About the Airtac SAID32 Double Rod Cylinder SAID32AX850
The AirTAC SAID32X850 is a double-acting, double-rod ISO 15552 profile cylinder featuring a 32mm bore and 850mm stroke. Because the piston rod exits both end covers, the annulus area is identical on both sides, yielding perfectly symmetrical thrust. This design outputs 483N of force in both extend and retract directions at 0.7 MPa.
Equipped with SUS420J2 stainless steel rods (material code A), this variant offers enhanced corrosion resistance compared to standard carbon steel. The extruded aluminum barrel includes sensor grooves on both sides for flexible switch mounting. Note that because the rear rod protrudes during operation, you must allow extra clearance at the back of the cylinder.

Double-rod model: the rod passes through the rear cover, so both piston faces lose rod area and push is shown at the annular-area value. Actual usable force is lower than theoretical due to friction and back-pressure. Size with a safety margin.

Where the Airtac SAID32 Double Rod Cylinder SAID32AX850 Is Used
Anti-Rotation Slides
The twin-rod architecture prevents piston twisting, providing stable linear movement for precision sliding mechanisms without external guides.
Symmetric-Force Transfer
Delivers identical 483N force in both directions, ensuring consistent performance in push-pull transfer stations.
Dual-Side Actuation
Drive a primary workpiece on the front rod while using the rear rod extension to operate a secondary mechanism or mount a position flag.
Is the Airtac SAID32 Double Rod Cylinder SAID32AX850 the Right Cylinder?
Selecting this double-rod model over a single-rod SAI is primarily driven by the need for equal push and pull forces, plus dual-side guidance to prevent rotation. If your application requires less force, stepping down is not an option in this bore size, but stepping up to a 40mm bore provides 739N both ways at 0.7 MPa. At 850mm, this stroke is near the maximum standard limit for a 32mm bore, meaning the 12mm rod is highly susceptible to bending under side loads—an external guide rail is strongly recommended.
This cylinder uses a PT tapered port thread and operates at speeds of 30-800mm/s. It supports a reduced mounting set of Basic, FA, LB, TC, FTC, TCM1, and TCM2 (omitting FB, CA, CB, and CR). Remember that the adjustable air cushions only decelerate the piston near stroke end; they do not hold the load. If air pressure is lost, the cylinder will drift. For position holding without live pressure, consider an external rod lock or the BSAID clamp-lock variant.
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 SAID32 Double Rod Cylinder SAID32AX850 FAQ
Because it is a double-rod cylinder, the effective area is the same on both sides. It generates 345N at 0.5 MPa and 483N at 0.7 MPa in both the extend and retract directions.
Yes, the SAID32X850 is dimensionally interchangeable per ISO 15552 and can serve as a direct replacement for other ISO 15552 double-rod profile cylinders, provided you account for the rear rod protrusion.
