Airtac SAIJ80 Adjustable Cylinder SAIJ80BX145-100S
The AirTAC SAIJ80 Adjustable Cylinder SAIJ80BX145-100S is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø80mm bore and 145mm 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 SAIJ80BX145-100S
Its generous 100mm adjustment range creates a highly flexible 45-145mm usable travel window, allowing precise end-position tuning during commissioning without swapping hardware. The SUS304 stainless steel rod provides superior corrosion resistance, while the integrated magnet supports CMSE reed and DMSE electronic sensors for exact position feedback.
This model features PT tapered ports and a 25mm rod with an M20x1.5 thread, yielding robust side-load capacity for dynamic applications. It shares the standard extruded aluminum barrel and dual-side sensor grooves of the SAI series, but utilizes a reduced mounting subset of Basic, FA, LB, TC, FTC, TCM1, and TCM2. The rear screw functions purely as a travel stop to set deceleration, not as a lock, meaning live air is required to maintain the load position.

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 SAIJ80BX145-100S Is Used
Variable End-Stop Calibration
Dial in the exact 45 to 145mm retract position during machine setup to accommodate different material thicknesses without adding external mechanical stops.
Product Changeover Systems
Rapidly reconfigure sorting gates and pushing distances on a packaging line by adjusting the rear screw rather than replacing the entire cylinder.
Sensor-Driven Positioning
Leverage the integrated magnet with DMSE electronic sensors to verify the adjusted end position in automated assembly processes.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX145-100S the Right Cylinder?
Select this 80mm bore when an application demands high thrust combined with extreme setup flexibility, such as accommodating multiple product sizes on a single line. Conversely, if you need more power, a 100mm bore provides 3927N. The 100mm adjustment window is ideal for variable end-stops, replacing the need to inventory multiple fixed-stroke SAI cylinders.
For an exact ISO 15552 replacement, match the 80mm bore, 145mm nominal stroke, 100mm adjuster, PT ports, and the -S magnet. Because the nominal stroke is 145mm, the 25mm rod handles side loads adequately, though any long unsupported travel still requires an external guide. Remember that the adjuster only trims the retract end; for true load-holding without live air pressure, consider an AirTAC SAIL or BSAI cylinder.
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 SAIJ80BX145-100S FAQ
At 0.7 MPa, the push force increases to 3518N.
The rear adjuster screw allows you to trim the effective stroke by up to 100mm from the 145mm nominal length, creating a usable travel window of 45 to 145mm. This stopper sets the travel end and deceleration point but does not lock the load without continuous air pressure.
