About the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX90-75
The AirTAC SAIJ100X90-75 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to trim the effective travel down to a 15-90 mm window. The extruded aluminum barrel includes sensor grooves on both sides for flexible switch mounting.
Equipped with a SUS304 stainless steel rod (option B) and PT tapered ports, this model handles demanding environments while providing excellent corrosion resistance. The rear adjuster acts purely as a mechanical stop to fine-tune the end position during commissioning; it does not hold the load without live air pressure. For load-holding requirements, consider exploring the SAIL or BSAI series instead.

Theoretical Output Force (Ø100mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 3682 N | 3682 N |
| 0.7 MPa | 5154 N | — |
| Max (@1.0 MPa) | 751 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 SAIJ100 Adjustable Cylinder SAIJ100BX90-75 Is Used
Machine Changeovers
Dial in the exact end-stop for different product sizes on a single line, utilizing the 15-90 mm travel window to avoid swapping out entire cylinders.
Heavy Assembly Presses
Leverage the 100 mm bore thrust and SUS304 rod for robust, corrosion-resistant actuation in demanding industrial assembly and pressing stations.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX90-75 the Right Cylinder?
Choose this 100 mm bore adjustable cylinder when your application requires substantial thrust—pushing 7068N at 0.9 MPa—and a variable end-stop. The SAIJ100X90-75 is selected over a fixed SAI cylinder when machine setups require frequent product changeovers or precise end-position tuning without swapping actuators.
Because the nominal stroke is under 300 mm, side-load risks are moderate, but always ensure proper guiding for heavy loads. When replacing an ISO 15552 cylinder, match the 100 mm bore, 90 mm stroke, 75 mm adjustment range, PT port type, and the SUS304 rod material. This actuator supports the SAIJ mounting subset: Basic, FA, LB, TC, FTC, TCM1, and TCM2.

- ✓ 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 SAIJ100BX90-75 FAQ
The rear adjuster acts as a mechanical stop that lets you shorten the 90 mm nominal stroke by up to 75 mm, creating a usable travel window of 15 to 90 mm. It sets the end position but does not lock or hold the load without live air pressure.
