About the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX260-30S
The AirTAC SAIJ80X260-30-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that creates a 230 to 260 mm usable travel window. It delivers 2513 N of push force and 2268 N of pull force at 0.5 MPa, making it suited for heavy-duty positioning. The extruded aluminum barrel includes sensor grooves on both sides, and this -S variant includes a magnet for switching.
This model uses a SUS420J2 stainless steel rod for superior wear resistance and features PT tapered port threads. The rear adjuster screw acts purely as a mechanical stop to fine-tune the end position at commissioning; it does not lock or hold the load without live air pressure. For load-holding requirements, consider the SAIL or BSAI series instead.

Where the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX260-30S Is Used
Product Changeover
Dial in the exact end-stop between 230 and 260 mm during line changeovers without replacing the cylinder or adding shims.
Machine Setup
Fine-tune the retract position during commissioning to perfect crushing or pressing distances on heavy machinery.
Variable End Stops
Adjust the travel limit on the fly for diverter arms handling different package sizes on a packaging line.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX260-30S the Right Cylinder?
Choose this 80 mm bore when a 50 mm bore (982 N push at 0.5 MPa) lacks the thrust for your payload, but a 100 mm bore is physically too large. The 30 mm adjustment range is ideal for product changeovers, allowing you to trim the 260 mm stroke back to 230 mm without adding external stops or swapping the cylinder.
At 260 mm of travel, the 25 mm rod and M20x1.5 thread handle substantial side loads, but an external guide is recommended for heavy unsupported loads. This SAIJ configuration uses PT ports, a SUS420J2 rod, and supports mounting sets Basic, FA, LB, TC, FTC, TCM1, and TCM2. It is dimensionally interchangeable per ISO 15552. The integrated magnet works with AirTAC CMSE reed and DMSE electronic sensors.

- ✓ 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 SAIJ80AX260-30S FAQ
At 0.5 MPa operating pressure, this 80 mm bore cylinder provides 2513 N of push force and 2268 N of pull force. It can reach up to 4523 N of push force at 0.9 MPa.
The rear adjuster screw acts as a mechanical stop, allowing you to shorten the effective travel from 260 mm down to 230 mm. It only sets the end position and does not lock the load without continuous air pressure.
