About the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX475-100
The AirTAC SAIJ80X475-100 is a double-acting, double-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. This adjustability allows operators to dial in exact retract end positions during commissioning or product changeovers without swapping out the entire actuator.
Built with an SUS420J2 stainless steel rod (option A) and PT tapered port threads, this 80mm bore unit handles demanding environments while resisting corrosion. The extruded aluminum barrel incorporates sensor grooves on both sides for flexible mounting of CMSE or DMSE switches. Because the stroke reaches 475mm, the 25mm rod diameter should be paired with an external guide to prevent excessive side-loading on long unsupported extensions.

Theoretical Output Force (Ø80mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 2268 N | 2268 N |
| 0.7 MPa | 3175 N | — |
| Max (@1.0 MPa) | 463 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 SAIJ80 Adjustable Cylinder SAIJ80AX475-100 Is Used
Variable End-Stop Positioning
Ideal for packaging lines where the retract position must be shifted precisely between different carton depths, utilizing the 375-475mm travel window without mechanical rework.
Machine Changeover Calibration
Enables operators to fine-tune the stroke during product family transitions, using the rear 100mm adjustment screw to set exact stopping points rapidly.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX475-100 the Right Cylinder?
Selecting this 80mm bore actuator makes sense when an application demands high thrust combined with variable retract stops. The SAIJ80X475-100 is chosen over a fixed-stroke SAI cylinder when machinery requires frequent product-size changeovers, allowing the rear screw to trim the 475mm stroke back to as little as 375mm on the fly.
As a dimensionally interchangeable ISO 15552 cylinder, it matches standard mounting footprints using a reduced set of accessories: Basic, FA, LB, TC, FTC, TCM1, and TCM2 (omitting FB, CA, CB, and CR). Note that the rear adjuster functions strictly as a travel stop and does not hold the load without live air; for fail-safe load holding, consider an AirTAC SAIL or BSAI lock cylinder. Operating speed ranges from 30-800mm/s, regulated by adjustable air cushions at both ends.

- ✓ 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 SAIJ80 Adjustable Cylinder SAIJ80AX475-100 FAQ
At a maximum 0.9 MPa, the push force increases to 4523N.
The rear adjuster acts as an external stopper that shortens the effective travel from the 475mm nominal stroke, creating a usable 375-475mm window. It sets the end position but does not lock the load without continuous air pressure.
