About the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX750-40S
The AirTAC SAIJ100X750-40-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, providing a usable travel window of 710 to 750 mm. The integrated -S magnet supports AirTAC CMSE reed and DMSE electronic sensors housed within the dual-side barrel grooves.
This adjustable-stroke design allows precise end-position tuning during commissioning without swapping the cylinder or adding external stops. The rear adjuster functions strictly as a travel stop, meaning it cannot hold a load without live air pressure. It utilizes a PT tapered port thread and includes variable air cushions at both ends to manage deceleration across its 30-800 mm/s operating speed range.

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 SAIJ100AX750-40S Is Used
Variable End-Stop Tuning
Dial in the exact 710 to 750 mm end position during machine setup to accommodate varying product lengths without mechanical rework.
Heavy-Duty Positioning
Leverage the 100 mm bore and SUS420J2 stainless rod for robust positioning tasks in demanding industrial environments.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX750-40S the Right Cylinder?
The 40 mm adjustment range is ideal for fine-tuning machinery during product changeovers. For load-holding without continuous air pressure, consider an external rod lock or the AirTAC SAIL/BSAI series, as the SAIJ adjuster is not a locking device. To replace an ISO 15552 cylinder, match the 100 mm bore, 750 mm stroke, PT port, and -S magnet.
Because the 750 mm stroke is substantial, the 25 mm rod diameter requires external guiding to prevent excessive side-loading and premature seal wear. Mounting options include Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR configurations.
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 SAIJ100AX750-40S FAQ
At 0.7 MPa, the push force increases to 5497 N.
The rear adjuster acts as a mechanical stop, allowing you to shorten the effective travel from the nominal 750 mm down to 710 mm. It decelerates the stroke end but does not lock the load without live air pressure.
