About the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX400-30
The AirTAC SAIJ100X400-30 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster, engineered to fine-tune the end-of-travel position during machine commissioning without adding external stoppers. With a 400mm nominal stroke and a 30mm adjustment range, it provides a usable travel window of 370 to 400mm.
This SKU is configured with a SUS420J2 stainless steel rod (option A) for corrosion resistance and features PT tapered port threads. The extruded aluminum barrel includes sensor grooves on both sides, though this specific unit lacks a magnet for position sensing. The rear adjuster acts purely as a travel stop to set deceleration limits and does not lock or hold the load without continuous live air pressure.

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 SAIJ100AX400-30 Is Used
Product Changeover Tuning
Dial in the 370-400mm travel window during rapid product size transitions on packaging lines without physically swapping the cylinder.
Assembly End-Stop Calibration
Fine-tune the rear stopper screw during machine commissioning to perfect the end-position of critical assembly operations.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX400-30 the Right Cylinder?
The 30mm adjustable end-stop is selected over a fixed-stroke SAI when a product line requires exact end-position tuning during changeovers. Because the 400mm stroke is substantial, an external guide is recommended to prevent side-loading damage to the M20x1.5 rod thread. For applications requiring true load-holding without live air, select the SAIL or BSAI series instead, as the SAIJ adjuster is not a brake.
As a dimensionally interchangeable ISO 15552 cylinder, this model matches standard mounting footprints. It uses the reduced SAIJ mounting set: Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting the FB, CA, CB, and CR variants. Operating speed spans 30 to 800 mm/s, regulated by variable air cushions at both ends.

- ✓ 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 SAIJ100AX400-30 FAQ
The operating speed ranges from 30 to 800 mm/s, controlled by variable air cushions at both ends.
The rear adjuster screw allows you to shorten the effective stroke by up to 30mm, providing a usable travel window of 370 to 400mm. It acts as a travel stop to fine-tune end positions and does not hold the load without live air.
