About the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX230-50S
The AirTAC SAIJ80X230-50-S is a double-acting, single-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It delivers a substantial 3518N push force at 0.7MPa, placing it in a heavy-duty force class for demanding pneumatic tasks. The integrated -S magnet enables position sensing across both sensor grooves using AirTAC CMSE reed or DMSE electronic solid-state switches.
This specific SKU features a 230mm nominal stroke that can be dialed back by up to 50mm, yielding a highly flexible 180-230mm usable travel window. The SUS420J2 stainless steel rod (code A) provides enhanced corrosion resistance compared to standard carbon steel. By turning the external rear stopper, you can fine-tune the retract end position during commissioning or product changeover without swapping the entire cylinder or adding external physical stops.

Where the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX230-50S Is Used
Variable End-Stop Tuning
Dial in the retract position within the 180-230mm window during machine commissioning to perfectly set material push-off distances without hardware changes.
Product Size Changeover
Quickly adapt a packaging line for different carton lengths by adjusting the rear stopper screw up to 50mm, minimizing downtime between production runs.
Heavy-Duty Positioning
Leverage the 3518N push force at 0.7MPa to shift heavy pallets or fixtures into place, using the fine adjustment to perfect the final resting position.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX230-50S the Right Cylinder?
Select this 80mm bore adjustable-stroke model when your fixture or machine requires variable end-position tuning within a 180-230mm travel window. If you need less force, the 63mm bore neighbor provides 2182N push at 0.7MPa; stepping up to the 100mm bore yields 5497N for heavier loads. Because this is a 230mm stroke, ensure your mounting arrangement handles side loads—while the 25mm rod and M20x1.5 thread provide robustness, long unsupported strokes still require an external guide to prevent rod binding.
Choose this SAIJ adjustable variant over a fixed SAI cylinder when your setup demands frequent end-stop adjustments for varying product sizes. Note that the rear adjuster acts strictly as a travel stop and the air cushions handle deceleration; neither will hold the load without live air pressure. For fail-safe load holding, select a related type like the SAIL (air-released lock) or BSAI (clamp-lock) cylinder instead. This configuration uses PT tapered ports and supports the reduced SAIJ mounting set: Basic, FA, LB, TC, FTC, TCM1, and TCM2 (omitting FB, CA, CB, and CR).

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 SAIJ80AX230-50S FAQ
At a standard 0.7MPa operating pressure, this 80mm bore cylinder generates 3518N of push force and 2268N of pull force. It can deliver up to 4523N push force at its maximum 0.9MPa pressure.
The rear external stopper screw allows you to shorten the effective travel from the 230mm nominal stroke down to as little as 180mm. This provides a 50mm adjustment window for fine-tuning the end position without replacing the cylinder.
