About the Airtac SAID80 Double Rod Cylinder SAID80BX185S
The AirTAC SAID80X185-S is a double-acting, double-rod ISO 15552 profile cylinder featuring a 185mm stroke and an integrated magnet. Because the piston rod extends from both end covers, the effective annulus area is identical on both sides, yielding exactly 2268N of thrust and retraction force at 0.5MPa. This symmetric output is ideal for mechanisms requiring consistent dynamic performance in both travel directions.
Equipped with a SUS304 stainless steel rod, this variant provides superior corrosion resistance for harsh environments. The -S magnet enables position sensing via CMSE reed or DMSE electronic switches fitted into the dual sensor grooves machined into the extruded aluminum barrel. A rear rod protrusion allows engineers to mount a secondary cam or limit flag opposite the primary workpiece.

Where the Airtac SAID80 Double Rod Cylinder SAID80BX185S Is Used
Symmetric Force Transfer
Drives transfer shuttles where the 2268N equal force in both directions ensures smooth, balanced acceleration and deceleration of heavy pallets.
Anti-Rotation Guidance
The dual-rod design resists torsional twisting on precision slides, keeping the workpiece perfectly aligned without needing external guide rails.
Rear-End Sensing
Mounts a secondary cam or flag on the rear rod extension to trigger DMSE electronic sensors for a secondary confirmation signal independent of the main tool.
Is the Airtac SAID80 Double Rod Cylinder SAID80BX185S the Right Cylinder?
Select this 80mm bore when an application demands identical push and pull forces, stepping up from the 63mm bore (1402N at 0.5MPa) or down from the 100mm bore (3681N at 0.5MPa). The twin-rod architecture provides inherent anti-rotation guidance compared to a single-rod SAI, supporting dual-side loads or rear-mounted position flags. Note that the adjustable air cushions only decelerate the piston near stroke end; they do not lock the load. If pressure is lost, use an external rod lock or a BSAID clamp-lock cylinder to hold position.
As a dimensionally interchangeable ISO 15552 component, it drops in seamlessly with other standard profile cylinders. It uses PT tapered ports (G3/8) and supports a reduced mounting set including Basic, FA, LB, TC, FTC, TCM1, and TCM2 (omitting FB, CA, CB, and CR). The 185mm stroke falls below the 1500mm maximum standard, requiring no special made-to-order handling.
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 SAID80 Double Rod Cylinder SAID80BX185S FAQ
Because the rod occupies both sides of the piston, the push and pull forces are equal. It generates 2268N in both directions at 0.5MPa, 3175N at 0.7MPa, and 4082N at 0.9MPa.
Yes, it is dimensionally interchangeable per ISO 15552 profile standards. It uses standard mounting accessories like FA, LB, and TC brackets, though it omits FB, CA, CB, and CR mounts.
