About the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX300-100S
The AirTAC SAIJ100X300-100-S is a double-acting, double-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. The built-in magnet supports CMSE reed and DMSE electronic sensors for precise position detection.
This specific SKU provides a 200-300 mm usable travel window, allowing you to dial back the nominal 300 mm stroke by up to 100 mm. It features a G1/2 port and variable air cushions at both ends to manage impact. The external rear screw acts purely as a travel stop for commissioning fine-tuning, 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 SAIJ100AX300-100S Is Used
Variable End-Stop Machining
Fine-tune the 200-300 mm travel window during machine setup to accommodate different part lengths without adding external stopper blocks.
Product Changeover Lines
Quickly adjust the retract end position on packaging or conveying equipment to handle varying box sizes on the fly.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX300-100S the Right Cylinder?
Choose this adjustable-stroke model over a fixed SAI when your application requires variable end positions or frequent product-size changeovers without swapping cylinders. Because this unit features a 300 mm stroke, the 25 mm rod and M20x1.5 thread provide substantial side-load capacity, but an external guide is still recommended for heavy unsupported loads.
To match this ISO 15552 dimensionally interchangeable cylinder, specify a 100 mm bore, 300 mm stroke, 100 mm adjustment, PT tapered G1/2 port, and an -S magnet. It uses a reduced mounting set of Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR. For load-holding without live air, consider the SAIL or BSAI series instead, as the rear adjuster here is a stop, not a lock.
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 SAIJ100AX300-100S FAQ
If you operate at 0.7 MPa, the push force increases to 5497 N.
The rear adjuster screw lets you shorten the effective travel from the nominal 300 mm down to 200 mm. This stopper only sets the end position; it does not lock or hold the load without continuous air pressure.
