About the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX375-100S
The AirTAC SAIJ32X375-100-S is a double-acting, single-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It delivers 402N of push force at 0.5 MPa and features a 375mm nominal stroke that can be fine-tuned down by up to 100mm, creating a precise 275-375mm usable travel window. This built-in adjustability allows operators to dial in exact end positions during commissioning without adding external stops.
This model includes an SUS420J2 stainless steel rod (code A) for improved corrosion resistance and carries a PT tapered port thread. The extruded aluminum barrel features sensor grooves on both sides, and the included magnet (-S) integrates seamlessly with AirTAC CMSE reed and DMSE electronic solid-state switches. It utilizes variable air cushions at both ends to decelerate the moving load smoothly.

Where the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX375-100S Is Used
Product Changeovers
Quickly adjust the 275-375mm travel window to accommodate different package sizes on a packaging line without swapping hardware.
Machine Setup
Fine-tune the retract end-position during initial commissioning to achieve precise alignment without machining external stopper blocks.
Variable End Stops
Dial in the exact rejection distance for moving products on a conveyor, relying on the 100mm rear stopper to set the final position.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX375-100S the Right Cylinder?
Choose this 32mm bore when an application requires 402N push force at 0.5 MPa but demands variable end-stops for frequent product changeovers. If your setup needs less force, stepping down is not an option in this size range, but if you need greater thrust, the 40mm bore provides 628N. Because the total stroke is 375mm, an external guide is recommended to prevent excessive side-loading on the 12mm rod. The rear adjuster acts strictly as a travel stop and does not hold the load without live air; for true position holding, consider the SAIL or BSAI series.
To match this exact ISO 15552 interchangeable cylinder, specify: 32mm bore, 375mm stroke, 100mm adjustment, PT port thread, SUS420J2 rod, and the -S magnet. It supports a mounting subset of Basic, FA, LB, TC, FTC, TCM1, and TCM2 (omitting FB, CA, CB, and CR). Operating speed ranges from 30-800mm/s.

- ✓ 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 SAIJ32AX375-100S FAQ
At 0.5 MPa operating pressure, this 32mm bore cylinder provides 402N of push force and 345N of pull force. At 0.7 MPa, the push force increases to 563N.
The rear adjuster screw allows you to trim the effective stroke by up to 100mm. This creates a usable travel window of 275-375mm from the 375mm nominal stroke, enabling fine-tuning of the end position without replacing the cylinder.
