About the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX300-30
The AirTAC SAIJ100X300-30 is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a nominal 300 mm travel that can be fine-tuned down by up to 30 mm, creating a precise 270-300 mm usable window.
This unit utilizes a SUS420J2 stainless steel rod (option A) for enhanced corrosion resistance and features PT tapered port threads (G1/2). The extruded aluminum barrel includes dual sensor grooves, allowing you to easily mount CMSE reed or DMSE electronic solid-state switches exactly where needed for end-position confirmation.

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 SAIJ100AX300-30 Is Used
Product Size Changeovers
Quickly fine-tune the 270-300 mm retract distance during format changes on packaging lines without replacing hardware.
Machine Setup Calibration
Dial in the precise end-stop during initial commissioning to perfect the timing of automated assembly equipment.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX300-30 the Right Cylinder?
The adjustable 270-300 mm window is ideal for product-size changeovers on a line, allowing you to dial in the exact retract end-position without swapping out the entire cylinder or adding external stops. Note that the rear adjuster acts purely as a travel stop; it will not hold the load without live air pressure. For fail-safe load holding without continuous air, consider an AirTAC SAIL pneumatic lock or a BSAI clamp-lock cylinder.
Because this unit features a 300 mm stroke, the 25 mm rod diameter and M20x1.5 rod thread provide robust support, but an external guide is still recommended to prevent excessive side-loading on the piston. It is dimensionally interchangeable per ISO 15552 and uses a reduced mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2), omitting FB, CA, CB, and CR rear clevis options.
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 SAIJ100AX300-30 FAQ
At the maximum 1.0 MPa pressure, it can deliver up to 801 kgf.
The rear adjuster screw allows you to shorten the effective stroke by up to 30 mm, providing a usable travel window of 270 to 300 mm. This stopper fine-tunes the end position but does not lock the load without live air pressure.
