About the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX750-30
The AirTAC SAIJ100X750-30 is a double-acting, single-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. Delivering 3927 N of push force at 0.5 MPa, it handles heavy loads while allowing on-the-fly end-position calibration.
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.

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.
Heavy Fixture Alignment
Position heavy machining fixtures with 3927 N of push force at 0.5 MPa, relying on the 30 mm adjustment window to perfectly square the part against a hard stop.
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?
Choose this 100 mm bore when your application requires substantial thrust, such as the 3927 N push force at 0.5 MPa, but still needs precise position tuning at commissioning. If your setup demands less force, stepping down to an 80 mm bore yields 2513 N of push force. 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.

- ✓ 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 a 0.5 MPa operating pressure, this double-acting cylinder provides 3927 N of push force and 3681 N of pull force. At 0.7 MPa, the push force increases to 5497 N.
