About the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX150-30
The AirTAC SAIJ80X150-30 is a double-acting, double-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. By integrating a 30mm adjustment screw at the rear, this unit provides a usable travel window of 120 to 150mm, allowing you to dial in the exact retract end-position during commissioning without swapping out the hardware.
This specific configuration features an SUS420J2 stainless steel rod (material code A) for enhanced corrosion resistance, paired with PT tapered port threads and a G3/8 air connection. The extruded aluminum barrel incorporates sensor grooves on both sides, ready to accept AirTAC CMSE reed or DMSE electronic switches if a magnet is added later. It utilizes a reduced mounting subset of Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR options.

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 SAIJ80AX150-30 Is Used
Product Size Changeovers
Quickly fine-tune the 120 to 150mm retract distance when switching a packaging line to accommodate different carton or container depths without changing cylinders.
End-Stop Calibration
Dial in the exact clamping position during machine commissioning, using the 30mm rear adjuster to perfect the mechanical endpoint without adding external stopper blocks.
Variable Forming Depth
Control the stroke window on a press or forming station where the material displacement depth requires precise, on-the-fly mechanical tuning at the rear of the cylinder.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX150-30 the Right Cylinder?
The adjustable 120 to 150mm travel window is ideal for product changeovers on a line, where a fixed-stroke SAI cylinder would require mechanical spacers or a complete physical replacement to accommodate varying part sizes. The 25mm piston rod and M20x1.5 rod thread provide excellent structural rigidity and side-load tolerance.
Because the 150mm stroke is below the 300mm threshold, external guide requirements are less critical than on longer strokes, though the 25mm rod still handles substantial lateral stress. Remember that the rear adjuster functions strictly as a travel stop to set deceleration, not as a locking device; the cylinder cannot hold a load without live air pressure. For true load-holding, consider an AirTAC SAIL or BSAI cylinder. To match this ISO 15552 footprint exactly, specify an 80mm bore, 150mm stroke, 30mm adjustment, PT ports, and the desired mounting style.
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 SAIJ80AX150-30 FAQ
If pressure is increased to 0.9MPa, the push force reaches 4523N.
The rear adjusting screw acts as an external stopper that lets you shorten the effective stroke by up to 30mm. This creates a usable travel window of 120 to 150mm, allowing you to set the exact retract end-position during setup without replacing the cylinder.
