About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX300-75S
The AirTAC SAIJ32X300-75-S is a double-acting, double-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It provides a nominal 300 mm stroke that can be fine-tuned backward by up to 75 mm, creating a precise 225-300 mm usable travel window for commissioning without external stops.
This model includes a piston magnet (-S) for direct compatibility with AirTAC CMSE reed and DMSE electronic sensors, which seat neatly into the dual-side sensor grooves of the extruded aluminum barrel. The rear adjuster functions strictly as a mechanical stop to set the end position and does not hold the load without live air pressure. For load-holding requirements, an external rod lock or an AirTAC SAIL pneumatic lock cylinder is required.

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 SAIJ32BX300-75S Is Used
Variable End-Stop Tuning
Dial in the exact 225 to 300 mm travel window during machine commissioning to perfect end-of-stroke positioning without swapping cylinders.
Product Size Changeover
Quickly adapt a packaging line for different carton lengths by turning the rear adjuster screw rather than re-engineering the mounting layout.
Stainless Rod Actuation
Leverage the SUS304 stainless steel rod for light-duty pushing in environments where moisture or minor corrosive elements are present.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX300-75S the Right Cylinder?
The 12 mm rod and M10x1.25 thread provide moderate side-load capacity, but with a 300 mm stroke, you should always guide the load externally to prevent rod binding. To match this ISO 15552 interchangeable cylinder, specify a 32 mm bore, 300 mm stroke, 75 mm adjustment range, PT tapered port thread, and a -S magnet.
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 SAIJ32BX300-75S FAQ
The rear adjuster acts as a mechanical stop that allows you to shorten the effective travel from 300 mm down to 225 mm. It is a travel stop, not a lock, so it cannot hold the load without live air pressure.
