About the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX225-75
The AirTAC SAIJ100X225-75 is a double-acting, double-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It provides a nominal 225 mm stroke that can be dialed back by up to 75 mm, yielding a precise 150 to 225 mm usable travel window for exact end-position tuning.
This unit features a SUS420J2 stainless steel rod for superior corrosion resistance and carries PT tapered port threads with a G1/2 connection. The extruded aluminum barrel includes sensor grooves on both sides for flexible switch placement. Because the rear screw acts strictly as a travel stop and not a lock, live air pressure is required to maintain the load position during operation.

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 SAIJ100AX225-75 Is Used
Product Changeovers
Dial in the 150-225 mm travel window during line format changes to accommodate different product sizes without replacing the cylinder.
Machine Setup
Fine-tune the retract end-position at commissioning to achieve exact stopping points for heavy 3927 N pressing or lifting tasks.
Variable End Stops
Use the rear adjuster screw to set deceleration points on the fly for automated machinery requiring flexible stroke limits.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX225-75 the Right Cylinder?
Select this 100 mm bore cylinder when an application requires heavy thrust combined with variable end-stops; if you need less force, stepping down to an 80 mm bore yields 2513 N at 0.5 MPa. The 75 mm adjustment range is ideal for product changeovers, allowing you to fine-tune the retract distance without swapping hardware or adding external stops. For load-holding without continuous air pressure, consider the SAIL or BSAI variants instead. To match this cylinder for an ISO 15552 replacement, verify the 225 mm stroke, 75 mm adjuster, PT port threads, and required mounting subset.
With a 225 mm stroke, the 25 mm rod diameter and M20x1.5 rod thread provide excellent rigidity, but any unsupported load over 300 mm still necessitates an external guide to prevent side-loading damage. SAIJ supports a reduced mounting set of Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR options.
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 SAIJ100AX225-75 FAQ
At 0.7 MPa, the push force increases to 5497 N.
The rear adjuster screw acts as a mechanical stop that shortens the effective travel. For this 225 mm stroke model, you can trim the retract distance by up to 75 mm, creating a usable travel window of 150 to 225 mm without changing the cylinder.
