About the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX45-10S
The AirTAC SAIJ32X45-10-S is a double-acting, single-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It provides a nominal 45 mm stroke that can be fine-tuned backward by up to 10 mm, creating a precise 35-45 mm usable travel window for exact end-positioning. Delivering 402 N of push force at 0.5 MPa, it fits compact actuation needs perfectly.
This variant features a SUS304 stainless steel rod for corrosion resistance and includes a piston magnet (-S) for position sensing. It supports AirTAC CMSE reed and DMSE electronic solid-state switches mounted in the dual-side sensor grooves of the extruded aluminum barrel. Fluid supply connects via PT G1/8 tapered ports.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX45-10S Is Used
End-Stop Calibration
Dial in the exact 35-45 mm retract position during machine setup without installing external physical stops on the fixture.
Product Changeover
Quickly adapt the cylinder's effective travel window on a packaging line when switching between slightly different material lengths.
Corrosive Positioning
Leverage the SUS304 stainless steel rod for precise component positioning in environments requiring higher corrosion resistance.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32BX45-10S the Right Cylinder?
Choose this 32 mm bore when your application requires 402 N push force at 0.5 MPa and exact end-stop tuning is critical; step up to the 40 mm bore if you need 628 N of force. The rear adjuster allows you to dial in the retract position during commissioning or product changeover without swapping cylinders or adding external stops. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR.
For ISO 15552 replacement matching, specify bore 32, stroke 45, adjustment 10, PT G1/8 ports, and the -S magnet. Remember that the rear adjuster acts only as a travel stop and does not hold the load without live air pressure; for dead-stop holding, consider an external rod lock or the SAIL/BSAI 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 SAIJ32BX45-10S FAQ
At 0.5 MPa operating pressure, this 32 mm bore cylinder provides 402 N of push force and 345 N of pull force. At the maximum 1.0 MPa pressure, it delivers up to 82 kgf.
The rear adjuster screw allows you to shorten the nominal 45 mm stroke by up to 10 mm, providing a usable travel window of 35-45 mm. This stopper fine-tunes the end position but does not lock the load without continuous air pressure.
