About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX180-30S
The AirTAC SAIJ32X180-30-S is a double-acting, single-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It provides a nominal 180 mm stroke that can be fine-tuned backward by up to 30 mm, yielding a usable travel window of 150-180 mm. In the 32 mm bore class, it delivers 402 N of push force and 345 N of pull force at 0.5 MPa.
This specific configuration includes a SUS304 stainless steel rod (option B) for superior corrosion resistance and features a built-in magnet (-S) for use with AirTAC CMSE reed and DMSE electronic sensors. The rear adjuster acts purely as a mechanical stop to set the end position during commissioning; it does not lock the load without live air pressure.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX180-30S Is Used
Product Changeover
Dial in the 150-180 mm travel window during format changes on packaging lines, allowing rapid adjustment without replacing the cylinder or adding external stopper blocks.
End-Position Tuning
Fine-tune the retract stroke end during machine commissioning to perfectly seat parts, using the rear screw to absorb minor mechanical tolerances.
Sensor-Ready Positioning
Leverage the integrated magnet with DMSE electronic sensors to confirm the adjusted end position, ensuring precise signal feedback in automated assembly.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX180-30S the Right Cylinder?
Choose this 32 mm bore cylinder when an application requires precise end-position tuning at commissioning or frequent product-size changeovers, avoiding the need to swap out a fixed-stroke SAI cylinder. If your setup needs less force, stepping down is not an option below 32 mm in this series, but stepping up to a 40 mm bore yields 628 N of push force at 0.5 MPa. Because this unit has a 180 mm stroke, which is under the 300 mm threshold, extreme side-loading is less of a concern, but the 12 mm rod still requires external guidance for heavy lateral loads.
To match this exact ISO 15552 interchangeable cylinder, specify: 32 mm bore, 180 mm stroke, 30 mm adjustment range, PT tapered port thread, SUS304 rod material, and the -S magnet option. Remember that the rear adjuster is a travel stop, not a lock; for load-holding without live air, consider an AirTAC SAIL or BSAI cylinder. Mounting options include Basic, FA, LB, TC, FTC, TCM1, and TCM2.
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 SAIJ32BX180-30S FAQ
At 0.5 MPa operating pressure, this 32 mm bore cylinder generates 402 N of push force and 345 N of pull force. At its maximum 1.0 MPa pressure, it can deliver up to 82 kgf.
The rear adjuster allows you to shorten the effective stroke by up to 30 mm from the nominal 180 mm, providing a usable travel window of 150-180 mm. It functions as a mechanical stop for end-position tuning and does not lock the load without continuous air pressure.
