About the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX40-40
Because the 40mm nominal stroke is paired with a 40mm adjustment code, you can dial the effective travel all the way down to a 0-40mm window. This allows precise end-position tuning at commissioning without swapping the cylinder or adding external stops.
This SKU features a SUS304 stainless steel rod for superior corrosion resistance and uses a PT tapered port thread. The extruded aluminum barrel includes sensor grooves on both sides, and the rod end utilizes an M20x1.5 thread. The rear adjuster acts purely as a travel stop to set the retract end position, so it 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 SAIJ100BX40-40 Is Used
Product Changeovers
Dial in the 0-40mm travel window during format changes to accommodate different package heights without swapping tooling.
End-Stop Tuning
Fine-tune the retract position during machine commissioning to prevent tooling crashes and ensure precise mechanical alignment.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX40-40 the Right Cylinder?
The adjustable stroke is ideal for product-size changeovers on a line, letting you set variable end-stops on the fly instead of machining fixed spacers. When matching this for an ISO 15552 replacement, verify the 100mm bore, 40mm stroke, 40mm adjustment range, PT port, and mounting style.
Although the 40mm stroke is short, the robust 25mm rod and M20x1.5 thread handle high side loads well. Remember that the rear adjuster is a stop, not a lock; for load-holding without live air, consider an AirTAC SAIL or BSAI cylinder. Mounting options include Basic, FA, LB, TC, FTC, TCM1, and TCM2.
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 SAIJ100BX40-40 FAQ
The rear adjuster screw lets you mechanically shorten the effective stroke anywhere within a 0-40mm window from the nominal 40mm stroke. This allows you to set the exact retract end position during setup without adding external stops.
