About the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX475-40
The AirTAC SAIJ32X475-40 is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a usable travel window of 435 to 475 mm, allowing you to dial back the nominal 475 mm stroke by up to 40 mm during machine commissioning without swapping hardware.
This SKU is configured with a SUS420J2 stainless steel rod for enhanced corrosion resistance and utilizes a PT tapered port thread. The extruded aluminum barrel includes sensor grooves on both sides for flexible mounting of CMSE reed or DMSE electronic switches. Note that the rear adjuster acts purely as a travel stop and does not hold the load without live air pressure.

Theoretical Output Force (Ø32mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 346 N | 346 N |
| 0.7 MPa | 484 N | — |
| Max (@1.0 MPa) | 70 kgf | |
Double-rod model: the rod passes through the rear cover, so both piston faces lose rod area and push is shown at the annular-area value. Actual usable force is lower than theoretical due to friction and back-pressure. Size with a safety margin.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX475-40 Is Used
End-Position Tuning
Fine-tune the retract stroke by up to 40 mm during machine setup to perfect a 435-475 mm travel window without adding external mechanical stops.
Product Changeovers
Rapidly adapt end-stops on a production line when handling slightly different package sizes, using the rear adjuster to shift the 475 mm nominal stroke.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX475-40 the Right Cylinder?
The adjustable rear stopper is ideal for product changeovers where exact end-stops vary, functioning differently than a fixed-stroke SAI cylinder. Because the 475 mm stroke is relatively long for a 32mm bore, an external guide is recommended to prevent excessive side-loading on the 12mm rod and M10x1.25 thread.
When specifying an ISO 15552 replacement, match the 32mm bore, 475mm nominal stroke, 40mm adjustment range, PT port thread, and the SUS420J2 (A) rod material. The mounting interface supports Basic, FA, LB, TC, FTC, TCM1, and TCM2 accessories. For applications requiring the load to be held without live air, select the SAIL or BSAI series instead, as the SAIJ adjuster is not a locking mechanism.
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 SAIJ32AX475-40 FAQ
At the maximum 1.0 MPa pressure, it can output up to 82 kgf.
The rear adjuster acts as an external stopper that shortens the effective stroke. For the SAIJ32X475-40, you can trim the 475mm nominal stroke back by up to 40mm, creating a usable travel window of 435 to 475mm. It functions as a stop, not a lock, so it will not hold the load without live air pressure.
