cylinder SAID100BX185S the Right Cylinder?
Select this 100mm bore when an application demands symmetric thrust and dual-side actuation that a single-rod SAI cannot provide. If your payload is lighter, stepping down to the 80mm bore offers 2268 N both ways at 0.5 MPa; if you need heavier symmetric drive, the 125mm bore provides 5734 N. This cylinder uses PT tapered ports and accepts the standard ISO 15552 mounting set: Basic, FA, LB, TC, FTC, TCM1, and TCM2.
Note that a plain SAID does not hold its position if air pressure is lost or the valve is centered, as the adjustable air cushions only decelerate the piston near stroke end and do not act as a mechanical lock. For any stroke of 185mm, the 25mm rod diameter handles moderate side loads well, but external guidance is recommended for heavy off-center loads.
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 SAID100BX185S FAQ
Because it is a double-rod cylinder, the push and pull forces are equal. It generates 3681 N in both directions at 0.5 MPa, 5153 N at 0.7 MPa, and 6626 N at 0.9 MPa.
Yes, it is dimensionally interchangeable per ISO 15552 and serves as a drop-in replacement for other ISO 15552 profile double-rod cylinders, utilizing the standard Basic, FA, LB, and TC mounting interfaces.
