About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX150-100S
The AirTAC SAIJ32X150-100-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster. It delivers 402N of push force at 0.5 MPa and features a SUS304 stainless steel rod. The integrated rear stopper allows you to trim the nominal 150mm stroke back by up to 100mm, providing a wide 50-150mm usable travel window for highly flexible positioning.
This adjustable-stroke design eliminates the need to swap cylinders during machine changeovers. The rear adjuster acts purely as a travel stop to set the end position and does not hold the load without live air. It includes a magnet for CMSE and DMSE sensors, and the extruded aluminum barrel omits tie-rod construction.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX150-100S Is Used
Machine Changeovers
Dial in the exact end-stop for new product sizes without physically swapping the cylinder or adding external stopper blocks.
Variable End-Positioning
Utilize the 50-150mm travel window to fine-tune the retract position during commissioning for delicate assembly tasks.
Sensor-Ready Automation
The integrated magnet works directly with CMSE and DMSE switches for precise position feedback in compact pneumatic setups.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX150-100S the Right Cylinder?
Choose this 32mm bore when you need precise end-position tuning without adding external stops. If your application requires higher force, stepping up to the 40mm bore yields 628N of push force at 0.5MPa. The SAIJ32X150-100-S is selected over a fixed SAI model when a variable end-stop is required for product-size changes. Because the nominal stroke is 150mm, an external guide is recommended for side-load stability. For load-holding without live pressure, use an SAIL or BSAI cylinder instead of relying on the adjuster. To match this ISO 15552 replacement exactly, specify bore 32, stroke 150, 100mm adjustment, PT ports, and the -S magnet.

- ✓ 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 SAIJ32BX150-100S FAQ
At 0.5 MPa operating pressure, this 32mm bore cylinder provides 402N of push force and 345N of pull force. The maximum push force reaches 724N at 0.9 MPa.
The rear adjuster acts as a mechanical stop that can shorten the nominal 150mm stroke by up to 100mm, giving a usable travel window of 50-150mm. It sets the end position but does not lock the load without live air.
