About the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX225-100
The AirTAC SAIJ80X225-100 is a double-acting, double-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. By turning the rear stopper screw, you can trim the forward travel back by up to 100mm, creating a usable working window of 125 to 225mm without changing the physical cylinder length.
This adjuster functions purely as a mechanical end-stop to fine-tune the retraction position during commissioning or product changeovers; it does not lock the load without live air. The extruded aluminum barrel includes sensor grooves on both sides, ready for CMSE reed or DMSE electronic switches if a magnet is specified later. It supports a speed range of 30-800mm/s and uses a PT G3/8 port.

Theoretical Output Force (Ø80mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 2268 N | 2268 N |
| 0.7 MPa | 3175 N | — |
| Max (@1.0 MPa) | 463 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 SAIJ80 Adjustable Cylinder SAIJ80BX225-100 Is Used
Variable Product Changeover
Quickly dial the stroke back from 225mm down to 125mm when a packaging line switches to a smaller carton size, using the rear screw to set the new end position without changing hardware.
Machine Setup Calibration
Fine-tune the exact end-stop during initial commissioning to achieve perfect pressing force, eliminating the need to add external shims or spacers to the fixture.
Adjustable Ejection Stroke
Control the ejection distance of parts from a machine bed, accommodating different part widths on the fly by adjusting the rear stopper within the 100mm window.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX225-100 the Right Cylinder?
The 100mm adjustment range is ideal for machines processing varying product sizes, allowing operators to dial in the exact end-stop on the fly instead of swapping out a fixed-stroke SAI cylinder. Remember that the rear adjuster only sets the travel limit and decelerates the load via the variable air cushion—it will not hold a load in place without continuous air pressure. For dead-load holding, consider an external rod lock or the SAIL pneumatic lock series.
Because the 225mm stroke is relatively long, ensure adequate external guidance to prevent excessive side-loading on the M20x1.5 rod. This unit is dimensionally interchangeable per ISO 15552 and uses the standard SAIJ mounting subset: Basic, FA, LB, TC, FTC, TCM1, and TCM2 (omitting FB, CA, CB, and CR). It features a PT tapered port thread and a SUS304 stainless steel rod for enhanced corrosion resistance.

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 SAIJ80 Adjustable Cylinder SAIJ80BX225-100 FAQ
At the maximum operating pressure of 1.0 MPa, it can deliver up to 513 kgf.
The rear adjuster screw acts as a mechanical stop that lets you shorten the effective stroke by up to 100mm. This creates a usable travel window of 125 to 225mm, allowing you to set the exact end position during setup without replacing the cylinder.
