About the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX145-100
The AirTAC SAIJ80X145-100 is a double-acting, double-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. This wide tuning capacity is ideal for machinery that frequently processes different product sizes.
Built with a SUS304 stainless steel rod for superior corrosion resistance and an M20x1.5 rod thread, this 80mm bore profile cylinder handles robust loads. It uses PT tapered ports and includes adjustable air cushions at both ends to decelerate moving masses smoothly. The rear stopper sets the end position, but it does not lock the load without continuous 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 SAIJ80BX145-100 Is Used
Variable End-Stop Positioning
Dial in the exact retract distance within the 45-145mm window during machine commissioning to accommodate new part dimensions without machining new hard stops.
Product Size Changeovers
Rapidly reconfigure packaging or handling lines for different product lengths by turning the rear adjuster screw, reducing downtime between production runs.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX145-100 the Right Cylinder?
The SAIJ80X145-100 is selected over a fixed-stroke SAI cylinder when you need on-the-fly commissioning adjustments without swapping hardware.
Because the nominal stroke is 145mm, side-load stress is moderate, but the 25mm rod diameter provides excellent rigidity. For load-holding without live air pressure, this cylinder is insufficient since the rear adjuster acts only as a travel stop; you should specify an AirTAC SAIL or BSAI locking cylinder instead. To match this ISO 15552 interchangeable unit, confirm an 80mm bore, 145mm stroke, 100mm adjuster, PT port thread, SUS304 rod, and no magnet.
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 SAIJ80BX145-100 FAQ
At a maximum 1.0 MPa operating pressure, it can deliver up to 513 kgf.
The rear adjuster screw acts as a mechanical stop, allowing you to shorten the 145mm nominal stroke by up to 100mm. This creates a usable travel window of 45-145mm, enabling fine-tuning of the retract end position without replacing the cylinder.
