About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX145-30
The AirTAC SAIJ32X145-30 is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a usable travel window of 115 to 145 mm, allowing you to dial in the exact retract position without swapping components. Equipped with a SUS304 stainless steel rod and PT tapered ports, it delivers a push force of 402 N and a pull force of 345 N at 0.5 MPa.
This adjustable-stroke design allows fine end-position tuning at commissioning without adding external stops. The rear adjuster functions purely as a travel stop and does not hold the load without live air pressure. It supports AirTAC CMSE reed and DMSE electronic sensors via side-mounted grooves, and uses a reduced mounting subset of Basic, FA, LB, TC, FTC, TCM1, and TCM2.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX145-30 Is Used
Machine Setup Tuning
Dial in the exact 115-145 mm retract position during commissioning to perfect part ejection without machining external stop blocks.
Product Changeovers
Quickly adapt the stroke end-stop on a packaging line when handling different carton sizes, using the 30 mm adjustment range.
Precise End-Positioning
Achieve accurate end-of-stroke tuning for low-force assembly tasks, relying on the 12 mm rod and M10x1.25 thread for stable operation.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX145-30 the Right Cylinder?
Choose this 32 mm bore when your application requires 402 N of push force at 0.5 MPa. If your process needs less than 345 N of pull force, consider stepping down to a smaller bore, or step up to a 40 mm bore (628 N push) for heavier loads. The 30 mm adjustment range is perfect for product changeovers on a line, letting you vary the end-stop dynamically rather than committing to a fixed-stroke SAI cylinder.
Because the nominal stroke is 145 mm, side-load risks are minimal, but always guide rigid loads to prevent rod binding. Remember that the rear adjuster only sets the travel end; for true load-holding without live air, select an SAIL or BSAI cylinder. This SAIJ model is dimensionally interchangeable per ISO 15552.
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 SAIJ32BX145-30 FAQ
At 0.5 MPa operating pressure, this 32 mm bore cylinder provides a push force of 402 N and a pull force of 345 N. The maximum push force is 724 N at 0.9 MPa.
The rear adjuster lets you shorten the 145 mm nominal stroke by up to 30 mm, creating a usable travel window of 115 to 145 mm. It acts as a mechanical stop to set the end position and does not lock the load without continuous air pressure.
