About the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX350-100
The AirTAC SAIJ100X350-100 is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, delivering a robust 3927N push force at 0.5MPa. By turning the rear stopper screw, you achieve a usable travel window between 250 and 350mm, allowing precise end-position tuning without swapping out the physical cylinder. The extruded aluminum barrel features sensor grooves on both sides for straightforward detection integration.
This specific configuration utilizes a SUS304 stainless steel rod (material code B) for enhanced corrosion resistance, paired with PT tapered port threads. It supports a speed range of 30-800mm/s and relies on variable air cushions at both ends to decelerate the load smoothly. The rear adjuster acts purely as a travel stop and does not hold the load without live air pressure.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX350-100 Is Used
Machine Setup Changeover
Dial in the exact end-stop between 250 and 350mm during machine commissioning to accommodate new product dimensions without physically swapping the cylinder.
Variable End-Position Tuning
Fine-tune the retract stroke on the fly to adjust stopping distances for precision assembly operations without adding external mechanical stops.
Corrosive Environment Actuation
Leverage the SUS304 stainless steel rod to reliably drive 3927N of push force in manufacturing cells where moisture or corrosive elements are present.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX350-100 the Right Cylinder?
Choose this adjustable-stroke model over a fixed SAI cylinder when your application requires frequent commissioning fine-tuning or variable end-stops during product changeovers. If you need slightly less force, stepping down to an 80mm bore yields 2513N at 0.5MPa. For heavier demands, a 125mm bore provides 6136N. Because the nominal stroke is 350mm, an external guide is recommended to manage side loads and prevent rod deflection over the extended travel distance.
For a true ISO 15552 replacement match, verify the 100mm bore, 350mm stroke, 100mm adjustment range, PT port threads, and the SUS304 rod material. Note that SAIJ uses a reduced mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2) and omits FB, CA, CB, and CR mounts. If your process requires holding the load position without continuous live air, this cylinder's adjuster will not suffice; consider an AirTAC SAIL or BSAI locking cylinder instead.

- ✓ 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 SAIJ100BX350-100 FAQ
At 0.5MPa operating pressure, this 100mm bore cylinder provides a push force of 3927N and a pull force of 3681N. At the maximum 1.0MPa pressure, it can deliver up to 801kgf of push force.
The rear adjusting screw acts as a stopper that lets you trim the effective travel back from the 350mm nominal stroke, creating a usable window of 250 to 350mm. This stopper only sets the travel end and does not lock or hold the load without live air pressure.
