About the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX475-100
The AirTAC SAIJ100X475-100 is a double-acting ISO 15552 profile cylinder featuring a rear mechanical stroke adjuster. By integrating a 100mm adjustment mechanism at the retract end, this model creates a versatile usable travel window between 375mm and 475mm, allowing you to dial in the exact end position without swapping hardware.
Built with a corrosion-resistant SUS420J2 stainless steel piston rod and PT threaded ports, it is designed for demanding environments. The extruded aluminum barrel includes sensor grooves on both sides for flexible switch placement. Note that the rear adjuster acts purely as a travel stop for end-position tuning, not a load-holding lock; for dead-stop positioning under live air, it excels, but maintaining load without pressure requires an external pilot-operated check valve or a SAIL lock cylinder.

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 SAIJ100AX475-100 Is Used
Product Changeover Dials
Leverage the 100mm adjustment range to switch between different product lengths on a single line, shifting the retract end-stop from 375mm to 475mm without disassembling the cylinder assembly.
Variable Forming Stops
Control material forming or bending depth on the fly, using the adjustable travel window to accommodate multiple material thicknesses in high-speed automated equipment.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX475-100 the Right Cylinder?
Conversely, heavier loads might require the 125mm bore, which provides 6136N at 0.5 MPa. The 100mm adjustment range on this specific SKU allows a massive 100mm trim, offering unmatched flexibility for prototyping or varying product sizes.
Because the 475mm stroke is substantial, the 25mm rod diameter and M20x1.5 rod thread provide robust support, but long unsupported strokes still require an external guide to prevent side-loading damage. This model uses a reduced mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2), omitting FB, CA, CB, and CR options. It is dimensionally interchangeable per ISO 15552. Configuration includes PT tapered ports, no magnet, and the SUS420J2 (A) rod material. If you need position hold without live air, consider the SAIL or BSAI clamp-lock series instead.
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 SAIJ100AX475-100 FAQ
At 0.9 MPa, the push force increases to 7068N.
The rear adjuster acts as a mechanical stop that allows you to shorten the 475mm nominal stroke by up to 100mm, creating a usable travel window of 375-475mm. It functions as a travel stop and does not lock or hold the load without live air pressure.
