About the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX240-75
The AirTAC SAIJ100X240-75 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that permits a usable travel window of 165 to 240 mm. The extruded aluminum barrel includes sensor grooves on both sides, though this specific configuration omits the magnet option.
This unit utilizes a SUS420J2 stainless steel rod for enhanced durability against lateral stress and features PT tapered port threads. The rear stopper allows you to fine-tune the end position at commissioning without swapping the cylinder or adding external stops. Remember that this adjuster acts solely as a travel stop to aid the air cushion deceleration; it does not lock the load without 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 SAIJ100AX240-75 Is Used
Machine Changeover
Dial in the exact end-stop distance during product size changes on a packaging line without physically swapping out the actuator.
Commissioning Tuning
Fine-tune the retract position by up to 75 mm during initial setup to perfect the mechanical timing of a heavy press assembly.
Variable End Stops
Adjust the travel window on the fly for sorting diverter arms that handle packages of varying lengths on a single belt.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX240-75 the Right Cylinder?
Select this 100 mm bore cylinder when your application requires substantial thrust—such as the 3927 N generated at 0.5 MPa—and demands a variable end-stop. If your setup only needs a fixed 240 mm stroke, the standard SAI cylinder is a simpler choice, but the SAIJ variant shines during machine changeovers where the stroke must be dialed back by up to 75 mm. To match this ISO 15552 replacement exactly, specify the 100 mm bore, 240 mm stroke, 75 mm adjustment, PT G1/2 port, and no magnet.
Because the 240 mm stroke is relatively long, ensure your mounting configuration—limited to Basic, FA, LB, TC, FTC, TCM1, or TCM2—provides adequate support. For load-holding without live pressure, this cylinder is insufficient; look to 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 SAIJ100AX240-75 FAQ
The rear adjuster acts as an external stop that lets you shorten the effective travel from the nominal 240 mm down to 165 mm. This allows precise end-position tuning at commissioning without adding external stops, though it does not hold the load without live air.
