About the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX400-30S
The AirTAC SAIJ80X400-30-S is a double-acting, single-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It delivers a robust 3518N push force at 0.7 MPa, utilizing a 25mm piston rod and G3/8 port. The built-in rear stopper allows you to fine-tune the effective travel down from the 400mm nominal stroke, providing a usable adjustment window of 370-400mm without requiring external stops.
This variant includes an -S magnet for position sensing alongside a SUS420J2 stainless steel rod (code A) for improved corrosion resistance. Because the stroke extends to 400mm, the 25mm rod and M20x1.5 rod thread handle substantial loads, but an external guide is recommended to prevent excessive side-loading on the extended rod.

Where the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX400-30S Is Used
Variable End-Stop Tuning
Dial in the exact retraction point within the 370-400mm window during commissioning to perfectly seat heavy components without repositioning physical hard stops.
Product Size Changeover
Quickly adapt a packaging line for different carton lengths by adjusting the rear screw up to 30mm, avoiding cylinder removal or mechanical modifications.
Heavy Material Handling
Leverage the 2513N pull force at 0.5 MPa to push or pull substantial loads, using the adjustable end-position to compensate for mechanical wear over time.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX400-30S the Right Cylinder?
Choose this 80mm bore when a 63mm cylinder falls short of the required thrust; a 63mm SAIJ provides 2182N push at 0.7 MPa, whereas this 80mm unit yields 3518N. The adjustable stroke is ideal for machine setups requiring variable end-stops during product changeovers, eliminating the need to physically swap cylinders for minor length tweaks. If your application requires the load to be held without continuous live air pressure, note that the rear adjuster functions strictly as a travel stop and not a brake—consider an AirTAC SAIL or BSAI cylinder for positive load holding.
To match this exact ISO 15552 replacement, specify an 80mm bore, 400mm nominal stroke, 30mm adjustment range, PT tapered port thread, and the -S magnet option. The available mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2. For stroke lengths of 300mm or more, always support the load with an external guide to protect the rod from bending.

- ✓ 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 SAIJ80AX400-30S FAQ
At 0.5 MPa it provides 2513N push and 2268N pull force. At 0.7 MPa, the push force increases to 3518N, with a maximum rated push of 4523N at 0.9 MPa.
The rear adjusting screw acts as a mechanical stopper that shortens the retract stroke. For this 400mm model, it creates a usable travel window of 370-400mm, allowing precise end-position tuning at commissioning without changing the cylinder.
