About the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX260-20S
The AirTAC SAIJ80X260-20-S is a double-acting, single-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It delivers a robust 2513N push force at 0.5MPa and features a 260mm nominal stroke that can be fine-tuned down by up to 20mm, providing a usable travel window of 240-260mm. This built-in adjustability allows you to dial in exact end positions during commissioning without adding external stopper blocks.
This specific configuration features a SUS420J2 stainless steel rod (code A) for enhanced corrosion resistance and includes a magnet (-S) for use with AirTAC CMSE reed and DMSE electronic sensors. The extruded aluminum barrel integrates sensor grooves on both sides, and the unit operates at speeds between 30-800mm/s with PT tapered port threads.

Where the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX260-20S Is Used
Machine Changeover
Quickly fine-tune the 240-260mm stroke end-position during product size changes without physically replacing the cylinder or adding external stops.
End-Stop Tuning
Perfect for precision pressing or clamping tasks where the exact bottoming point must be dialed in within a 20mm window during commissioning.
Variable Positioning
Ideal for automated assembly lines requiring adjustable retraction limits to accommodate varying part heights on the fly.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX260-20S the Right Cylinder?
Choose this 80mm bore when an application requires substantial force, stepping up from the 50mm bore that provides 982N push force at 0.5MPa. The adjustable stroke is ideal for product changeovers on a line, letting you shift the end-stop by up to 20mm without swapping the cylinder. For a fixed end position, the standard SAI cylinder is sufficient, but the SAIJ variant provides superior setup flexibility.
When replacing an ISO 15552 cylinder, match the 80mm bore, 260mm stroke, PT port threads, and the -S magnet requirement. Note that the SAIJ mounting set is limited to Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR. Because the stroke is 260mm, the 25mm rod diameter should be guided externally to prevent excessive side-loading. The rear adjuster acts only as a travel stop and does not hold the load without live air; for dead-load holding, use an external rod lock or consider the SAIL or BSAI series.
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 SAIJ80AX260-20S FAQ
At 0.5MPa operating pressure, this 80mm bore cylinder provides 2513N of push force and 2268N of pull force. At 0.7MPa, the push force increases to 3518N.
The rear adjuster screw allows you to shorten the effective stroke by up to 20mm, creating a usable travel window of 240-260mm from the 260mm nominal stroke. It acts as a mechanical stop and does not lock the load without continuous air pressure.
