About the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX750-20
The AirTAC SAIJ100X750-20 is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a nominal 750 mm travel that can be fine-tuned backward by up to 20 mm, yielding a precise 730-750 mm usable window. This allows exact end-position calibration at commissioning without external stops.
Because the 750 mm stroke is substantial, the 25 mm rod diameter and M20x1.5 rod thread provide necessary rigidity, though an external guide is still recommended for unsupported loads. The extruded aluminum barrel includes dual sensor grooves, but note this specific SKU lacks a magnet, so CMSE or DMSE switches cannot be used without a -S variant. The rear screw acts purely as a travel stop for deceleration, not a lock to hold the load without live air.

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 SAIJ100AX750-20 Is Used
Product Changeover
Dial in the 730-750 mm travel window during format size changes on packaging lines without physically swapping the actuator.
Variable End Stops
Adjust the stroke limit dynamically for automated assembly equipment requiring precise, high-force positioning at extended lengths.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX750-20 the Right Cylinder?
Select this 100 mm bore actuator when an application requires high thrust (up to 801 kgf at 1.0 MPa) alongside variable end-stop positioning. If 7068 N at 0.9 MPa exceeds your requirement, stepping down to an 80 mm bore yields 4523 N; conversely, a 125 mm bore provides 11045 N for heavier loads. The adjustable 730-750 mm window is ideal for product-size changeovers on a line, avoiding the need to swap cylinders.
For an exact ISO 15552 replacement, match the 100 mm bore, 750 mm stroke, 20 mm adjustment, PT port thread, and standard mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2). Note that FB, CA, CB, and CR mounts are omitted. If your process requires the load to be held without continuous air pressure, the standard rear adjuster will not suffice; consider an AirTAC SAIL or BSAI locking cylinder 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 SAIJ100AX750-20 FAQ
At the maximum 1.0 MPa pressure, it reaches 801 kgf.
The rear adjuster screw allows you to shorten the effective travel by up to 20 mm from the 750 mm nominal stroke, creating a 730-750 mm usable window. It functions as a physical stop for end-position tuning and does not lock the load without live air pressure.
