About the Airtac SAIJ80 Adjustable Cylinder SAIJ80X260-100
The AirTAC SAIJ80X260-100 is a double-acting, single-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It provides a 160 to 260 mm usable travel window, allowing you to dial back the nominal 260 mm stroke by up to 100 mm during commissioning. Delivering 4523 N of push force at 0.9 MPa, it handles demanding workloads while utilizing a G3/8 port and a 25 mm carbon steel rod.
This adjustable-stroke design eliminates the need to swap cylinders or bolt on external stops when fine-tuning end positions. The extruded aluminum barrel features sensor grooves on both sides, and the mounting hardware is compatible with Basic, FA, LB, TC, FTC, TCM1, and TCM2 ISO 15552 interfaces. Note that the rear adjuster functions strictly as a travel stop, not a load-holding lock.

Where the Airtac SAIJ80 Adjustable Cylinder SAIJ80X260-100 Is Used
Product Changeover
Quickly adapt machinery for varying package sizes by dialing the rear adjuster within the 160-260 mm travel window without changing hardware.
End-Position Tuning
Fine-tune the exact retract position during machine commissioning to perfect seating or clamping forces without adding external mechanical stops.
Assembly Line Formatting
Handle heavy workpiece pushing tasks with 4523 N of thrust at 0.9 MPa while retaining the flexibility to reposition the end-stop for different product runs.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80X260-100 the Right Cylinder?
Choose this 80 mm bore when an application requires substantial thrust, such as 4523 N at 0.9 MPa, but demands a highly flexible end-of-stroke position. The 100 mm adjustment window is ideal for product-size changeovers on a line. If less force is needed, stepping down to a 63 mm bore yields 2805 N at 0.9 MPa. Because the nominal stroke is 260 mm, external guiding is recommended to manage side-load on the extended rod.
For a drop-in ISO 15552 replacement, match the 80 mm bore, 260 mm stroke, 100 mm adjustment, PT tapered port threads, and carbon steel rod. Since no magnet is specified, position sensing is not enabled; adding an -S suffix enables CMSE reed or DMSE electronic sensors. If true load-holding without live air pressure is required, select the SAIL or BSAI series instead, as the SAIJ adjuster will not hold a load.

- ✓ 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 SAIJ80X260-100 FAQ
The rear adjuster acts as an external stopper that trims the effective travel. For this model, you can shorten the 260 mm nominal stroke by up to 100 mm, providing a usable travel window of 160 to 260 mm. It acts as a travel stop, not a lock, and does not hold the load without live air pressure.
At an operating pressure of 0.9 MPa, the SAIJ80X260-100 provides a push force of 4523 N and a pull force of 4071 N. At 0.5 MPa, it delivers 2513 N of push force.
