About the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX375-20S
The AirTAC SAIJ100X375-20-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, providing a usable travel window of 355 to 375 mm. The extruded aluminum barrel features sensor grooves on both sides, and the integrated -S magnet operates seamlessly with AirTAC CMSE reed and DMSE electronic switches for exact end-of-stroke detection.
This model features a SUS420J2 stainless steel rod (code A) for enhanced corrosion resistance and utilizes PT tapered port threads. The rear adjustment screw allows you to fine-tune the retract end position during commissioning without adding external stops. Remember that this adjuster acts strictly as a travel stop, not a load lock; maintaining position requires continuous live air pressure.

Theoretical Output Force (Ø100mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 3682 N | 3682 N |
| 0.7 MPa | 5154 N | — |
| Max (@1.0 MPa) | 751 kgf | |
Double-rod model: the rod passes through the rear cover, so both piston faces lose rod area and push is shown at the annular-area value. Actual usable force is lower than theoretical due to friction and back-pressure. Size with a safety margin.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX375-20S Is Used
Variable End Stops
Dial in the exact 355 to 375 mm retract distance during machine setup to accommodate varying material lengths without swapping out the entire actuator.
Product Size Changeover
Quickly reconfigure the rear stroke stop on a packaging line when transitioning between different product sizes, minimizing downtime and mechanical adjustments.
Commissioning Fine-Tune
Trim the final 20 mm of travel during initial commissioning to perfectly align heavy 3927 N loads without relying on costly external mechanical stops.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX375-20S the Right Cylinder?
The adjustable 355-375 mm window is ideal for dialing in exact retraction distances on the fly. Because the nominal stroke is 375 mm, the M20x1.5 rod and long unsupported travel require an external guide to prevent excessive side-loading and premature seal wear.
For a direct ISO 15552 replacement match, ensure your specifications align with a 100 mm bore, 375 mm nominal stroke, 20 mm adjustment range, PT port threads, and the -S magnet option. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2, deliberately omitting FB, CA, CB, and CR configurations. If your application requires true load-holding without live air, consider the SAIL or BSAI series instead.
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 SAIJ100 Adjustable Cylinder SAIJ100AX375-20S FAQ
At 0.7 MPa, the push force increases to 5497 N.
The rear adjuster screw allows you to shorten the nominal 375 mm stroke by up to 20 mm, creating a usable travel window of 355 to 375 mm. This stopper fine-tunes the end position but does not lock the load without live air.
