About the Airtac SAID32 Double Rod Cylinder SAID32AX155S
The AirTAC SAID32X155-S is a double-acting, double-rod ISO 15552 profile cylinder featuring a 32mm bore and 155mm stroke. Because the piston rod exits both end covers, the effective annulus area is identical on extend and retract, yielding equal push and pull forces of 483N at 0.7 MPa. The rear rod end is ideal for mounting a cam, position flag, or secondary mechanism while keeping the load guided against rotation.
This non-standard stroke unit is equipped with a SUS420J2 stainless steel rod (option A) for enhanced corrosion resistance and utilizes PT tapered port threads. The included -S magnet operates seamlessly with AirTAC CMSE reed and DMSE solid-state sensors via the dual-side barrel grooves, while adjustable air cushions at both ends decelerate the piston near stroke end.

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 SAID32AX155S Is Used
Symmetric Force Transfer
Drives a workpiece on one end and a synchronized secondary mechanism on the rear rod end, utilizing its equal 483N extend and retract forces for balanced motion.
Anti-Rotation Slides
The twin-rod design inherently resists torsion and provides superior load guidance, preventing the rod from twisting during precision vertical or horizontal sliding.
Through-Rod Sensing
Mounts a physical position flag or cam on the rear rod end to trigger external mechanical sensors without interfering with the primary work area on the front rod.
Is the Airtac SAID32 Double Rod Cylinder SAID32AX155S the Right Cylinder?
Select this 32mm bore double-rod cylinder when an application requires symmetric force, dual-side guidance, or rear-rod actuation that a single-rod SAI cannot provide. If you need less force, the neighboring 40mm bore offers 739N at 0.7 MPa, but the SAID32X155-S is optimal for lighter, precision-driven tasks. Keep in mind this cylinder does not hold its load if air pressure is lost; for position holding without live pressure, consider an external pilot-operated check valve or the BSAID clamp-lock series.
As a true ISO 15552 profile cylinder, it is dimensionally interchangeable with other ISO 15552 double-rod cylinders. Ensure your setup uses the SAID mounting accessory set (Basic, FA, LB, TC, FTC, TCM1, TCM2) and provides extra rear clearance for the protruding through-rod. Since the 155mm stroke exceeds the 50mm standard stroke increments, it is manufactured as a made-to-order non-standard stroke.

- ✓ 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 SAID32AX155S FAQ
Because it is a double-rod cylinder where the rod occupies both sides of the piston, the push and pull forces are equal. It generates 345N at 0.5 MPa, 483N at 0.7 MPa, and 621N at 0.9 MPa in both directions.
Yes, the SAID32X155-S is dimensionally interchangeable per ISO 15552 standards, acting as a direct replacement for other ISO 15552 double-rod profile cylinders. It uses PT tapered ports and a standard 32mm mounting interface.
