About the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX230-75
The AirTAC SAIJ80X230-75 is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, allowing you to dial back the nominal 230 mm travel by up to 75 mm. This creates a highly flexible 155-230 mm usable positioning window, perfect for dialing in exact end-of-stroke locations during commissioning without needing external stops.
This model features PT tapered port threads and a 25 mm rod diameter that handles side loads well, though the 230 mm stroke still benefits from an external guide for optimal longevity. The extruded aluminum barrel includes sensor grooves on both sides, ready for CMSE or DMSE switches if a magnet is specified later. Mounting options include 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 SAIJ80AX230-75 Is Used
Product Changeovers
Quickly adapt machinery for varying package sizes by dialing the retract stroke back within the 155-230 mm window, avoiding physical cylinder swaps.
End-Position Tuning
Fine-tune the exact end-of-stroke stopping point during machine commissioning to perfect alignment without adding bulky external mechanical stops.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX230-75 the Right Cylinder?
The 75 mm adjustment range is ideal for product-size changeovers on a line, letting operators fine-tune the retract end position on the fly instead of swapping out a fixed-stroke SAI cylinder. For an exact ISO 15552 replacement, match the 80 mm bore, 230 mm stroke, PT ports, and the chosen mounting hardware.
Because the 230 mm stroke is significant, ensure an external guide supports the load to prevent excessive wear on the rod seals. Remember that the rear adjuster acts only as a travel stop and does not hold the load without live air; for true position holding without pneumatic pressure, consider an external rod lock or the AirTAC SAIL locking cylinder.

- ✓ 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 SAIJ80AX230-75 FAQ
At 0.7 MPa, the push force increases to 3518 N.
The rear adjuster screw acts as a mechanical stop that lets you shorten the effective stroke from its 230 mm nominal length down to as little as 155 mm. It sets the travel end and relies on the air cushion for deceleration, but it does not lock the load without live air pressure.
