About the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX450-100S
The AirTAC SAIJ100X450-100-S is a double-acting, double-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It provides a nominal 450 mm stroke that can be dialed back by up to 100 mm, creating a precise 350-450 mm usable travel window. This allows you to fine-tune the retract end position at commissioning without swapping the cylinder or adding external stops. The extruded aluminum barrel features sensor grooves on both sides.
This specific SKU includes a SUS420J2 stainless steel rod (code A) for enhanced corrosion resistance and ships with a magnet (-S) for use with CMSE reed and DMSE electronic sensors. The rear adjuster acts strictly as a travel stop and does not hold the load without live air.

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 SAIJ100AX450-100S Is Used
Variable End-Stop Positioning
Dial in the retract distance from 350 to 450 mm during machine setup to accommodate different product sizes without physically changing the cylinder.
Product Changeover Diverters
Quickly adjust the stroke window on packaging lines when switching between box sizes, relying on the SUS420J2 rod for durability in varied environments.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX450-100S the Right Cylinder?
Choose this 100 mm bore cylinder when an application requires substantial thrust, such as 3927 N at 0.5 MPa, but demands a variable end-stop for product changeovers. The adjustable stroke is ideal for dialing in exact retract distances on the fly, whereas a fixed SAI cylinder is better suited for static, unchanging strokes. For load-holding without continuous air pressure, you must use an external rod lock or look to the SAIL or BSAI series, as the SAIJ adjuster is not a locking mechanism.
Because this unit features a 450 mm stroke, the 25 mm rod and M20x1.5 rod thread will experience leverage forces during operation; an external guide should be used to prevent excessive side-loading. This cylinder is dimensionally interchangeable per ISO 15552 and uses a reduced mounting set of Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR. It uses PT tapered port threads and operates at speeds of 30-800 mm/s.

- ✓ 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 SAIJ100AX450-100S FAQ
At 0.7 MPa, the push force increases to 5497 N.
The rear adjuster screw allows you to shorten the effective stroke by up to 100 mm. This creates a usable travel window of 350-450 mm, letting you set the exact retract end position without adding external stops.
