About the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX175-100
The AirTAC SAIJ100X175-100 is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, allowing you to dial back the nominal 175 mm travel by up to 100 mm. This creates a highly flexible 75-175 mm usable stroke window, ideal for production lines running multiple product sizes. It delivers serious thrust, generating 3927 N of push force and 3681 N of pull force at 0.5 MPa.
This specific configuration features a SUS420J2 stainless steel rod for enhanced corrosion resistance and uses PT tapered port threads. The extruded aluminum barrel includes sensor grooves on both sides for direct mounting of CMSE reed or DMSE solid-state switches, though this particular SKU is specified without a magnet. The rear stopper acts purely as a travel-end deceleration device and does not hold the load without live air pressure.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX175-100 Is Used
Variable Product Changeover
Quickly reconfigure the 75-175 mm stroke window during product family changeovers on a packaging line, dialing in the exact end-stop without replacing hardware.
End-Position Commissioning
Fine-tune the retract position during machine setup to perfect part ejection or clamping distance, using the rear screw rather than shimming external stops.
Heavy-Duty Forming Stops
Leverage the 3927 N push force at 0.5 MPa for pressing or forming tasks where the exact material compression depth must be dialed in on the fly.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX175-100 the Right Cylinder?
Choose this 100 mm bore when an 80 mm bore falls short on power, as stepping up from the 80 mm (2513 N push at 0.5 MPa) to this 100 mm bore yields 3927 N. The massive 100 mm adjustment range is selected when a single station must handle extreme product size variations without physically swapping cylinders or adding external mechanical stops. To match this cylinder for an ISO 15552 replacement, specify the 100 mm bore, 175 mm stroke, 100 mm adjust, PT ports, and the SUS420J2 (A) rod material.
Because the 175 mm stroke is relatively short, side-loading is less of a concern than with longer strokes, but the 25 mm rod diameter still handles moderate bending loads well. For any application requiring the load to be physically locked in place without continuous air supply, this standard SAIJ adjuster is not a brake; you should instead look at the BSAI clamp-lock or SAIL pneumatic lock 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 SAIJ100 Adjustable Cylinder SAIJ100AX175-100 FAQ
At 0.5 MPa operating pressure, this 100 mm bore cylinder provides 3927 N of push force and 3681 N of pull force. If you need higher force, operating at 0.7 MPa yields 5497 N push, and the maximum rated force is 801 kgf at 1.0 MPa.
The rear adjuster acts as an external stopper that lets you mechanically shorten the 175 mm nominal stroke by up to 100 mm, giving a usable travel window of 75-175 mm. It decelerates the travel end but does not lock the load without live air pressure.
