About the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX260-10
The AirTAC SAIJ80X260-10 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to fine-tune the end-of-travel position. With a nominal 260 mm stroke and a 10 mm adjustment range, it provides a usable travel window of 250-260 mm for precise machine setup.
This model is equipped with a SUS304 stainless steel rod (option B) for superior corrosion resistance in humid or washdown environments. It uses PT tapered G3/8 ports and relies on a 25 mm rod with an M20x1.5 thread. The extruded aluminum barrel includes sensor grooves on both sides, allowing you to easily add CMSE reed or DMSE electronic switches if position feedback is needed later.

Theoretical Output Force (Ø80mm)
| Pressure | Push force | Pull force |

| 0.5 MPa | 2268 N | 2268 N |
| 0.7 MPa | 3175 N | — |
| Max (@1.0 MPa) | 463 kgf | |
Double-rod model: the rod passes through the rear cover, so both piston faces lose rod area and push is shown at the annular-area value. Actual usable force is lower than theoretical due to friction and back-pressure. Size with a safety margin.

Where the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX260-10 Is Used
Machine Changeover
Dial in the 250-260 mm travel window during product size changes to set new end positions without replacing the entire cylinder.
End-Position Tuning
Fine-tune the retract stroke at commissioning to absorb mechanical tolerances and achieve exact positioning without external stops.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX260-10 the Right Cylinder?
Choose this adjustable-stroke variant when your application requires variable end-stops or precise fine-tuning during commissioning without the need to physically swap out a fixed-stroke SAI cylinder. If your process demands less force, stepping down to a 63 mm bore yields 1559 N at 0.5 MPa; conversely, a 100 mm bore provides 3927 N for heavier loads. Because the stroke is 260 mm, ensure your mounting configuration supports the load adequately to prevent rod side-loading and premature wear.
The rear adjuster on this SAIJ cylinder acts strictly as a mechanical travel stop to set deceleration alongside the adjustable air cushions; it does not lock or hold the load without continuous live air pressure. For true fail-safe load-holding, consider an AirTAC SAIL pneumatic lock or BSAI clamp-lock cylinder. This model is dimensionally interchangeable per ISO 15552 and supports a mounting subset of Basic, FA, LB, TC, FTC, TCM1, and TCM2.

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 SAIJ80BX260-10 FAQ
At the maximum 1.0 MPa pressure, it can deliver up to 513 kgf.
The rear adjuster screw lets you shorten the nominal 260 mm stroke by up to 10 mm, creating a 250-260 mm usable travel window. This allows precise end-position tuning during setup, though the adjuster acts only as a stop and does not hold the load without air pressure.
