Airtac SAIJ80 Adjustable Cylinder SAIJ80AX130-40
The AirTAC SAIJ80 Adjustable Cylinder SAIJ80AX130-40 is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø80mm bore and 130mm stroke, G3/8 air ports and adjustable end cushioning. Its standardized mounting interface makes it interchangeable with other ISO 15552 cylinders at the mounting interface.

About the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX130-40
The AirTAC SAIJ80X130-40 is a double-acting, double-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It provides a 90 to 130 mm usable travel window, allowing you to dial back the nominal 130 mm stroke by up to 40 mm during commissioning.
This variant features an SUS420J2 stainless steel rod (material code A) for enhanced corrosion resistance and a PT tapered port thread. The extruded aluminum barrel includes sensor grooves on both sides, ready to accept CMSE reed or DMSE electronic switches if a magnet is added later. The rear adjuster acts purely as a mechanical stop to set the end position, meaning it will not hold the load safely 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 SAIJ80AX130-40 Is Used
Product Changeovers
Dial in the 90 to 130 mm retract window on the fly to accommodate different carton depths without changing out tooling.
End-Stop Tuning
Fine-tune the exact bottoming position during machine commissioning to prevent crushing delicate workpieces.
Variable Diverter Stroke
Adjust the actuator reach on a sorting line to handle varying package widths while maintaining a standard ISO 15552 footprint.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX130-40 the Right Cylinder?
The 40 mm adjustment range is ideal for product-size changeovers on a packaging line, letting operators fine-tune the retract end position without swapping out the cylinder or adding external stop blocks. For load-holding without continuous air pressure, an external rod lock or a related AirTAC type like SAIL or BSAI is required.
When matching this for an ISO 15552 replacement, verify the 130 mm stroke, the 40 mm adjuster, G3/8 port, and the reduced SAIJ mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2). Because the stroke is 130 mm, the 25 mm rod and M20x1.5 thread provide robust side-load capacity, though any long unsupported overhang should still utilize an external guide rail.
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 SAIJ80AX130-40 FAQ
At 0.7 MPa, the push force increases to 3518 N.
The rear adjuster screw lets you mechanically shorten the effective stroke from its 130 mm nominal length down to a minimum of 90 mm. It functions as a travel stop for end-position tuning and does not lock the load without air pressure.
