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. This 100 mm bore actuator delivers a robust 7068N of push force at 0.9 MPa, making it well-suited for heavy-duty positioning tasks. 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.

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.
Commissioning Tuning
Fine-tune the rear mechanical stop during initial setup to perfectly align heavy 7068N pushing forces without adding external physical stops.
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. If you need less force, stepping down to an 80 mm bore yields 4523N of push force at 0.9 MPa. 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
This 100 mm bore cylinder provides a push force of 7068N and a pull force of 3681N at an operating pressure of 0.9 MPa.
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.
