About the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX290-30S
The AirTAC SAIJ100X290-30-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, allowing you to dial back the 290 mm nominal stroke by up to 30 mm. This yields a usable travel window of 260 to 290 mm, providing exact end-position tuning during commissioning without the need to swap out the physical cylinder. It delivers substantial thrust, generating 5497 N of push force at 0.7 MPa and 3927 N at 0.5 MPa.
This specific SKU features a SUS304 stainless steel rod (material code B) for superior corrosion resistance and includes a built-in magnet for position sensing. It works seamlessly with AirTAC CMSE reed switches and DMSE solid-state sensors via the dual sensor grooves on the extruded aluminum barrel. The rear adjuster acts purely as a mechanical stop to set the retract end; it does not lock the load, so maintain live air pressure or use an external rod lock for holding.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX290-30S Is Used
Machine Changeover
Dial in the 260-290 mm travel window during product size transitions without swapping cylinders or adding external stopper blocks.
End-Position Tuning
Fine-tune the retract stroke by up to 30 mm at commissioning to perfect the seating pressure of large forming or clamping fixtures.
Variable End Stops
Adjust the rear mechanical stop on the fly for automated lines processing varying material lengths, ensuring precise indexing.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX290-30S the Right Cylinder?
Choose this 100 mm bore adjustable-stroke cylinder when your application requires high force combined with variable end-stops for product size changeovers. If you need slightly less force, stepping down to an 80 mm bore yields 3518 N of push force at 0.7 MPa. Conversely, a 125 mm bore provides 8590 N at 0.7 MPa for heavier loads. The adjustable rear screw is ideal for fine-tuning the travel window to 260-290 mm on the fly, which is far more efficient than machining custom spacers or ordering a fixed-stroke SAI cylinder.
Because the 290 mm stroke is substantial, the 25 mm rod diameter and M20x1.5 rod thread provide robust support, but an external guide is still recommended to prevent side-loading damage on long unsupported extensions. This SAIJ model uses a PT tapered port thread and supports a reduced mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2), omitting FB, CA, CB, and CR options. It is dimensionally interchangeable per ISO 15552.

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 SAIJ100BX290-30S FAQ
The rear adjuster screw lets you shorten the effective stroke by up to 30 mm. This creates a usable travel window of 260 to 290 mm, allowing you to fine-tune the retract end position without replacing the cylinder.
At an operating pressure of 0.7 MPa, the SAIJ100X290-30-S generates 5497 N of push force and 5497 N of pull force. At 0.5 MPa, it provides 3927 N of push force.
