About the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX230-40
The AirTAC SAIJ80X230-40 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that lets you trim the effective travel by up to 40 mm. This creates a 190-230 mm usable window, allowing precise end-position tuning at commissioning without swapping the barrel or adding external stops. It delivers a robust 2513 N pull force at 0.5 MPa, making it suitable for heavy-duty positioning tasks.
The extruded aluminum barrel includes sensor grooves on both sides, and the piston rod uses an SUS420J2 stainless steel material for enhanced durability against minor moisture. Fluid is filtered air, operating pressure is 0.15-1.0 MPa, and the PT tapered port is G3/8. The rear adjuster acts purely as a mechanical stop to set the travel end; it 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 SAIJ80AX230-40 Is Used
Variable End-Stop Tuning
Dial in the exact 190-230 mm retract position during machine commissioning to accommodate different product thicknesses without machining new hard stops.
Product Size Changeover
Quickly adjust the stroke length on packaging or assembly lines when switching between product variants, reducing downtime between production runs.
Heavy-Duty Positioning
Leverage the 2513 N pull force to reliably shift heavy pallets or fixtures, using the rear screw to fine-tune the final resting position.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX230-40 the Right Cylinder?
The adjustable stroke is ideal for machine setups requiring variable end-stops during product changeovers. If you need to hold a load securely without continuous air pressure, this cylinder is not a lock; you should use an AirTAC SAIL or BSAI model instead.
This SAIJ unit is dimensionally interchangeable per ISO 15552. To match it exactly for a replacement, verify the 80 mm bore, 230 mm stroke, 40 mm adjustment, PT G3/8 port, and the specific mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2). Because the stroke is 230 mm, ensure adequate external guiding for long unsupported loads to prevent rod side-loading damage.
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 SAIJ80AX230-40 FAQ
At the maximum operating pressure of 1.0 MPa, the push force reaches 5026 N.
The rear adjuster screw acts as a mechanical stop that lets you shorten the 230 mm nominal stroke by up to 40 mm, providing a usable travel window of 190 to 230 mm. It only sets the end position and does not lock the load without air pressure.
