About the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX450-10
The AirTAC SAIJ32X450-10 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that creates a 440-450mm usable travel window. Delivering 402N of push force at 0.5MPa, it uses a SUS420J2 stainless steel rod for improved corrosion resistance. The extruded aluminum barrel includes sensor grooves on both sides for flexible switch placement.
Equipped with PT tapered port threading and a G1/8 air supply connection, this unit achieves standard speeds of 30-800mm/s. The rear stopper screw allows you to fine-tune the retract end position by up to 10mm during commissioning without adding external stops. This adjuster acts purely as a travel limiter and does not hold the load without live air pressure.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX450-10 Is Used
End-Position Tuning
Dial in the exact retract distance within the 440-450mm window during machine commissioning to perfect product handling without external stopper blocks.
Product Changeover
Quickly adjust the travel end-stop on packaging lines when switching between slightly different package sizes, minimizing downtime.
Sorting Diverter
Precisely set the rejection stroke on a conveyor belt system to push varying product profiles accurately into sorting bins.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX450-10 the Right Cylinder?
Choose this 32mm bore when you need lighter force (402N at 0.5MPa) and step up to the 40mm bore if your application requires 628N. The 10mm adjustment range is ideal for dialing in exact end positions during machine setup or product changeover, avoiding the need to physically swap a fixed-stroke SAI cylinder. If your process demands true load-holding without continuous air pressure, consider the SAIL or BSAI locking cylinder series instead.
With a 450mm stroke, the 12mm rod and M10x1.25 thread provide a robust interface, but long unsupported strokes still require an external guide to prevent side-loading damage. This SAIJ model supports a reduced mounting set including Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR brackets. It is dimensionally interchangeable per ISO 15552 mounting interfaces.

- ✓ 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 SAIJ32AX450-10 FAQ
At 0.5MPa operating pressure, this 32mm bore cylinder provides 402N of push force and 345N of pull force. The maximum thrust is 82kgf at 1.0MPa.
The rear adjuster screw allows you to shorten the nominal 450mm stroke by up to 10mm, creating a 440-450mm travel window. This stopper only limits the travel end and does not lock or hold the load without live air pressure.
