About the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX475-10
The AirTAC SAIJ100X475-10 is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a 465-475mm usable travel window, trimming the 475mm nominal stroke by up to 10mm. Delivering 3927N of push force at 0.5MPa, it suits heavy-duty positioning tasks. The extruded aluminum barrel includes dual sensor grooves, and the SUS304 stainless steel rod resists corrosion in humid environments.
This model uses PT tapered port threads (G1/2) and offers adjustable pneumatic cushioning at both ends. The rear adjuster acts purely as a mechanical stop for end-position tuning; it does not lock the load. For position holding without live air pressure, consider an AirTAC SAIL or BSAI series cylinder.

Where the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX475-10 Is Used
Machine Setup Tuning
Dial in the exact 465-475mm retract position during initial commissioning to align heavy fixtures without machining spacer plates.
Product Changeover
Quickly adjust the end-stop for different package sizes on a packaging line by turning the rear screw during format resets.
Heavy Material Handling
Push substantial loads with 3927N of force at 0.5MPa while relying on the SUS304 rod for durability in demanding industrial environments.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX475-10 the Right Cylinder?
Choose this 100mm bore when an 80mm cylinder (2513N push at 0.5MPa) lacks thrust or a 125mm bore is physically too large. The 10mm adjustment range is ideal for fine-tuning the retract end during machine setup or product changeover without adding external stops. Because the 475mm stroke is substantial, always use an external guide to support the load and mitigate side-load stress on the 25mm rod. This cylinder is dimensionally interchangeable per ISO 15552 and omits the FB, CA, CB, and CR mounting styles, offering Basic, FA, LB, TC, FTC, TCM1, and TCM2 mounts.
Quick checklist
- ✓ Required force at your working pressure
- ✓ 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 SAIJ100BX475-10 FAQ
At 0.5MPa operating pressure, this 100mm bore cylinder provides 3927N of push force and 3681N of pull force. At 0.9MPa, the push force increases to 7068N.
The rear adjuster screw lets you shorten the effective travel from the nominal 475mm down to 465mm. It functions as a mechanical stop to fine-tune the end position and does not hold the load without continuous air pressure.
