About the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX55-30
The AirTAC SAIJ100X55-30 is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, allowing you to dial back the nominal 55 mm travel by up to 30 mm. This creates a highly customizable 25-55 mm usable stroke window, perfect for dialing in exact end positions during commissioning. It delivers robust thrust, pushing 3927 N and pulling 3681 N at 0.5 MPa.
This SKU features a SUS420J2 stainless steel rod (material code A) for enhanced corrosion resistance and carries a PT tapered port thread. The extruded aluminum barrel includes sensor grooves on both sides, ready for CMSE reed or DMSE electronic switches if a magnet is added later. The rear screw acts purely as a travel stop to fine-tune deceleration, meaning it will not hold a 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 SAIJ100AX55-30 Is Used
Product Changeovers
Quickly adapt the end-of-stroke position for varying product sizes on a packaging line without changing out the entire actuator.
Machine Setup
Fine-tune the 25-55 mm travel window during initial commissioning to achieve precise mechanical alignment without external shims.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX55-30 the Right Cylinder?
The adjustable 25-55 mm window is ideal for product changeovers on a line, letting you shift the end-stop without physically swapping the cylinder or adding external stops. If your process requires the load to be mechanically locked in place without air pressure, you would need to step away from the SAIJ and look at the SAIL or BSAI locking variants.
For an exact ISO 15552 replacement match, verify the 100 mm bore, 55 mm stroke, 30 mm adjustment range, PT port thread, and the specific mounting subset. SAIJ supports Basic, FA, LB, TC, FTC, TCM1, and TCM2 mounts, deliberately omitting FB, CA, CB, and CR options. Because the stroke is under 300 mm, side-load stress on the 25 mm rod is minimal, though external guides are always recommended for heavy lateral loads.
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 SAIJ100AX55-30 FAQ
At the maximum 1.0 MPa pressure, it can deliver up to 801 kgf.
The rear adjuster screw lets you shorten the 55 mm nominal stroke by up to 30 mm, providing a usable travel window of 25-55 mm. This stopper sets the travel end and works with the air cushion for deceleration, but it does not lock the load without live air.
