About the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX475-100S
The AirTAC SAIJ100X475-100-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster. It provides a 375-475 mm usable travel window from its 475 mm nominal stroke, allowing precise end-position tuning without swapping the unit.
This variant features a SUS420J2 stainless steel rod for superior corrosion resistance and includes a magnet for CMSE and DMSE sensors. The extruded aluminum barrel includes sensor grooves on both sides, and the rear adjuster acts purely as a travel stop, meaning it will not hold a 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 SAIJ100AX475-100S Is Used
Variable End-Stop Machining
Dial in the 375-475 mm travel window during tooling setups to accommodate different part lengths without replacing the cylinder.
Product Changeover Lines
Quickly adjust the retract position on packaging conveyors to handle varying box sizes on the same ISO 15552 footprint.
Commissioning Calibration
Fine-tune the end-of-stroke position during machine commissioning to perfect timing and avoid mechanical hard stops.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX475-100S the Right Cylinder?
Choose this adjustable-stroke model over a fixed SAI cylinder when your application requires frequent machine setup or product changeover, letting you dial in the end-stop without adding external stops. If you need less force, stepping down to an 80 mm bore yields 4523 N at 0.9 MPa. Because the 475 mm stroke is long, the 25 mm rod and M20x1.5 thread handle significant side load, but an external guide is recommended for unsupported lengths. For load-holding without live air, select the SAIL or BSAI series instead, as this adjuster is not a lock. To match this ISO 15552 cylinder, specify the 100 mm bore, 475 mm stroke, 100 mm adjustment, PT port thread, and -S magnet.
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 SAIJ100AX475-100S FAQ
It delivers a maximum of 801 kgf at 1.0 MPa.
The rear adjuster screw lets you shorten the 475 mm nominal stroke by up to 100 mm, creating a 375-475 mm usable travel window. It functions as a stop for end-position tuning and does not lock the load without air pressure.
