About the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX280-10
The AirTAC SAIJ80X280-10 is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, allowing you to fine-tune the end position during commissioning.
Built with a SUS304 stainless steel rod for superior corrosion resistance, this 80mm bore actuator features PT tapered port threads (G3/8) and operates at speeds of 30-800mm/s. The extruded aluminum barrel includes sensor grooves on both sides, and while no magnet is installed, the groove readily accepts CMSE reed or DMSE solid-state switches when added. Mounting is limited to the SAIJ subset: 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 SAIJ80BX280-10 Is Used
Machine Setup Tuning
Dial in the exact end-stop position during initial commissioning without swapping out the entire cylinder or machining external spacers.
Product Changeover
Quickly adapt the 280mm stroke by up to 10mm to accommodate slightly different package sizes or part lengths running on the same line.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX280-10 the Right Cylinder?
The 10mm adjustment range is ideal for product changeovers where exact end-of-travel positioning varies slightly. Because the stroke is 280mm, you should use an external guide to prevent side-load damage to the rod and seals.
Remember that the rear adjuster acts purely as a travel stop and does not hold the load without live air pressure; for fail-safe load holding, consider the SAIL or BSAI series. As a dimensionally interchangeable ISO 15552 cylinder, you can directly match this replacement by specifying an 80mm bore, 280mm stroke, 10mm adjustment, PT G3/8 ports, and your preferred mounting bracket.
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 SAIJ80BX280-10 FAQ
The rear adjuster screw lets you shorten the effective travel from the nominal 280mm down to 270mm, creating a 270-280mm usable window. This stopper only sets the travel end and deceleration; it does not lock the load without continuous air pressure.
