About the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX230-75S
The AirTAC SAIJ80X230-75-S is a double-acting, single-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It delivers a robust 2513N push force at 0.5MPa, making it ideal for heavy-duty positioning. The integrated -S magnet enables precise tracking via AirTAC CMSE reed and DMSE electronic sensors housed in the dual-side barrel grooves. Featuring a SUS420J2 stainless steel rod and PT tapered ports, it handles demanding environments with ease.
This model features a 230mm nominal stroke that can be dialed back by up to 75mm, creating a flexible 155-230mm usable travel window. This wide adjustment range allows operators to fine-tune the retract end-position during commissioning or product changeovers without swapping the cylinder. The rear screw acts purely as a travel stop to set the deceleration point alongside the standard air cushions; it is not a lock and will not hold the load without live air pressure.

Where the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX230-75S Is Used
Product Changeover
Dial in the 155-230mm travel window rapidly on packaging lines when switching to different container sizes, eliminating the need to physically swap out cylinders.
Machine Setup
Fine-tune the retract end-position during initial commissioning to achieve perfect alignment, using the rear stopper rather than adding external shims.
Variable End Stops
Adjust the stroke dynamically on automated assembly stations to accommodate multiple part heights within the same work cell.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX230-75S the Right Cylinder?
Selecting this 80mm bore cylinder makes sense when your application requires substantial force—such as the 2513N push or 2268N pull at 0.5MPa—but demands variable end-stops. If your setup only needs fixed travel, a standard SAI cylinder simplifies the build. For lighter loads, stepping down to a 63mm bore yields 1559N push force, whereas moving up to a 100mm bore provides 3927N. Because the stroke is 230mm, ensure the M20x1.5 rod thread and 25mm rod diameter are adequately supported by an external guide to prevent excessive side-loading.
When specifying an ISO 15552 replacement, match the 80mm bore, 230mm stroke, 75mm adjustment range, PT port threads, and the -S magnet requirement. The SAIJ series supports a reduced mounting set including Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR brackets. If your process requires true load-holding without continuous air pressure, consider the SAIL pneumatic lock or BSAI clamp-lock variants instead of relying on the adjuster.

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 SAIJ80AX230-75S FAQ
At 0.5MPa operating pressure, this 80mm bore cylinder provides 2513N of push force and 2268N of pull force. At 0.7MPa, the push force increases to 3518N.
The rear adjuster screw allows you to shorten the effective travel from the 230mm nominal stroke by up to 75mm, providing a usable window of 155-230mm. The screw functions as a mechanical stop to define the end position and does not lock the load without air pressure.
