About the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX90-40
The AirTAC SAIJ100X90-40 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to trim the effective travel. With a nominal 90 mm stroke and a 40 mm adjustment range, you get a usable travel window of 50-90 mm. This enables fine end-position tuning at commissioning or during product changeover without swapping the cylinder or adding external stops.
This SKU is built with a SUS420J2 stainless steel rod (option A) for superior corrosion resistance and uses PT tapered port threads (G1/2). The extruded aluminum barrel includes sensor grooves on both sides. Note that the rear adjuster acts purely as a travel stop to set the end position; it does not hold the load without live air pressure. For load-holding requirements, consider the SAIL or BSAI series.

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 SAIJ100AX90-40 Is Used
Machine Changeover
Dial in the exact end-stop from 50 to 90 mm during product size changeovers without replacing the cylinder or adding external shims.
End-Position Tuning
Fine-tune the retract position at commissioning to absorb mechanical tolerances and achieve precise alignment in assembly lines.
Variable Stroke Pressing
Adapt the travel window on the fly for pressing or clamping operations that require different material thicknesses.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX90-40 the Right Cylinder?
If you need less force, stepping down to an 80 mm bore yields 2513 N at the same pressure. The 40 mm adjustment range is ideal for variable end stops on machines that process different product sizes, offering a 50-90 mm travel window. When replacing an ISO 15552 cylinder, match the 100 mm bore, 90 mm stroke, 40 mm adjustment, G1/2 PT port, and mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2). Because this SKU lacks the -S magnet option, it cannot host CMSE or DMSE sensors without modification.
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 SAIJ100AX90-40 FAQ
At 0.7 MPa, the push force increases to 5497 N.
The rear adjuster screw acts as a mechanical stop, allowing you to shorten the 90 mm nominal stroke by up to 40 mm. This creates a usable travel window of 50-90 mm for fine-tuning without moving the cylinder mounts.
