About the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX260-40
The AirTAC SAIJ100X260-40 is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a 220-260 mm usable travel window, allowing you to dial back the 260 mm nominal stroke by up to 40 mm during commissioning without swapping the cylinder or adding external stops. Operating at 0.5 MPa, it delivers 3927 N of push force and 3681 N of pull force.
This unit ships with a SUS304 stainless steel rod for corrosion resistance and uses PT tapered port threads. The extruded aluminum barrel includes sensor grooves on both sides for CMSE reed and DMSE electronic switches. The rear adjuster acts purely as a travel stop to fine-tune end positions, meaning it does not hold the load without live air pressure.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX260-40 Is Used
Product Changeover
Dial in the exact end position for different product sizes on a single machine line using the 40 mm adjustment window.
Variable End Stops
Fine-tune the retract stroke on packaging conveyors to accommodate varying package lengths without external stopper hardware.
Machine Setup
Trim the effective travel during initial commissioning to prevent over-travel and optimize cycle timing.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX260-40 the Right Cylinder?
Choose this 100 mm bore when your application requires substantial thrust, stepping up from the 80 mm bore which provides 2513 N of push force at 0.5 MPa. The adjustable stroke is ideal for product changeovers on a line where the exact end-of-stroke position varies by up to 40 mm, saving the effort of machining custom spacers. For load-holding without continuous air pressure, consider the SAIL or BSAI series, as the SAIJ adjuster is not a locking device.
When integrating this cylinder, note the reduced SAIJ mounting set: Basic, FA, LB, TC, FTC, TCM1, and TCM2, which omits the FB, CA, CB, and CR options. Because the 260 mm stroke is significant and the rod carries a M20x1.5 thread, long unsupported strokes still require an external guide to manage side loads. This model is dimensionally interchangeable per ISO 15552.
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 SAIJ100 Adjustable Cylinder SAIJ100BX260-40 FAQ
The rear adjusting screw lets you shorten the effective stroke by up to 40 mm, providing a usable travel window of 220 to 260 mm. It acts as a mechanical stop to fine-tune the retract end position without changing the cylinder itself.
At 0.5 MPa operating pressure, the SAIJ100X260-40 provides 3927 N of push force and 3681 N of pull force. It can reach up to 7068 N of push force at 0.9 MPa.
