About the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX450-100S
The AirTAC SAIJ80X450-100-S is a double-acting, double-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It provides a nominal 450 mm stroke that can be fine-tuned backward by up to 100 mm, creating a usable travel window of 350-450 mm.
This specific configuration features a SUS420J2 stainless steel rod (material code A) for enhanced corrosion resistance and includes a magnet (-S) for use with CMSE reed or DMSE electronic solid-state sensors. The extruded aluminum barrel incorporates sensor grooves on both sides, and the rear adjuster acts purely as a mechanical stop for end-position tuning, not as a lock to hold the load without live air.

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 SAIJ80AX450-100S Is Used
Variable End-Stop Tuning
Dial in the exact retract distance between 350 and 450 mm during machine setup to accommodate different material lengths without adding external stops.
Product Changeover
Quickly adjust the stroke window on packaging lines when switching between box sizes, leveraging the 100 mm trim range to minimize downtime.
Sensor-Driven Positioning
Utilize the integrated magnet with DMSE electronic sensors to confirm end-of-stroke positions accurately while the rear screw sets the physical stop.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX450-100S the Right Cylinder?
Choose this 80 mm bore cylinder when an application requires trimming the retract end-position during commissioning or product changeover without swapping out the physical actuator. Because the 450 mm stroke is substantial, an external guide is recommended to prevent excessive side-loading on the 25 mm rod.
To match this exact ISO 15552 interchangeable replacement, specify: 80 mm bore, 450 mm stroke, 100 mm adjustment range, PT tapered port threads, a SUS420J2 rod, and the -S magnet option. Remember that the rear screw stopper and the variable air cushions only decelerate the load; for true load-holding without live air pressure, consider an AirTAC SAIL or BSAI cylinder. Mounting options are limited to Basic, FA, LB, TC, FTC, TCM1, and TCM2.
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 SAIJ80 Adjustable Cylinder SAIJ80AX450-100S FAQ
At a maximum 1.0 MPa pressure, it can deliver up to 513 kgf.
The rear adjuster screw allows you to shorten the effective stroke by up to 100 mm from the nominal 450 mm, giving an adjustable travel window of 350-450 mm. This stopper only sets the end position and does not lock the load without continuous air pressure.
