About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX150-40S
The AirTAC SAIJ32X150-40-S is a double-acting, single-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It provides a 110-150 mm usable travel window, allowing you to trim the 150 mm nominal stroke by up to 40 mm during commissioning. Delivering 402 N of push force at 0.5 MPa, it suits light-duty positioning tasks.
This variant features a SUS304 stainless steel rod for superior corrosion resistance and includes a magnet for CMSE reed and DMSE electronic sensors. The extruded aluminum barrel maintains standard ISO 15552 mounting dimensions while omitting the FB, CA, CB, and CR bracket options found on some models.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX150-40S Is Used
End-Position Tuning
Dial in the exact retract distance within the 110-150 mm window during machine setup to accommodate varying material thicknesses without swapping cylinders.
Product Changeover
Quickly adjust the stroke by up to 40 mm on packaging lines when switching between different product sizes, minimizing downtime.
Light-Duty Positioning
Leverage the 402 N push force and SUS304 rod for precise, corrosion-resistant component placement in automated assembly fixtures.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX150-40S the Right Cylinder?
Select this 32 mm bore when an application requires precise end-position tuning without adding external stops, stepping up from smaller actuators or down from a 40 mm bore that yields 628 N push force at 0.5 MPa. The adjustable stroke is perfect for product changeovers, but note the rear screw acts only as a travel stop; it does not hold the load without live air. For load-holding, consider an external rod lock or a SAIL cylinder.
Because the 150 mm stroke is under the 300 mm threshold, side-load risks are minimal, though the 12 mm rod still requires alignment. To match this ISO 15552 replacement exactly, specify the PT tapered port, SUS304 (B) rod material, and the -S magnet option.
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 SAIJ32BX150-40S FAQ
The rear adjuster screw acts as a mechanical stop, allowing you to shorten the effective stroke by up to 40 mm. This creates a 110-150 mm usable travel window for fine-tuning at commissioning, though it does not lock the position without continuous air pressure.
At 0.5 MPa operating pressure, this 32 mm bore cylinder provides 402 N of push force and 345 N of pull force. It can reach a maximum push force of 724 N at 0.9 MPa.
