About the Airtac SAIJ80 Adjustable Cylinder SAIJ80X115-30S
The AirTAC SAIJ80X115-30-S is a double-acting, single-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It delivers 2513N of push force at 0.5 MPa and features a 25mm carbon steel piston rod with an M20x1.5 thread. By turning the rear screw, you achieve an 85-115mm usable travel window, enabling precise end-position tuning without adding external stops.
This -S variant includes a magnet for position sensing and is compatible with AirTAC CMSE reed and DMSE electronic solid-state switches. It utilizes a PT tapered port thread (G3/8) and relies on adjustable air cushions at both ends to decelerate the load. The rear adjuster functions strictly as a travel stop, meaning it will not hold the load safely without continuous live air pressure.

Where the Airtac SAIJ80 Adjustable Cylinder SAIJ80X115-30S Is Used
Product Changeovers
Quickly dial in the 85-115mm stroke window during format size changes on packaging lines without replacing the cylinder.
End-Position Tuning
Fine-tune the exact retract distance during machine commissioning to prevent crushing delicate workpieces.
Adjustable Ejector
Vary the ejection reach on an assembly station to accommodate different part depths using the rear stopper screw.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80X115-30S the Right Cylinder?
Select this 80mm bore when an application requires higher thrust than a 63mm cylinder (which provides 1559N push at 0.5 MPa) but has physical constraints preventing the use of a 100mm bore. The 30mm adjustment range is particularly useful for product changeovers on a line, allowing operators to dial in the exact 85-115mm end-stop mechanically during commissioning rather than swapping out a fixed-stroke SAI cylinder.
To achieve a direct ISO 15552 replacement, match the 80mm bore, 115mm nominal stroke, 30mm adjustment code, PT port thread, and the -S magnet option. Because the nominal stroke of 115mm is relatively short, side-load risks are minimized, though the robust 25mm rod further helps absorb incidental radial stress. For applications requiring true load-holding without live air, consider an AirTAC SAIL pneumatic lock or BSAI clamp-lock cylinder instead of relying on the adjuster.
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 SAIJ80X115-30S FAQ
At 0.5 MPa operating pressure, this 80mm bore cylinder provides 2513N of push force and 2268N of pull force. At a maximum 1.0 MPa pressure, it can deliver up to 513 kgf.
The rear adjuster screw acts as a mechanical stop, allowing you to shorten the effective travel from the 115mm nominal stroke down to as little as 85mm. This creates an 85-115mm adjustable window for fine-tuning the retract end position without swapping cylinders.
