About the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX260-20
Its defining feature is the external adjusting screw, which provides a usable travel window of 240-260 mm. This allows precise end-position tuning at commissioning without swapping the cylinder or adding external stops.
This model features a SUS420J2 stainless steel rod (material code A) for enhanced corrosion resistance and uses a PT tapered port thread. The extruded aluminum barrel includes sensor grooves on both sides. While it lacks a standard magnet, it retains the standard ISO 15552 mounting interface and variable air cushions at both ends to decelerate the load smoothly.

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 SAIJ100AX260-20 Is Used
Product Changeovers
Quickly dial the stroke back by up to 20mm when switching between product sizes on the line, avoiding the need to physically swap out the entire actuator.
End-Stop Tuning
Fine-tune the retracted position during machine commissioning to achieve perfect alignment without adding external mechanical stops.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX260-20 the Right Cylinder?
The 20mm rear adjuster is ideal for product-size changeovers on a line, allowing operators to dial in the exact end-stop without mechanical modifications. If fixed travel is sufficient, a standard SAI cylinder simplifies the setup.
Because the stroke is 260mm, an external guide is recommended to support the rod and prevent excessive side-loading. Remember that the rear adjuster acts only as a travel stop and does not hold the load without live air; for fail-safe load holding, consider the SAIL or BSAI series. This unit is dimensionally interchangeable per ISO 15552, using PT ports and the SAIJ mounting subset (Basic, FA, LB, TC, FTC, TCM1, TCM2).
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 SAIJ100AX260-20 FAQ
The rear adjusting screw acts as a mechanical stopper, allowing you to shorten the effective stroke from its nominal 260mm down to 240mm. This stopper only sets the travel end and does not lock the load without live air pressure.
