About the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX475-40S
The AirTAC SAIJ32X475-40-S is a double-acting, single-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It provides a 435-475mm usable travel window, allowing you to dial back the 475mm nominal stroke by up to 40mm during commissioning. Delivering 402N of push force at 0.5 MPa, it suits lighter-duty tasks requiring precise end-position tuning.
This SKU features a SUS420J2 stainless steel rod (material code A) for enhanced corrosion resistance compared to standard carbon steel. The integrated magnet (-S) supports position sensing via AirTAC CMSE reed or DMSE electronic solid-state switches fitted into the dual-side sensor grooves. Fluid ports are PT tapered G1/8 threads.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX475-40S Is Used
Product Changeover
Quickly fine-tune the 435-475mm travel window during machine format changes without swapping out the entire cylinder.
Variable End Stops
Ideal for diverter gates on conveyors where the retracted position needs occasional adjustment to accommodate different package sizes.
Machine Setup
Allows precise rear-end position calibration at commissioning, preventing hard mechanical crashes during initial cycling.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX475-40S the Right Cylinder?
Choose this 32mm bore when an application demands exact end-stop tuning without external shims; it provides 402N push and 345N pull force at 0.5 MPa. If your setup requires greater thrust, stepping up to the 40mm bore yields 628N push force. Conversely, if you need a basic fixed stroke without the rear adjuster, the standard SAI series is a simpler alternative.
Because the 475mm stroke is relatively long for a 32mm bore, external guiding is recommended to prevent excessive side-loading on the 12mm rod and M10x1.25 rod thread. The rear adjuster acts strictly as a travel stop and does not hold the load without live air; for fail-safe load holding, consider the SAIL or BSAI series. This model is dimensionally interchangeable per ISO 15552 and uses the reduced SAIJ mounting set: Basic, FA, LB, TC, FTC, TCM1, and TCM2.

- ✓ 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 SAIJ32AX475-40S FAQ
At 0.5 MPa operating pressure, this 32mm bore cylinder provides 402N of push force and 345N of pull force. It can reach a maximum push force of 724N at 0.9 MPa.
The rear adjuster screw lets you shorten the effective stroke by up to 40mm, creating a usable travel window of 435-475mm. The adjuster functions as a mechanical stop to set the end position and does not lock the load without continuous air pressure.
