About the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX270-10
The AirTAC SAIJ100X270-10 is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster. It provides a 260-270mm usable travel window, allowing you to trim the effective stroke by up to 10mm during commissioning.
The rear screw acts purely as a mechanical stop to fine-tune the retract end position without adding external stops. It does not lock the load without live air. This extruded aluminum barrel includes sensor grooves on both sides, and its mounting options cover Basic, FA, LB, TC, FTC, TCM1, and TCM2.

Specifications follow the official AirTAC SAI series datasheet and ISO 15552 dimensions. Confirm against the product label before installation. Port options: G (BSPP) / NPT.
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 SAIJ100BX270-10 Is Used
Machine Setup Changeover
Dial in the 260-270mm travel window during product family changeovers to perfectly strike varying workpieces without swapping out the entire actuator.
Variable End-Stop Positioning
Use the 10mm rear adjustment to fine-tune where a heavy pallet stops on a conveyor line, accommodating minor mechanical drift on the fly.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX270-10 the Right Cylinder?
If your application needs less force, stepping down to an 80mm bore yields 3518N at 0.7MPa. Because the 270mm stroke exceeds 300mm? No, but at 270mm with a heavy load, ensuring proper external guiding is still recommended to manage side loads.
For an exact ISO 15552 replacement, match the 100mm bore, 270mm stroke, 10mm adjustment, PT port threads, and SUS304 rod material. Note that this cylinder uses live air to maintain position; the rear adjuster only sets the travel limit. For load-holding without air pressure, consider an AirTAC SAIL or BSAI cylinder.
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 SAIJ100BX270-10 FAQ
At the maximum 1.0MPa pressure, it achieves 801kgf.
The rear adjuster screw lets you shorten the nominal 270mm stroke by up to 10mm, creating a 260-270mm travel window. It functions as a mechanical stop for end-position tuning and does not lock the load.
