About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX90-40
The AirTAC SAIJ32X90-40 is a double-acting, single-rod ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a nominal 90 mm stroke that can be dialed back by up to 40 mm, creating a precise 50-90 mm usable travel window for exact end-position tuning at commissioning. In the compact 32 mm bore class, it delivers 402 N of push force and 345 N of pull force at 0.5 MPa.
This model is configured with a SUS304 stainless steel rod for superior corrosion resistance and features PT tapered port threads. The extruded aluminum barrel includes sensor grooves on both sides, allowing for the direct mounting of AirTAC CMSE reed or DMSE electronic sensors if a magnet is specified later. The rear adjuster acts purely as a mechanical stop to set the travel end and does not hold the load without live air pressure.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX90-40 Is Used
Machine Changeover
Dial in the 50-90 mm travel window during product size transitions to set new retract positions rapidly without changing the cylinder.
End-Position Calibration
Fine-tune the exact end-of-stroke stopping point during machine commissioning using the rear adjuster screw instead of external shims.
Sensor Mounting Readiness
Utilize the dual-side sensor grooves on the extruded profile to easily add CMSE or DMSE switches for position feedback.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX90-40 the Right Cylinder?
Choose this 32 mm bore adjustable cylinder when an application requires fine-tuning the retract position without swapping components or adding external stops. If the 402 N push force at 0.5 MPa is insufficient, stepping up to the 40 mm bore yields 628 N. Unlike the fixed-stroke SAI, the SAIJ allows variable end-stops for product changeovers. For true load-holding without continuous air pressure, an external rod lock or a SAIL/BSAI variant is required. To match this ISO 15552 footprint, specify the 32 mm bore, 90 mm stroke, 40 mm adjustment, PT port thread, and the SUS304 rod material.

- ✓ 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 SAIJ32BX90-40 FAQ
At 0.5 MPa, this 32 mm bore cylinder provides 402 N of push force and 345 N of pull force. It operates at a speed range of 30-800 mm/s.
The rear adjuster screw allows you to shorten the 90 mm nominal stroke by up to 40 mm, providing a usable travel window of 50-90 mm. It functions as a mechanical stop and does not lock the load without air pressure.
