About the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX260-30
The AirTAC SAIJ80X260-30 is a double-acting, single-rod ISO 15552 profile cylinder featuring a rear stroke adjuster. It provides a nominal 260 mm stroke with a 30 mm adjustment range, yielding a usable travel window of 230-260 mm for exact end-position tuning during commissioning. It delivers 2513 N of push thrust at 0.5 MPa and utilizes a PT tapered G3/8 port.
This model features an SUS420J2 stainless steel rod for enhanced corrosion resistance and includes variable air cushions at both ends. The rear adjuster acts strictly as a mechanical stop to fine-tune the retract position without adding external stops; it is not a lock and will not hold the load without live air pressure. For load-holding requirements, consider the SAIL or BSAI series.

Where the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX260-30 Is Used
Machine Changeover
Dial in the 230-260 mm travel window during product size transitions without physically swapping the cylinder or adding external mechanical stops.
Variable End Stops
Fine-tune the retract position on packaging lines to accommodate different package lengths on the fly using the rear adjustment screw.
Assembly Actuation
Provide 2513 N of push force at 0.5 MPa for pressing or lifting tasks, with the flexibility to trim the stroke back up to 30 mm for setup clearance.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX260-30 the Right Cylinder?
Choose this 80 mm bore when 50 mm (982 N push at 0.5 MPa) lacks the force for your workload, but 100 mm (3927 N) is oversized. The 30 mm adjuster is ideal for product changeovers on a line, allowing you to dial in the exact 230-260 mm travel window without swapping the cylinder. Since the 260 mm stroke exceeds 300 mm is false here, but for longer unsupported travels, an external guide is recommended to manage side-load stress on the 25 mm rod.
To match this ISO 15552 cylinder for a replacement, verify the 80 mm bore, 260 mm stroke, 30 mm adjustment, PT G3/8 port, and the reduced SAIJ mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2). Note that this configuration omits the -S magnet, so it does not support CMSE or DMSE electronic sensors without modification.
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 SAIJ80AX260-30 FAQ
The rear adjuster screw allows you to shorten the effective stroke by up to 30 mm. This creates a usable travel window of 230-260 mm, letting you fine-tune the end position at commissioning without changing the cylinder.
At 0.5 MPa operating pressure, the SAIJ80X260-30 provides 2513 N of push thrust and 2268 N of pull thrust. At the maximum 1.0 MPa pressure, it delivers 4523 N of push force.
