About the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX90-50S
The AirTAC SAIJ100X90-50-S is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a 3927N push force at 0.5 MPa and uses a SUS304 stainless steel rod for superior corrosion resistance. The integrated magnet supports CMSE reed and DMSE electronic sensors for precise position feedback.
With a 90mm nominal stroke and a 50mm adjustment range, this model yields a highly versatile 40-90mm usable travel window. This wide tuning band is ideal for prototyping or product changeovers, letting you dial in the exact end position without swapping the cylinder. It features PT tapered port threads and a 25mm rod diameter to handle substantial side loads.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX90-50S Is Used
Product Changeovers
Quickly adapt a packaging line to different carton lengths by dialing the stroke back from 90mm to 40mm without changing hardware.
Prototype Positioning
Fine-tune the exact end-of-stroke stop during machine commissioning to perfect a 100mm bore pressing operation without external stops.
Sensor-Driven Sorting
Leverage the -S magnet with DMSE solid-state sensors to confirm position across the 40-90mm adjustable travel window on a diverter gate.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX90-50S the Right Cylinder?
Select this 100mm bore cylinder when your application requires substantial thrust—3927N at 0.5 MPa or 5497N at 0.7 MPa—and on-the-fly end-position tuning. If you need less force, stepping down to a 63mm bore yields 1559N at 0.5 MPa, while an 80mm bore provides 2513N. The SAIJ100X90-50-S is chosen over a fixed-stroke SAI cylinder when a 40-90mm travel window is required to accommodate varying product sizes on a single line.
Because the 90mm nominal stroke is relatively short, side-loading is less of a concern than with longer strokes, but always ensure adequate guiding for heavy loads. Note that the rear adjuster acts as a travel stop, not a lock; the cylinder cannot hold its load without live air. For load-holding requirements, consider an external pilot-operated check valve or the SAIL pneumatic lock series. This SKU is dimensionally interchangeable with ISO 15552 cylinders and uses the SAIJ mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2), omitting FB, CA, CB, and CR options.

- ✓ 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 SAIJ100BX90-50S FAQ
At a 0.5 MPa operating pressure, this 100mm bore cylinder provides 3927N of push force and 3681N of pull force. Increasing the pressure to 0.7 MPa yields 5497N of push force.
The rear adjuster screw acts as a mechanical stop, allowing you to trim the effective travel anywhere within a 40-90mm window. It decelerates the end position but does not lock the load without continuous air pressure.
