About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX90-40S
The AirTAC SAIJ32X90-40-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, providing a usable travel window of 50-90 mm from its 90 mm nominal stroke. It delivers 402 N of push force and 345 N of pull force at 0.5 MPa, utilizing a 12 mm SUS304 stainless steel rod and PT tapered port threading. The integrated magnet (-S) supports position sensing with AirTAC CMSE reed and DMSE electronic switches mounted in the dual-side sensor grooves.
This adjustable model allows precise end-position tuning at commissioning without adding external stops or swapping cylinders. It uses a reduced mounting set of Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR brackets. The rear adjuster functions strictly as a mechanical stop for travel deceleration and does not lock or hold the load without live air pressure.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX90-40S Is Used
Machine Setup Tuning
Dial in the exact 50-90 mm travel window during commissioning to perfect end-stop positions without machining custom spacers.
Product Changeover
Quickly adapt end positions on a packaging line for different product sizes by turning the rear adjuster screw.
Assembly Pressing
Provide precise variable end-stops for light-duty pressing tasks requiring 402 N of force at 0.5 MPa.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX90-40S the Right Cylinder?
Choose this 32 mm bore when an application requires 402 N of push force at 0.5 MPa, stepping down from a 40 mm bore that offers 628 N, or up if more thrust is needed. An adjustable stroke is selected over a fixed SAI cylinder to fine-tune variable end stops during machine setup or product changeover. For load-holding without continuous live air pressure, this cylinder is insufficient as the rear adjuster is only a stop; consider an external rod lock, a pilot-operated check valve, or AirTAC SAIL and BSAI locking cylinders. To match this ISO 15552 replacement, specify the 32 mm bore, 90 mm stroke, 40 mm adjustment, PT port, and the -S magnet.

- ✓ 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 SAIJ32BX90-40S FAQ
The rear adjuster acts as a mechanical stop, allowing you to trim the 90 mm nominal stroke back by up to 40 mm, creating a usable travel window of 50-90 mm. It sets the end position but does not hold the load without live air.
At 0.5 MPa, it provides 402 N of push force and 345 N of pull force. At 0.7 MPa, the push force increases to 563 N.
