About the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX475-75S
The AirTAC SAIJ100X475-75-S is a double-acting, double-rod ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. With a nominal stroke of 475 mm and a 75 mm adjustment range, it provides a usable travel window of 400 to 475 mm. This allows you to dial in the exact retract position during commissioning without swapping out the unit.
This specific SKU includes a magnet for electronic DMSE solid-state and reed CMSE position sensing, fitting into the standard sensor grooves machined into both sides of the extruded aluminum barrel. The rod is constructed from SUS420J2 stainless steel (code A) for enhanced corrosion resistance, and the fluid ports utilize a PT tapered thread standard. It uses a reduced mounting interface subset of Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR brackets.

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 SAIJ100AX475-75S Is Used
Machine Changeover
Quickly fine-tune the 400-475 mm retract end-position during product size or format changes on a packaging line without replacing the cylinder.
Variable Diverting
Adjust the stroke window on a diverter arm to handle varying package lengths on a shared conveyor system.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX475-75S the Right Cylinder?
The 75 mm rear adjuster is chosen when you need variable end-stops for product changeovers on a shared line, providing a 400-475 mm travel window without adding external mechanical stops. For load-holding without live air pressure, note that this cylinder's adjuster acts only as a travel stop, not a lock; you would need to specify a SAIL or BSAI series cylinder instead.
When replacing an ISO 15552 cylinder, match the 100 mm bore, 475 mm nominal stroke, 75 mm adjustment, PT port threads, and the -S magnet requirement. Because the 475 mm stroke is relatively long, the 25 mm rod and M20x1.5 thread provide rigidity, but an external guide is still recommended to prevent excessive side-loading on the piston rod.
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 SAIJ100AX475-75S FAQ
At the maximum 1.0 MPa pressure, it delivers up to 801 kgf.
The rear adjuster screw acts as a mechanical stop, allowing you to shorten the effective stroke from 475 mm down to 400 mm. It only sets the travel end and does not lock or hold the load without live air pressure.
