About the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX130-20
The AirTAC SAIJ80X130-20 is a double-acting, double-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It provides a usable travel window of 110 to 130 mm, enabling precise end-position tuning at commissioning without external stops.
This unit features a SUS304 stainless steel rod for superior corrosion resistance and a PT tapered port thread (G3/8). The extruded aluminum barrel includes sensor grooves on both sides for flexible CMSE or DMSE switch mounting. The rear adjuster acts purely as a travel stop to set deceleration, not as a lock to hold the load without live air.

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 SAIJ80BX130-20 Is Used
Machine Changeover
Dial in the exact 110-130 mm end-stop during product size changes without swapping the cylinder or adding shims.
Variable Diverters
Fine-tune the retract position of a diverter arm on the fly to accommodate different package widths on the line.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX130-20 the Right Cylinder?
Choose this 80 mm bore when your application requires substantial thrust—stepping up from a 63 mm bore yields 1559 N at 0.5 MPa, while dropping to a 50 mm bore reduces force to 982 N. The 20 mm adjustment range is ideal for variable end-stops during machine changeover, offering a setup advantage over a fixed-stroke SAI cylinder. If your process needs to hold a load vertically without continuous air pressure, select a SAIL or BSAI cylinder instead, as the SAIJ adjuster cannot lock the load. To match this ISO 15552 footprint exactly, specify an 80 mm bore, 130 mm stroke, 20 mm adjustment, PT G3/8 ports, and Basic, FA, LB, TC, FTC, TCM1, or TCM2 mounts. For this 130 mm stroke, ensure external guides support the load to prevent rod side-loading.

- ✓ 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 SAIJ80BX130-20 FAQ
At 0.9 MPa, the push force increases to 4523 N.
The rear adjuster screw shortens the effective travel from the nominal 130 mm down to 110 mm. It functions as a mechanical stop to set the end position and does not lock or hold the load without live air pressure.
