About the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX40-10
The AirTAC SAIJ100X40-10 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to fine-tune the end position during commissioning. With a nominal 40 mm stroke and a 10 mm adjustment screw, it provides a usable travel window of 30 to 40 mm to perfectly dial in your machine's end-stop without adding external shims.
This unit is configured with a SUS420J2 stainless steel rod (code A) for enhanced corrosion resistance and utilizes PT tapered port threads. The extruded aluminum barrel includes sensor grooves on both sides for flexible switch mounting. It supports a speed range of 30-800 mm/s and uses the standard SAIJ mounting set (Basic, FA, LB, TC, FTC, TCM1, 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 SAIJ100AX40-10 Is Used
Machine Setup & Changeover
Dial in the 30 to 40 mm travel window during product changeovers without swapping out the physical cylinder or adding external shims.
Variable End-Stop Tuning
Use the rear adjusting screw to fine-tune the retract end-position by up to 10 mm, perfect for precision pressing and clamping operations.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX40-10 the Right Cylinder?
Choose this 100 mm bore model when your application requires high thrust—delivering 3927 N at 0.5 MPa—and you need precise end-position tuning within a 30 to 40 mm travel window. If your force requirements are lower, stepping down to an 80 mm bore yields 2513 N at 0.5 MPa, whereas stepping up to a 125 mm bore provides 6136 N. The adjustable stroke is selected over a fixed SAI cylinder when machine setup requires variable end-stops or product changeovers without physically swapping the actuator.
When replacing an ISO 15552 cylinder, match the 100 mm bore, 40 mm stroke, 10 mm adjustment, PT ports, and your required mounting bracket. Note that the rear adjuster acts only as a travel stop to set deceleration; it does not hold the load without live air. For load-holding without continuous pressure, consider the SAIL or BSAI series. Because the stroke is under 300 mm, side-load concerns are minimal, but long unsupported loads still require an external guide.
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 SAIJ100AX40-10 FAQ
At 0.9 MPa, the push force increases to 7068 N.
The rear adjuster screw allows you to shorten the effective travel from the nominal 40 mm stroke down to 30 mm. This creates a 30 to 40 mm adjustable window, letting you set the exact retract end-position during commissioning without changing the cylinder.
