About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX450-30S
The AirTAC SAIJ32X450-30-S is a double-acting, single-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It provides a 420-450 mm usable travel window, letting you dial back the 450 mm nominal stroke by up to 30 mm during commissioning without adding external stops. Delivering 402 N of push force at 0.5 MPa, it suits lighter-duty positioning tasks.
This SKU is built with a SUS304 stainless steel rod for corrosion resistance and includes a magnet for CMSE reed and DMSE electronic sensors. The extruded aluminum barrel features sensor grooves on both sides. It uses a G1/8 port and M10x1.25 rod thread, while the 12 mm rod handles moderate side loads effectively.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX450-30S Is Used
Machine Setup Changeover
Fine-tune the 420-450 mm travel window during product size changes without physically swapping the cylinder or repositioning external hard stops.
Variable End-Stop Positioning
Adjust the retract position on the fly to accommodate varying package lengths on a conveyor handling line, using the 30 mm rear adjuster.
Corrosive Environment Testing
Leverage the SUS304 stainless steel rod for repeatable actuation in test chambers or environments where standard carbon steel rods would degrade.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX450-30S the Right Cylinder?
Select this 32 mm bore when an application requires fine-tuning the retract end-position on a 450 mm stroke, delivering 402 N push force at 0.5 MPa. If your process needs higher thrust, stepping up to the 40 mm bore yields 628 N at the same pressure. The rear adjuster acts purely as a travel stop and cannot hold a load without live air; for true fail-safe load holding, consider the SAIL or BSAI series.
As a dimensionally interchangeable ISO 15552 profile cylinder, this model replaces units matching a 32 mm bore, 450 mm stroke, and 30 mm adjustment. Ensure your setup specifies PT tapered ports, the reduced SAIJ mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2), and a -S magnet. Because the stroke is 450 mm, use an external guide to prevent rod binding under heavy lateral loads.

- ✓ 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 SAIJ32BX450-30S FAQ
At 0.5 MPa it provides 402 N of push force and 345 N of pull force. The operational speed range is 30-800 mm/s.
The rear adjuster screw lets you shorten the 450 mm nominal stroke by up to 30 mm, providing a usable travel window of 420-450 mm. It functions as a mechanical stop and does not lock the load without air pressure.
