About the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX475-50S
The AirTAC SAIJ100X475-50-S is a double-acting, double-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It provides a 425-475 mm usable travel window, allowing you to dial back the 475 mm nominal stroke by up to 50 mm during commissioning without adding external stops.
This variant features a SUS420J2 stainless steel rod for improved corrosion resistance and includes a magnet for CMSE reed and DMSE electronic sensors. The extruded aluminum barrel carries sensor grooves on both sides. It uses a G1/2 port and M20x1.5 rod thread, while the rear adjustment screw acts purely as a travel stop to set end positions 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 SAIJ100AX475-50S Is Used
Machine Setup & Changeover
Fine-tune the 425-475 mm travel window during machine commissioning to set exact retract positions without swapping out the entire cylinder.
Product-Size Line Adjustments
Quickly adapt automated lines to new product sizes by adjusting the retract stroke up to 50 mm, avoiding the need to bolt on external mechanical stops.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX475-50S the Right Cylinder?
Choose the SAIJ adjustable-stroke design over a fixed SAI cylinder when you need to fine-tune the retract end at product changeover. To match this ISO 15552 replacement exactly, specify the 100 mm bore, 475 mm stroke, 50 mm adjustment, PT port thread, Basic/FA/LB/TC/FTC/TCM1/TCM2 mounting, and the -S magnet.
Because the 475 mm stroke is long, the 25 mm rod and M20x1.5 thread still require an external guide to prevent excessive side-loading damage. Remember that the rear adjuster and air cushions only decelerate the travel end; they do not lock the load. For position holding without live air, use an external rod lock, a pilot-operated check valve, or an AirTAC SAIL or BSAI cylinder.
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 SAIJ100AX475-50S FAQ
The rear adjuster screw lets you shorten the 475 mm nominal stroke by up to 50 mm, creating a 425-475 mm usable travel window. The adjuster acts as a travel stop to fine-tune the end position and does not hold the load without live air pressure.
The maximum thrust is 801 kgf at 1.0 MPa.
