About the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX475-30
The AirTAC SAIJ100X475-30 is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, allowing you to fine-tune the end position without swapping out the unit. It provides a usable travel window of 445 to 475 mm, giving you 30 mm of flexibility to dial in the exact retract distance during commissioning. This bore size delivers substantial thrust, pushing 5497 N and pulling 3681 N at 0.7 MPa.
Built with a SUS420J2 stainless steel rod, it handles demanding environments while resisting corrosion. The extruded aluminum barrel features sensor grooves on both sides for flexible mounting of CMSE or DMSE switches. Remember that the rear adjuster acts purely as a travel stop for deceleration and positioning; it does not lock the load without continuous air pressure.

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 SAIJ100AX475-30 Is Used
Product Changeovers
Quickly shift the retract end-stop by up to 30 mm when running different product sizes on the same line, avoiding the need to physically swap out cylinders.
Long-Stroke Handling
Drive heavy materials over the 445-475 mm travel range, using the external adjuster to perfectly seat parts without over-travel damage.
Is the Airtac SAIJ100 Adjustable Cylinder SAIJ100AX475-30 the Right Cylinder?
The adjustable 445-475 mm window is ideal for product changeovers on a line, letting you shift the end-stop on the fly rather than installing a fixed SAI cylinder of a different length. For exact ISO 15552 interchangeability, match the 100 mm bore, 475 mm nominal stroke, 30 mm adjuster, PT tapered ports, and your required mounting set.
Because the 475 mm stroke is long, the 25 mm diameter rod will experience leverage forces under side-loading; always use an external guide rail to support the load. This model supports Basic, FA, LB, TC, FTC, TCM1, and TCM2 mounts. If your application requires holding the load statically without live air, select a SAIL or BSAI cylinder instead, as the SAIJ adjuster is not a locking mechanism.
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 SAIJ100AX475-30 FAQ
At 0.9 MPa, the push force increases to 7068 N.
The rear adjuster acts as an external stopper that shortens the effective stroke. For this model, it creates a usable travel window of 445 to 475 mm, allowing you to trim the retract distance during setup without changing the cylinder.
