About the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX240-100S
The AirTAC SAIJ80X240-100-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, providing a highly flexible usable travel window of 140-240 mm. It delivers substantial thrust, pushing with 2513 N and pulling with 2268 N at 0.5 MPa, making it well suited for heavy positioning tasks. The piston rod is constructed from SUS420J2 stainless steel for enhanced durability against moisture, and the integrated magnet (-S) supports precise end-of-stroke detection via CMSE reed or DMSE electronic sensors.
This model uses a PT tapered port thread and relies on a 25 mm rod with an M20x1.5 thread to handle demanding side loads. The external rear adjusting screw acts purely as a travel stop to fine-tune the retract position during commissioning or product changeovers without adding external stops. It is important to note that this adjuster and the variable air cushions at both ends only decelerate the load; they do not hold the position without live air pressure.

Where the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX240-100S Is Used
Variable Product Changeover
Dial in the exact retract stop for different material lengths on a single machine bed without physically swapping out the actuator.
Adjustable Diverter Stroke
Fine-tune the pusher travel window between 140 and 240 mm to accommodate varying package sizes on a sorting line.
Commissioning End-Tuning
Use the rear stopper to precisely set the home position during machine setup, avoiding the need for external shims.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX240-100S the Right Cylinder?
Select this 80 mm bore cylinder when your application requires a 140-240 mm stroke range but demands higher force than a 63 mm bore can provide (which offers 1559 N push at 0.5 MPa). The 100 mm adjustment range is ideal for machines processing varying product sizes, allowing rapid end-stop tuning without swapping cylinders. For load-holding requirements without live air, consider the SAIL or BSAI series instead, as the SAIJ adjuster is strictly a stop.
When replacing an ISO 15552 cylinder, match the 80 mm bore, 240 mm nominal stroke, 100 mm adjustment, PT port thread, and the -S magnet requirement. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2 options, omitting FB, CA, CB, and CR. Because the stroke is 240 mm, ensure adequate external guiding to prevent excessive side-loading on the M20x1.5 rod.
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 SAIJ80AX240-100S FAQ
At an operating pressure of 0.5 MPa, this 80 mm bore cylinder provides a push force of 2513 N and a pull force of 2268 N. At the maximum rated pressure of 1.0 MPa, the push force reaches 513 kgf.
The rear adjuster screw allows you to shorten the effective stroke by up to 100 mm from the nominal 240 mm, creating a usable travel window of 140-240 mm. The adjuster acts as a mechanical stop to tune the end position and does not lock the load.
