About the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX350-100
The AirTAC SAIJ80X350-100 is a double-acting ISO 15552 profile cylinder equipped with a rear mechanical adjuster, allowing you to fine-tune the end-of-travel position. With a nominal 350 mm stroke and a 100 mm adjustment range, it provides a usable travel window of 250 to 350 mm.
This unit features a SUS420J2 stainless steel rod (code A) for enhanced corrosion resistance and carries PT tapered port threads (G3/8). Because the stroke extends to 350 mm, the 25 mm rod diameter should be paired with an external guide to prevent excessive side-loading on the extruded aluminum barrel.

Theoretical Output Force (Ø80mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 2268 N | 2268 N |
| 0.7 MPa | 3175 N | — |
| Max (@1.0 MPa) | 463 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 SAIJ80 Adjustable Cylinder SAIJ80AX350-100 Is Used
Variable End-Stop Positioning
Dial in the exact retraction point between 250 mm and 350 mm during machine commissioning to accommodate different product sizes without external stopper blocks.
Product Changeover Systems
Quickly adjust the rear stroke stop on packaging conveyors to handle varying package lengths on the fly, minimizing downtime between production runs.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX350-100 the Right Cylinder?
The 100 mm adjustment window is ideal for product changeovers on a packaging line, letting you shift the end-stop from 350 mm down to 250 mm without swapping the cylinder or adding external stops. If you need to drop to a lighter load, a 63 mm bore offers 1402 N of pull force.
For ISO 15552 replacement matching, specify the 80 mm bore, 350 mm stroke, 100 mm adjustment, PT port thread, and standard mounting options (Basic, FA, LB, TC, FTC, TCM1, TCM2). Note that this SAIJ variant omits FB, CA, CB, and CR mounts. The rear adjuster acts strictly as a travel stop and does not hold the load without live air; for true load-holding, consider the SAIL or BSAI series. This model does not include a magnet for CMSE or DMSE sensors.
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 SAIJ80 Adjustable Cylinder SAIJ80AX350-100 FAQ
At the maximum 1.0 MPa pressure, it can deliver up to 513 kgf.
The rear adjuster screw allows you to shorten the effective travel from the nominal 350 mm down to 250 mm, creating a 250-350 mm usable window. It functions as a mechanical stop for end-position tuning and does not lock the load without continuous air pressure.
