About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX145-100S
The AirTAC SAIJ32X145-100-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, delivering a 402N push force at 0.5 MPa. Its defining trait is a massive 100mm adjustment range, creating a usable travel window of 45-145mm. This allows operators to dial in the exact end position during commissioning without swapping hardware or adding external stops.
Built with a SUS304 stainless steel rod (option B), this model handles environments where standard carbon steel would corrode. The integrated magnet (-S) supports AirTAC CMSE reed and DMSE electronic sensors, fitting neatly into the dual-side sensor grooves of the extruded aluminum barrel. The rear adjuster acts purely as a travel stop for deceleration, meaning it will not hold a load without continuous live air pressure.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX145-100S Is Used
Variable End-Stop Tuning
Dial in the precise retract distance between 45 and 145mm during machine setup, perfect for testing different actuation depths on the fly.
Product Size Changeovers
Quickly adapt packaging lines to new container sizes by turning the rear adjuster, avoiding the need to physically swap out the entire cylinder.
Corrosion-Resistant Positioning
Leverage the SUS304 stainless steel rod for light-duty pushing tasks in washdown or mildly corrosive manufacturing environments.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX145-100S the Right Cylinder?
Choose this 32mm bore when an application demands extreme flexibility in end-position tuning, offering a 45-145mm window that far exceeds standard trim ranges. If your setup requires higher thrust, stepping up to the 40mm bore yields 628N of push force at 0.5 MPa. For load-holding without live air, a plain SAIJ is insufficient; you would need to specify a SAIL pneumatic lock or an external rod lock.
To match this exact ISO 15552 footprint for a direct replacement, confirm the 32mm bore, 145mm nominal stroke, 100mm adjustment code, PT tapered port threads, and the -S magnet. Because the nominal stroke is 145mm, side-load risks are minimal, but always ensure the M10x1.25 rod thread is aligned correctly to avoid binding.
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 SAIJ32BX145-100S FAQ
At 0.5 MPa, this 32mm bore cylinder provides 402N of push force and 345N of pull force. If operated at 0.7 MPa, the push force increases to 563N.
The rear adjuster allows you to shorten the effective stroke by up to 100mm. This creates a usable travel window of 45-145mm, letting you fine-tune the end position without changing the cylinder's physical mounting.
