About the Airtac SAIJ80 Adjustable Cylinder SAIJ80X260-30S
The AirTAC SAIJ80X260-30-S is a double-acting, single-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It provides a 230-260 mm usable travel window, allowing you to dial back the nominal 260 mm stroke by up to 30 mm during commissioning. Delivering 2513 N of push force at 0.5 MPa, it fits perfectly into medium-to-heavy pneumatic setups.
This variant features a carbon steel piston rod and a magnetic piston for use with AirTAC CMSE reed and DMSE electronic sensors. The extruded aluminum barrel includes sensor grooves on both sides, and fluid supply is via a PT G3/8 threaded port. The rear stopper sets the retracted end position but does not lock the load without live air pressure.

Where the Airtac SAIJ80 Adjustable Cylinder SAIJ80X260-30S Is Used
Product Changeovers
Dial in the 230-260 mm stroke window quickly during format changes on packaging lines without physically swapping out the actuator.
End-Stop Calibration
Fine-tune the retracted position during machine commissioning to prevent mechanical crashes and achieve precise positioning.
Variable Diverter Arms
Adjust the stroke length on diverter gates to accommodate different package sizes moving down the line.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80X260-30S the Right Cylinder?
Choose this 80 mm bore when an application requires more thrust than the 50 mm bore (which provides 982 N push at 0.5 MPa) but does not need the full 3927 N push of a 100 mm cylinder. The adjustable 30 mm window is ideal for product changeovers on a line, letting you fine-tune the end position without swapping the cylinder or adding external stops. If the machine requires holding a load without continuous air pressure, use a SAIL or BSAI lock cylinder instead, as the SAIJ adjuster is strictly a travel stop.
For an exact ISO 15552 replacement, match the 80 mm bore, 260 mm stroke, 30 mm adjustment, G3/8 PT port, and the -S magnet option. Mounting choices are limited to Basic, FA, LB, TC, FTC, TCM1, and TCM2. Because the 260 mm stroke is substantial, ensure external guidance is used to prevent excessive side-loading on the 25 mm 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 SAIJ80X260-30S FAQ
At 0.5 MPa it provides 2513 N of push force and 2268 N of pull force. At 0.7 MPa the push force increases to 3518 N.
The rear adjuster acts as a mechanical stop, allowing you to shorten the 260 mm stroke by up to 30 mm, yielding a 230-260 mm travel window. It only sets the end position and does not lock the load.
