Airtac SAIJ80 Adjustable Cylinder SAIJ80BX130-75S
The AirTAC SAIJ80 Adjustable Cylinder SAIJ80BX130-75S 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 SAIJ80BX130-75S
It features a SUS304 stainless steel rod and a built-in magnet for position sensing. By turning the rear stopper screw, you can trim the effective travel anywhere within a 55 to 130 mm window without swapping hardware.
This wide 75 mm adjustment band is ideal for product changeovers on packaging lines. The cylinder uses a G3/8 port and relies on standard variable air cushions at both ends to decelerate the load. Note that the rear stopper sets the end position but does not lock the load 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 SAIJ80BX130-75S Is Used
Variable End-Stop Positioning
Dial in the exact retraction point between 55 and 130 mm during machine setup to accommodate different material thicknesses without changing the cylinder.
Packaging Line Changeover
Quickly alter the stroke length on a packaging conveyor when switching to a new carton size, using the rear screw to fine-tune the push distance.
Sensor-Driven Assembly
Leverage the integrated magnet with CMSE reed or DMSE electronic switches to confirm rod position in automated assembly presses.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX130-75S the Right Cylinder?
Choose this 80 mm bore when an application requires roughly 2268N of pull force at 0.5 MPa, stepping up from a 63 mm bore that provides 1402N. The extensive 75 mm adjustment range allows precise end-position tuning during commissioning, replacing the need to bolt on external stops or order multiple fixed-stroke SAI cylinders. To match this ISO 15552 footprint exactly, specify an 80 mm bore, 130 mm stroke, PT port threads, and the -S magnet option.
Because the stroke is 130 mm, side loading is moderate, but the 25 mm rod diameter handles standard loads well. For load-holding without continuous air pressure, integrate an external pilot-operated check valve or select the AirTAC SAIL or BSAI locking cylinder series instead of relying on the adjuster.
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 SAIJ80BX130-75S FAQ
The rear stopper screw allows you to shorten the effective stroke by up to 75 mm. This creates a usable travel window of 55 to 130 mm, letting you fine-tune the end position at commissioning without external stops.
