About the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX185-75
The AirTAC SAIJ80X185-75 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that trims the nominal 185 mm stroke by up to 75 mm, creating a flexible 110-185 mm usable travel window for precise commissioning. It delivers 2513 N of pull force at 0.5 MPa and reaches a maximum of 513 kgf at 1.0 MPa.
This variant is configured with a SUS420J2 stainless steel rod (code A) for superior corrosion resistance and uses PT tapered port threads. The extruded aluminum barrel includes dual-side sensor grooves, while the mounting set covers Basic, FA, LB, TC, FTC, TCM1, and TCM2, deliberately omitting FB, CA, CB, and CR options.

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 SAIJ80AX185-75 Is Used
Machine Changeover
Dial in the 110-185 mm travel window during product size transitions without physically swapping out the cylinder.
Variable End-Stop Positioning
Set precise retract endpoints on the fly for sorting or diverting packages of varying dimensions.
Assembly Line Calibration
Fine-tune the rear stopper during commissioning to perfect pressing or clamping forces on the production floor.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX185-75 the Right Cylinder?
Choose this 80 mm bore when a 63 mm cylinder (providing 1402 N pull at 0.5 MPa) lacks the thrust to move your load, but a 100 mm bore (3681 N pull) would be excessive. The 75 mm adjustment range is ideal for product-size changeovers on a line, allowing you to dial in the exact end-stop without swapping the cylinder or adding external stops.
For a direct ISO 15552 dimensional replacement, match the 80 mm bore, 185 mm stroke, 75 mm adjustment, PT ports, and the specific mounting accessory. Note that the rear adjuster acts only as a travel stop; it does not hold the load without live air. For fail-safe load holding, consider an external rod lock or the AirTAC SAIL or BSAI series.
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 SAIJ80 Adjustable Cylinder SAIJ80AX185-75 FAQ
At the maximum operating pressure of 1.0 MPa, it delivers a peak thrust of 513 kgf.
The rear adjuster screw acts as a mechanical stop that shortens the effective travel from the 185 mm nominal stroke down to as little as 110 mm. It only sets the end position; it does not lock the load without continuous air pressure.
