About the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX300-10S
The AirTAC SAIJ80X300-10-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster. It provides a 2513N push force at 0.5 MPa and uses a PT tapered G3/8 port. The integrated rear stopper screw allows you to fine-tune the retract position, creating a usable travel window of 290-300mm for precise machine setup.
This unit includes a piston magnet for CMSE reed and DMSE electronic sensors. The rod is built from SUS420J2 stainless steel for corrosion resistance. Because the 300mm stroke is long, the M20x1.5 rod thread and 25mm diameter require an external guide to prevent side-load damage. The rear adjuster acts only as a travel stop and does not hold the load without live air pressure.

Where the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX300-10S Is Used
Variable End-Stop Machining
Dial in the 290-300mm travel window during machine setup to accommodate different part lengths without physically remounting the actuator.
Product Changeover Diversion
Fine-tune the retract position on packaging lines to handle varying box sizes quickly using the rear adjustment screw.
Long-Stroke Assembly Press
Utilize the 2513N push force over a 300mm stroke while relying on external guides to manage side loads during component insertion.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX300-10S the Right Cylinder?
Choose this 80mm bore when a 50mm bore yields only 982N push force at 0.5 MPa, but you want to avoid stepping up to a 100mm bore that generates 3927N. The 10mm adjustment range is ideal for product changeover, letting you dial in the exact end position without swapping cylinders or adding external stops. For load-holding without live pressure, select the SAIL or BSAI series instead, as the SAIJ adjuster is not a lock. This model matches ISO 15552 mounting dimensions and supports Basic, FA, LB, TC, FTC, TCM1, and TCM2 mounts.

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 SAIJ80AX300-10S FAQ
The rear adjuster screw acts as a mechanical stop, allowing you to shorten the effective stroke by up to 10mm. This creates a usable travel window of 290-300mm, enabling fine-tuning of the end position at commissioning without swapping the cylinder.
At 0.5 MPa operating pressure, it provides a push force of 2513N and a pull force of 2268N. The maximum push force reaches 4523N at 0.9 MPa.
