About the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX230-20
The AirTAC SAIJ80X230-20 is a double-acting ISO 15552 profile cylinder equipped with a rear mechanical stopper, allowing you to dial back the nominal 230 mm stroke by up to 20 mm for a usable 210-230 mm travel window. The 25 mm stainless SUS304 rod provides high corrosion resistance and handles side loads well.
This adjustable-stroke design eliminates the need to swap cylinders or bolt on external stops during product changeovers. It uses a PT tapered G3/8 port and retains the standard extruded aluminum barrel with dual-side sensor grooves. The rear adjuster acts purely as a travel stop and does not hold 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 SAIJ80BX230-20 Is Used
Product Changeovers
Quickly fine-tune the 210-230 mm travel end-stop during packaging line format changes without replacing the cylinder.
Variable End Stops
Adjust the retraction point on the fly to handle varying package sizes on a sorting conveyor system.
Machine Setup
Dial in the exact 80 mm bore thrust and end position during initial equipment commissioning.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX230-20 the Right Cylinder?
The 210-230 mm adjustable window is ideal for fine-tuning end positions at commissioning without adding external stops, unlike a fixed-stroke SAI cylinder. If your process demands true load-holding without live air, select a SAIL or BSAI cylinder instead.
To match this ISO 15552 footprint exactly, specify an 80 mm bore, 230 mm nominal stroke, 20 mm adjustment, PT G3/8 port, and Basic, FA, LB, TC, FTC, TCM1, or TCM2 mounting. Because the stroke is 230 mm, ensure an external guide supports any unsupported load to prevent rod side-loading.
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 SAIJ80BX230-20 FAQ
A rear stopper screw lets you shorten the effective travel from the 230 mm nominal stroke by up to 20 mm, creating a 210-230 mm adjustable window. This stopper sets the travel end but does not lock or hold the load without live air pressure.
At 0.9 MPa, the push force increases to 4523 N.
