About the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX90-30
The AirTAC SAIJ100X90-30 is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster. The built-in adjustment screw allows you to trim the 90mm nominal stroke back by up to 30mm, creating a precise 60-90mm usable travel window for exact end-position tuning without swapping hardware.
This variant features a SUS420J2 stainless steel rod (code A) for enhanced corrosion resistance over standard carbon steel. It uses PT tapered port threads (G1/2) and includes adjustable air cushions at both ends to absorb kinetic energy. The extruded aluminum barrel offers sensor grooves on both sides, though this specific SKU omits the magnet, so external CMSE or DMSE switches cannot be used without modification.

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 SAIJ100AX90-30 Is Used
Precision End-Stop Tuning
Dial in the exact 60-90mm travel distance during machine commissioning to achieve precise positioning without machining external stopper blocks.
Product Size Changeover
Quickly adapt the cylinder's effective stroke on the fly when a production line switches to a different sized package or component.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX90-30 the Right Cylinder?
Conversely, if you need heavier thrust, a 125mm bore provides 6136N. The adjustable rear stopper is ideal for fine-tuning the 60-90mm travel window during machine commissioning, entirely removing the need to bolt on external stops or change cylinders.
When replacing an ISO 15552 cylinder, match the 100mm bore, 90mm stroke, 30mm adjustment range, PT port threads, and the desired mounting accessory. SAIJ supports a reduced mounting set including Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR brackets. Because the 90mm stroke is relatively short, side-loading is less severe than in long-stroke units, but the 25mm rod diameter and M20x1.5 rod thread still handle substantial side loads. Remember, the rear adjuster acts only as a travel stop; it will not hold a load without live air. For true pneumatic locking, consider the SAIL or 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 SAIJ100AX90-30 FAQ
A rear external adjusting screw acts as a mechanical stopper, allowing you to shorten the 90mm nominal stroke by up to 30mm. This creates a usable travel window of 60-90mm, which can be fine-tuned during setup without replacing the cylinder.
