About the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX475-40
The AirTAC SAIJ100X475-40 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster, letting you dial the effective travel back by up to 40 mm. This yields a usable 435-475 mm end-position window, ideal for fine-tuning machine setups without swapping hardware. It features a SUS304 stainless steel rod and a PT tapered port.
The extruded aluminum barrel includes dual sensor grooves, though no magnet is installed. The rear screw acts purely as a travel stop, so you still need live air to hold loads.

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 SAIJ100BX475-40 Is Used
Machine Setup Tuning
Fine-tune the 435-475 mm travel window during commissioning to achieve precise end-positioning without adding external stopper blocks.
Product Size Changeover
Quickly adapt the cylinder's effective stroke on automated lines when packaging or product dimensions shift.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100BX475-40 the Right Cylinder?
Choose this 100 mm bore when 80 mm falls short (2513 N at 0.5 MPa) but 125 mm is excessive. The 40 mm adjustment window is perfect for product changeovers. For load-holding without air, use SAIL or BSAI. Match ISO 15552 dimensions: 100 mm bore, 475 mm stroke, PT port, Basic/LB/TC mounts. At 475 mm stroke, use an external guide to manage side loads.
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 SAIJ100BX475-40 FAQ
At 0.9 MPa, the push force increases to 7068 N.
The rear adjuster screw lets you shorten the 475 mm nominal stroke by up to 40 mm, creating a 435-475 mm usable travel window. It functions as a mechanical stop, not a lock.
