About the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX750-30
The AirTAC SAIJ100X750-30 is a double-acting, double-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It provides a nominal 750 mm stroke that can be fine-tuned backward by up to 30 mm, creating a precise 720-750 mm usable travel window.
This unit features a SUS304 stainless steel rod for superior corrosion resistance and utilizes a PT tapered port thread. The extruded aluminum barrel includes dual sensor grooves, though this specific SKU is configured without a magnet. The rear adjuster acts purely as a mechanical stop to set the travel end and does not lock or hold the 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 SAIJ100BX750-30 Is Used
Product Changeover
Dial in the 720-750 mm travel window during format size changes on a packaging line, using the rear screw to set new end positions instantly without mechanical rebuilds.
Variable End-Stop Actuation
Actuate large automated gates or presses where the exact retraction point varies by batch, tuning the stroke directly at the machine rather than in CAD.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX750-30 the Right Cylinder?
Conversely, heavier payloads might require the 125 mm bore at 6136 N. The adjustable stroke is ideal for product changeovers on a line, allowing you to shift the end-stop by up to 30 mm without swapping the cylinder or adding external stops.
Because this cylinder features a 750 mm stroke, the relatively long unsupported travel necessitates an external guide to prevent excessive side-loading on the SUS304 rod, despite its robust M20x1.5 thread. For load-holding without live air pressure, a standard SAIJ is insufficient; you should explore an AirTAC SAIL or BSAI cylinder instead. This model is dimensionally interchangeable with ISO 15552 cylinders and supports Basic, FA, LB, TC, FTC, TCM1, and TCM2 mounts.
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 SAIJ100BX750-30 FAQ
It features a rear mechanical stopper that allows you to trim the effective stroke by up to 30 mm. This provides a usable travel window of 720-750 mm, letting you fine-tune the end position at commissioning without changing the cylinder.
At 0.7 MPa, the push force increases to 5497 N.
