About the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX185-10
The AirTAC SAIJ32X185-10 is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster. It provides a 12mm piston rod and a usable travel window of 175-185mm, allowing you to dial back the nominal 185mm stroke by up to 10mm. This bore size yields 402N of push force at 0.5 MPa and up to 724N at 0.9 MPa.
The barrel is extruded aluminum with sensor grooves on both sides. The piston rod utilizes SUS420J2 stainless steel for improved corrosion resistance, and the fluid port features a PT tapered thread. You can fine-tune end positions at commissioning without bolting on external stops or swapping the cylinder.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX185-10 Is Used
Machine Changeovers
Fine-tune the retract end position by up to 10mm during product size changes without replacing the cylinder or adding external stopper blocks.
End-Position Tuning
Dial in the exact 175-185mm travel window during commissioning to accommodate mechanical tolerances and achieve precise sensor triggering.
Variable End Stops
Adjust the stroke on packaging lines to handle slightly different carton lengths using the rear screw stopper mechanism.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX185-10 the Right Cylinder?
Choose this 32mm bore adjustable-stroke cylinder when your setup requires precise end-position tuning during machine changeovers. If your application demands higher force, stepping up to the 40mm bore provides 628N of push force at 0.5 MPa. The rear adjuster acts purely as a travel stop to set deceleration, not a lock; a plain SAIJ does not hold loads without live air, so for fail-safe load holding, consider the SAIL or BSAI series. To match this ISO 15552 interchangeable cylinder, specify the 32mm bore, 185mm stroke, 10mm adjustment, PT G1/8 port, and no magnet.

- ✓ 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 SAIJ32AX185-10 FAQ
At 0.5 MPa, this 32mm bore cylinder provides 402N of push force and 345N of pull force. At 0.9 MPa, the push force increases to 724N.
The rear adjuster screw lets you shorten the effective travel from the 185mm nominal stroke down to 175mm, providing a 175-185mm usable window for fine-tuning the retract end position.
