About the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX145-30
The AirTAC SAIJ80X145-30 is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, providing a usable travel window of 115-145 mm for precise end-position tuning. The extruded aluminum barrel features sensor grooves on both sides for flexible switch placement.
This variant features an SUS420J2 stainless steel rod (material code A) for enhanced corrosion resistance and utilizes PT tapered port threads with a G3/8 connection. The rear adjustment screw acts purely as a travel stop to dial in the 30 mm trim range during commissioning; it does not lock the load without continuous air pressure. For load-holding requirements, an external pilot-operated check valve or a related SAIL lock cylinder is required.

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 SAIJ80AX145-30 Is Used
Product Changeover
Dial in the 115-145 mm travel window during format size changes on packaging lines without replacing the cylinder or adding shims.
Machine Setup
Fine-tune the retract end-position at commissioning using the rear stopper to achieve exact tooling alignment on heavy machinery.
Variable End Stops
Adjust the stroke dynamically for diverter gates that need to accommodate different package sizes on a single conveyor belt.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX145-30 the Right Cylinder?
The adjustable 115-145 mm travel window is ideal for production lines requiring frequent product-size changeovers, allowing you to fine-tune the retract position without swapping cylinders or adding external stops. If your machinery needs to hold a load without live air, remember that the SAIJ adjuster is only a stop—you must integrate an external rod lock or choose a BSAI clamp-lock cylinder.
When replacing an ISO 15552 cylinder, match the 80 mm bore, 145 mm stroke, 30 mm adjustment, G3/8 PT ports, and your required mounting style. The SAIJ series supports a reduced mounting set including Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR options. Because the 25 mm rod and M20x1.5 thread handle high side loads, ensure your mounting configuration provides adequate external guidance for the 145 mm stroke.
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 SAIJ80AX145-30 FAQ
At 0.7 MPa, the push force increases to 3518 N.
The rear adjuster screw allows you to trim the nominal 145 mm stroke back by up to 30 mm, creating a usable travel window of 115-145 mm. This stopper sets the end position but does not lock the load without live air pressure.
