About the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX900-100S
The AirTAC SAIJ100X900-100-S is a double-acting, double-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It features a 900 mm nominal stroke that can be dialed back by up to 100 mm, providing an exact 800-900 mm usable travel window for fine-tuning end positions during commissioning.
This variant includes a SUS420J2 stainless steel rod (code A) for enhanced corrosion resistance and a built-in magnet (-S) for use with AirTAC CMSE reed and DMSE electronic sensors. The rear screw acts purely as a travel stop to decelerate the load alongside the standard air cushions, but it does not hold the load without live air pressure. Mounting options include Basic, FA, LB, TC, FTC, TCM1, and TCM2.

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 SAIJ100AX900-100S Is Used
Variable End-Stop Tuning
Dial in the exact 800-900 mm end position during machine commissioning to accommodate different product lengths without physically swapping cylinders.
Product Size Changeover
Quickly adjust the stroke window on packaging lines when switching between different package sizes, minimizing downtime and avoiding external mechanical stops.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX900-100S the Right Cylinder?
The adjustable 800-900 mm window is ideal for product changeovers, allowing you to shift the end-stop without swapping the cylinder or adding external stops. For load-holding without continuous air pressure, integrate an external rod lock or pilot-operated check valve, as the adjuster is not a brake.
Because the 900 mm stroke is long, an external guide is recommended to prevent excessive side-loading on the M20x1.5 rod thread. When specifying a replacement, match the 100 mm bore, 900 mm stroke, 100 mm adjustment, PT tapered port thread, and the -S magnet requirement to ensure full ISO 15552 dimensional interchangeability.
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 SAIJ100AX900-100S FAQ
At 0.9 MPa, the push force increases to 7068 N.
The rear adjuster screw allows you to shorten the effective stroke by up to 100 mm from the 900 mm nominal length, creating an 800-900 mm adjustable travel window. It functions as a mechanical stop to set the end position and is not a lock.
