About the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX700-30S
The AirTAC SAIJ100X700-30-S is a double-acting, double-rod ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a 670 to 700 mm usable travel window, allowing you to dial back the end position by up to 30 mm during commissioning without adding external stops.
This 100 mm bore unit includes a magnet for CMSE reed and DMSE electronic sensors, fitting neatly into the dual-side sensor grooves of the extruded aluminum barrel. The rear adjuster functions purely as a travel stop to set deceleration, not as a load-holding lock, meaning live air pressure is always required to maintain position.

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 SAIJ100BX700-30S Is Used
Variable End-Stop Machining
Fine-tune the 670-700 mm travel window on the fly to accommodate varying part lengths during machining operations without swapping cylinders.
Product Changeover Diverter
Adjust the rear stopper by up to 30 mm to quickly reposition a conveyor diverter arm when switching between different package sizes.
Machine Setup Commissioning
Dial in the exact end position during initial machine commissioning to avoid mechanical collisions and ensure precise timing.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX700-30S the Right Cylinder?
Choose this adjustable-stroke model over a fixed SAI when your machine setup requires variable end-stops or product-size changeovers on the fly. If you need higher clamping force, stepping up to the 125 mm bore yields 6136 N at 0.5 MPa; if less force is acceptable, the 80 mm bore provides 2513 N. To replace this ISO 15552 cylinder exactly, match the 100 mm bore, 700 mm stroke, 30 mm adjustment, PT port, SUS304 rod, and -S magnet.
Because the 700 mm stroke is substantial, the 25 mm rod diameter and M20x1.5 rod thread will carry moderate side loads, but an external guide is recommended for heavy unsupported loads. For applications requiring true load-holding without live air pressure, consider the SAIL or BSAI series instead of relying on the adjuster.
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 SAIJ100BX700-30S FAQ
The rear adjuster screw allows you to shorten the effective stroke by up to 30 mm, creating a 670 to 700 mm usable travel window. It acts as a mechanical stop to tune the end position and does not hold the load without live air pressure.
