About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX150-30S
The AirTAC SAIJ32X150-30-S is a double-acting, single-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It provides a nominal 150 mm stroke that can be fine-tuned down by up to 30 mm, giving you a usable travel window of 120-150 mm. In the 32 mm bore class, it delivers 563 N of push force at 0.7 MPa, making it well-suited for lighter-duty positioning tasks.
This variant features a SUS304 stainless steel rod for superior corrosion resistance and includes a magnet for CMSE and DMSE sensors. The extruded aluminum barrel includes sensor grooves on both sides, and the PT tapered port threads match the standard G1/8 porting for this bore size.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX150-30S Is Used
Machine Changeover
Dial in the 120-150 mm travel window during product size changes without adding external stopper blocks to the machine frame.
End-Position Tuning
Fine-tune the retract distance at commissioning to achieve exact positioning, compensating for mechanical tolerances on the line.
Sensor-Ready Actuation
Leverage the integrated magnet with DMSE solid-state or CMSE reed switches to confirm the adjusted end-of-stroke position.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX150-30S the Right Cylinder?
Choose this 32 mm bore when an application requires precise end-position tuning during commissioning or product changeover without swapping out the entire cylinder. If your setup needs more power, stepping up to the 40 mm bore yields 879 N of push force at 0.5 MPa. Because the 150 mm stroke is relatively short, side-load risks are minimal, but always ensure the load is guided externally. For drop-in compatibility, match the 32 mm bore, 150 mm stroke, 30 mm adjustment, PT port thread, and the -S magnet requirement.
Remember that the rear adjuster acts strictly as a mechanical stop to set the travel end, not as a locking device. The cylinder cannot hold a load without continuous live air pressure; if true load-holding is required, consider an external rod lock or the AirTAC SAIL series.
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 SAIJ32BX150-30S FAQ
At 0.7 MPa operating pressure, this 32 mm bore cylinder provides 563 N of push force and 482 N of pull force. It can reach a maximum push force of 724 N at 0.9 MPa.
The rear adjuster screw allows you to shorten the effective stroke by up to 30 mm. This creates a usable travel window of 120-150 mm from the nominal 150 mm stroke, enabling fine-tuning at commissioning without replacing the cylinder.
