About the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX260-40
The AirTAC SAIJ100X260-40 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that creates a 220-260 mm usable travel window. The extruded aluminum barrel includes sensor grooves on both sides for flexible switch mounting.
This variant uses an SUS420J2 stainless steel rod for enhanced corrosion resistance and ships with PT tapered port threads (G1/2). The rear stopper screw lets you fine-tune the retract end position during commissioning without adding external stops. Note that the adjuster acts purely as a travel stop and does not hold 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 SAIJ100AX260-40 Is Used
Machine Setup Changeover
Dial in the 220-260 mm travel window during product size changes without physically replacing the cylinder or bolting on external stopper blocks.
Variable End-Stop Positioning
Use the 40 mm rear adjustment screw to set precise retract positions for multi-format packaging lines, accommodating different package depths on the fly.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX260-40 the Right Cylinder?
The adjustable 40 mm window is ideal for product changeovers, allowing you to dial in the exact end-stop without swapping the cylinder for a fixed-stroke SAI model. Mounting options include Basic, FA, LB, TC, FTC, TCM1, and TCM2.
Because the 260 mm stroke exceeds 300 mm is not the case here, but always ensure adequate guiding for the 25 mm rod on long strokes. For applications requiring the load to be held mechanically without continuous air pressure, select a SAIL or BSAI cylinder instead, as the SAIJ adjuster is not a locking device.
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 SAIJ100AX260-40 FAQ
At the maximum 1.0 MPa pressure, it achieves 801 kgf.
The rear adjuster screw allows you to shorten the nominal 260 mm stroke by up to 40 mm, creating a usable travel range of 220 to 260 mm. It functions as a mechanical stop for end-position tuning and is not a locking device.
