Airtac Adjustable Cylinder SAIJ32 SAIJ32AX180-30
The AirTAC Airtac Adjustable Cylinder SAIJ32 SAIJ32AX180-30 is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø32mm bore and 180mm stroke, G1/8 air ports and adjustable end cushioning. Its standardized mounting interface makes it a drop-in replacement for other ISO 15552 cylinders in automation lines.

About the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX180-30
The AirTAC SAIJ32X180-30 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that creates a 150-180 mm usable travel window. Delivering 563 N of push force at 0.7 MPa, it is built with a SUS420J2 stainless steel rod for improved corrosion resistance. The extruded aluminum barrel includes sensor grooves on both sides for flexible mounting of CMSE or DMSE switches.
Equipped with PT tapered port threads and a G1/8 air supply port, this 32 mm bore model uses a 12 mm rod with an M10x1.25 thread. The rear adjuster acts purely as a mechanical stop to trim the retract position, meaning it does not hold the load without live air pressure. For true load-holding requirements, consider the SAIL or BSAI series instead.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX180-30 Is Used
Machine Changeover
Dial in the 150-180 mm travel window during product size changeovers to set precise retract positions without swapping hardware.
End-Stop Tuning
Fine-tune the final retract position during machine commissioning to compensate for mechanical tolerances using the rear adjuster.
Variable Positioning
Set custom retract limits on automated lines where the exact end position varies slightly between different workpieces.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX180-30 the Right Cylinder?
Select this 32 mm bore cylinder when your application requires fine-tuning the end-of-stroke position during commissioning without adding external stops. If your setup needs slightly less force, stepping down is an option, but stepping up to a 40 mm bore yields 879 N of push force at 0.5 MPa for heavier loads. The SAIJ32X180-30 uses PT tapered port threads and omits the FB, CA, CB, and CR mounting styles, supporting only Basic, FA, LB, TC, FTC, TCM1, and TCM2 mounts.
Because the nominal stroke is 180 mm, side-load risks are minimal, but always ensure proper alignment. The rear screw adjuster is a travel stop, not a locking mechanism. To replace an ISO 15552 cylinder, match the 32 mm bore, 180 mm stroke, 30 mm adjustment, G1/8 PT port, and desired mounting kit.
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 Adjustable Cylinder SAIJ32 SAIJ32AX180-30 FAQ
At 0.7 MPa operating pressure, this 32 mm bore cylinder provides 563 N of push force and 506 N of pull force. The maximum operating pressure is 1.0 MPa.
The rear adjuster screw allows you to shorten the effective stroke by up to 30 mm, creating a 150-180 mm usable travel window. It functions as a mechanical stop and does not lock the load without live air pressure.
