About the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX145-75S
It features a SUS304 stainless steel rod and a PT tapered port thread. The integrated -S magnet enables seamless position detection with AirTAC CMSE reed and DMSE electronic sensors.
With a 145mm nominal stroke and a 75mm adjustment code, this model provides a wide usable travel window of 70 to 145mm. This allows exact end-position tuning during commissioning without swapping hardware. The extruded aluminum barrel includes sensor grooves on both sides, and the mounting options cover Basic, FA, LB, TC, FTC, TCM1, and TCM2.

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 SAIJ80BX145-75S Is Used
Product Changeovers
Dial in the exact end-stop during format size changes on a packaging line, utilizing the 70-145mm travel window to accommodate varying package dimensions without mechanical rebuilds.
Machine Setup Calibration
Fine-tune the retract position during initial commissioning to precisely set the pressing force, leveraging the 25mm SUS304 rod for durable and repeatable contact.
Variable End Stops
Implement flexible material handling stops where the required retraction distance frequently changes, relying on the 2513N pull force at 0.5 MPa to move the load reliably.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX145-75S the Right Cylinder?
The 75mm adjustment range is ideal for product-size changeovers on a line, letting you dial back the travel from 145mm down to 70mm. If your application requires holding a load without live air pressure, note that this rear adjuster acts only as a travel stop, not a lock; you would need an external rod lock or a SAIL pneumatic lock cylinder instead.
Because the 145mm stroke is under the 300mm threshold, side-load risks are moderate, but the 25mm rod diameter and M20x1.5 rod thread still provide excellent rigidity. For exact ISO 15552 replacement matching, verify the 80mm bore, 145mm stroke, 75mm adjustment, G3/8 port, PT thread, and the -S magnet requirement.
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 SAIJ80BX145-75S FAQ
The rear adjuster screw acts as a mechanical stop that lets you shorten the effective travel from the 145mm nominal stroke down to as little as 70mm, providing a 75mm adjustment window. This allows you to fine-tune the end position at commissioning without adding external stops.
It operates at speeds between 30 and 800 mm/s and uses a G3/8 port.
