About the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX130-40
The AirTAC SAIJ80X130-40 is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a nominal 130 mm stroke that can be fine-tuned down by up to 40 mm, yielding a usable travel window of 90 to 130 mm. The extruded aluminum barrel includes sensor grooves on both sides for flexible switch placement.
This SKU is configured with a SUS304 stainless steel rod for superior corrosion resistance and a PT tapered port thread. The 25 mm rod diameter and M20x1.5 rod thread provide excellent side-load capacity, though external guides are still recommended for offset loads. The rear adjuster acts purely as a mechanical stop to set the end position and does not lock the load without continuous 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 SAIJ80BX130-40 Is Used
Product Changeover
Dial in the 90 to 130 mm travel window during packaging line format changes to accommodate varying carton sizes without mechanical rebuilds.
Variable Assembly Stops
Adjust the mechanical stop on the fly for assembly stations handling multiple part lengths, relying on the robust 25 mm SUS304 rod.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX130-40 the Right Cylinder?
Select this 80 mm bore when an application requires substantial force, stepping up from a 63 mm bore that provides 1559 N at 0.5 MPa. The 40 mm adjustment range is ideal for product changeovers, allowing operators to dial in the exact end-stop without swapping cylinders or adding external stops. For fixed-position tasks, a standard SAI cylinder suffices, but the SAIJ variant excels in flexible setups.
When matching ISO 15552 replacements, verify the 130 mm stroke, 40 mm adjuster, PT port thread, and SUS304 rod material. Note that SAIJ supports a reduced mounting set of Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR. Because the stroke is 130 mm, side-load risks are moderate, but ensuring proper external guiding will maximize seal life.

- ✓ 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 SAIJ80BX130-40 FAQ
At 0.7 MPa, the push force increases to 3518 N.
The rear adjuster acts as a mechanical stop that shortens the effective travel. For this 130 mm stroke model, you can trim the retract distance by up to 40 mm, creating a usable travel window of 90 to 130 mm. It does not lock the load without live air pressure.
