About the Airtac SAID32 Double Rod Cylinder SAID32AX185
The AirTAC SAID32X185 is a double-acting, double-rod ISO 15552 profile cylinder featuring a 32mm bore and 185mm stroke. Because a SUS420J2 stainless steel rod exits both end covers, the annulus area is identical on extend and retract, yielding an equal 483N of force each way at 0.7 MPa. It uses PT tapered port threads.
This through-rod design allows you to mount the primary workpiece on one end while using the opposite rear rod end for external guidance, a cam, or a position flag. The extruded aluminum barrel includes sensor grooves on both sides for flexible switch placement.
Choosing this twin-rod configuration over a single-rod SAI is primarily driven by anti-rotation needs and dual-side actuation. If your mechanism must hold its place without live air pressure, a plain SAID will drift; you should consider an external rod lock or the BSAID clamp-lock variant. For a direct replacement, match the 32mm bore, 185mm stroke, PT port, and mounting accessories from the SAID set: Basic, FA, LB, TC, FTC, TCM1, TCM2 (FB, CA, CB, and CR are omitted). Because the stroke is 185mm, side-load and rod-bearing bending are minimal, but long unsupported strokes still need an external guide.

Theoretical Output Force (Ø32mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 346 N | 346 N |
| 0.7 MPa | 484 N | — |
| Max (@1.0 MPa) | 70 kgf | |
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 SAID32AX185 Is Used
Anti-Rotation Slides
The twin-rod architecture prevents piston rotation, making it ideal for driving precision slides and lifting mechanisms that require strict linear guidance.
Symmetric-Force Transfer
Provides identical push and pull forces for transfer arms that must move loads with equal speed and power in both directions.
Through-Rod Sensing
The rear protruding rod can mount a cam or position flag to trigger external sensors without interfering with the primary workpiece on the front rod.
Is the Airtac SAID32 Double Rod Cylinder SAID32AX185 the Right Cylinder?
Select the 32mm bore when you need compact equal-force output; stepping down is not an option as this is the smallest standard size, while stepping up to a 40mm bore increases the both-way force to 528N at 0.5 MPa. The twin rods provide superior load guidance against rotation compared to a single-rod cylinder. Remember that the adjustable air cushions only decelerate the piston near stroke end and do not lock the load. This cylinder is dimensionally interchangeable per ISO 15552, serving as a direct replacement for other ISO 15552 double-rod cylinders.

- ✓ 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 SAID32AX185 FAQ
The double-rod design provides equal force in both directions: 345N at 0.5 MPa, 483N at 0.7 MPa, and 621N at 0.9 MPa.
Yes, the SAID32X185 is dimensionally interchangeable per ISO 15552 and serves as a direct replacement for other ISO 15552 double-rod cylinders, provided you match the 32mm bore, 185mm stroke, and PT port.
