About the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX450-100
The AirTAC SAIJ100X450-100 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to trim the effective travel within a 350-450 mm window. This built-in adjuster enables fine end-position tuning at commissioning without swapping the cylinder or adding external stops.
The unit is fitted with a SUS420J2 stainless steel rod (material code A) for enhanced corrosion resistance and features a PT tapered G1/2 port. The extruded aluminum barrel includes sensor grooves on both sides for flexible mounting of CMSE reed or DMSE electronic switches. It uses a reduced mounting set of Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting the FB, CA, CB, and CR options found on some other 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 SAIJ100AX450-100 Is Used
Product Changeover
Dial in the 350-450 mm travel window during product size transitions on a packaging line without physically swapping cylinders.
Machine Setup
Fine-tune the retract end-position precisely at commissioning to avoid adding external mechanical stops to the machine frame.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX450-100 the Right Cylinder?
The 100 mm adjustment range is perfect for product-size changeovers on a line.
When replacing an ISO 15552 cylinder, match the 100 mm bore, 450 mm stroke, 100 mm adjustment, PT G1/2 port, and your required mounting style. Because the nominal stroke is 450 mm, an external guide is recommended to handle side loads and prevent rod deflection. Remember that the rear adjuster acts only as a travel stop and does not hold the load without live air; for position holding without pressure, consider an external rod lock or the SAIL and BSAI series.
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 SAIJ100AX450-100 FAQ
At the maximum 1.0 MPa pressure, it delivers up to 801 kgf.
The rear external adjuster screw acts as a stopper that can shorten the 450 mm nominal stroke by up to 100 mm, creating a usable travel window of 350-450 mm. It sets the travel end and provides deceleration, but it is not a lock and will not hold the load without live air pressure.
