About the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX150-30S
The AirTAC SAIJ80X150-30-S is a double-acting, double-rod ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. The built-in stopper screw provides up to 30mm of travel reduction, creating a precise 120-150mm usable stroke window for fine-tuning end positions during machine commissioning.
This variant includes a SUS304 stainless steel rod for superior corrosion resistance and is equipped with a magnet for position sensing. It integrates seamlessly with AirTAC CMSE reed and DMSE solid-state switches via the dual sensor grooves on the extruded aluminum barrel. The rear adjuster acts purely as a mechanical stop to set the retract position and does not hold the load without live air pressure.

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 SAIJ80BX150-30S Is Used
Machine Changeover Tuning
Dial in the 120-150mm stroke window during product size changeovers to set new retract stops without replacing the cylinder or adding external physical stops to the machine frame.
End-Position Calibration
Fine-tune the exact end-of-stroke position during initial commissioning to compensate for mechanical tolerance stack-up in your tooling and fixturing.
Variable Assembly Stops
Adjust the travel end-point on the fly for assembly lines handling multiple product variants, ensuring precise clamping without overtravel.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX150-30S the Right Cylinder?
Select this 80mm bore cylinder when an application requires substantial thrust paired with on-the-fly end-position tuning, avoiding the need to physically swap cylinders or bolt on external stops during product changeovers. For applications needing true load-holding without continuous air pressure, consider the SAIL air-released lock or BSAI clamp-lock cylinders instead of relying on the SAIJ adjuster.
This SAIJ80X150-30-S configuration features a PT tapered port thread, a standard 150mm stroke, and a 30mm adjustment range. It supports a speed range of 30-800mm/s and accepts the reduced SAIJ mounting set including Basic, FA, LB, TC, FTC, TCM1, and TCM2. Dimensionally interchangeable per ISO 15552, it provides a direct replacement match when you specify the 80mm bore, 150mm stroke, PT port, and -S magnet option.

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 SAIJ80BX150-30S FAQ
At 0.7MPa, the push force increases to 3518N. The standard speed range for this bore size is 30-800mm/s.
The rear adjuster screw acts as a mechanical stop that allows you to shorten the nominal 150mm stroke by up to 30mm, resulting in a usable travel window of 120-150mm. This mechanism only sets the travel end-point and does not lock or hold the load without live air pressure.
