About the Airtac SAIJ80 Adjustable Cylinder SAIJ80X140-100S
The AirTAC SAIJ80X140-100-S is a double-acting, single-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It features an 80 mm bore generating 2513 N of push force at 0.5 MPa, alongside a generous 100 mm adjustment range that creates a highly flexible 40-140 mm usable travel window. This wide variability makes it exceptionally practical for prototyping or machinery that processes multiple product sizes on the same line.
Fitted with a PT tapered port and a -S magnet, this unit supports AirTAC CMSE reed and DMSE electronic solid-state sensors in the dual-side extruded barrel grooves. The carbon steel piston rod with its M20x1.5 thread provides robust resistance against side loads, while the reduced SAIJ mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2) omits FB, CA, CB, and CR brackets to streamline your design.

Where the Airtac SAIJ80 Adjustable Cylinder SAIJ80X140-100S Is Used
Product Changeover
Dial in the 40-140 mm travel window rapidly on packaging lines that switch between varying container sizes without changing hardware.
Prototype Setup
Fine-tune the exact end-of-stroke position during machine commissioning to perfect timing and avoid mechanical hard crashes.
Variable End Stops
Use the 100 mm adjustment range to modify the extend distance dynamically for testing different material feed lengths.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80X140-100S the Right Cylinder?
Choose this 80 mm bore when an application demands high thrust—such as 2513 N push at 0.5 MPa—over a widely variable end-position. If your setup requires less force, stepping down to a 63 mm bore yields 1559 N push; if you need substantially more power, a 100 mm bore provides 3927 N. The 100 mm adjustment screw allows precise end-stop tuning during commissioning or product changeover without swapping cylinders or adding external stops. Because the 140 mm nominal stroke is under 300 mm, external side-load guides are less critical, though the M20x1.5 rod still handles standard operational stresses well.
For ISO 15552 replacement matching, ensure you specify the 80 mm bore, 140 mm nominal stroke, 100 mm adjuster, PT port thread, and the -S magnet option. Remember that the rear adjuster functions strictly as a travel stop and does not hold the load without live air; for dead-air load holding, consider an AirTAC SAIL or BSAI cylinder instead.

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 SAIJ80X140-100S FAQ
The rear adjuster acts as a mechanical stop that lets you trim the effective stroke. With a 140 mm nominal stroke and a 100 mm adjustment range, the usable travel window is 40-140 mm. It only sets the travel end and does not lock the load without live air pressure.
At 0.5 MPa operating pressure, the SAIJ80X140-100-S generates 2513 N of push force and 2268 N of pull force. It can achieve up to 4523 N of push force at its maximum 0.9 MPa operating pressure.
