About the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX375-40
By turning the external stopper screw, you can trim the effective travel within a 335-375mm window. This allows precise end-position tuning at commissioning without swapping the cylinder or bolting on external stops.
Built with a SUS420J2 stainless steel rod for superior corrosion resistance, this 100mm bore unit features PT tapered G1/2 ports and variable air cushions at both ends. The extruded aluminum barrel includes sensor grooves on both sides for flexible switch mounting. Remember that the rear adjuster acts only as a travel stop to set deceleration, not as a lock to 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 SAIJ100AX375-40 Is Used
Product Size Changeover
Dial in the 335-375mm travel window during format changeovers on packaging lines to accommodate different carton depths instantly.
Machine Setup Tuning
Fine-tune the exact end-stop position during initial commissioning without machining new spacer blocks or replacing the entire actuator.
Variable End Stops
Provide a customizable mechanical stop for automated assembly presses requiring slight positional adjustments between batches.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX375-40 the Right Cylinder?
The adjustable 335-375mm window is ideal for machines handling multiple product sizes, allowing rapid changeover without mechanical modifications. For fixed-position tasks without variation, a standard SAI cylinder is simpler.
Because the 375mm stroke is substantial, the 25mm rod diameter requires an external guide to prevent excessive side-loading and premature seal wear. This SAIJ model uses a reduced mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2) and omits FB, CA, CB, and CR brackets. It is dimensionally interchangeable per ISO 15552. If your application requires holding a load without continuous air pressure, select a SAIL lock or BSAI clamp-lock cylinder instead of relying on the adjuster.
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 SAIJ100AX375-40 FAQ
At the maximum 1.0 MPa pressure, it delivers a peak push force of 801kgf.
The rear adjuster screw allows you to shorten the 375mm nominal stroke by up to 40mm, creating a usable travel window of 335-375mm. This stopper sets the travel end and deceleration point but does not lock or hold the load without live air pressure.
