About the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX230-75
The AirTAC SAIJ80X230-75 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to fine-tune the effective travel down from a 230 mm nominal stroke to a 155 mm minimum. This creates a 75 mm variable end-stop window, ideal for dialing in exact retract positions during machine commissioning or product changeovers without swapping out hardware.
This SKU features a SUS304 stainless steel rod for superior corrosion resistance and includes PT tapered port threads (G3/8) for tight pneumatic sealing. The extruded aluminum barrel includes sensor grooves on both sides for direct mounting of CMSE reed or DMSE electronic switches. The rear adjustment screw acts purely as a mechanical travel stop and does not hold the load without live air pressure; for fail-safe load holding, consider the SAIL or BSAI series.

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 SAIJ80BX230-75 Is Used
Machine Setup Changeover
Leverage the 75 mm adjustment range to quickly reconfigure retract distances during product size changes on a packaging line without disassembling the cylinder.
End-Position Tuning
Dial in the exact 155 to 230 mm retract stop during initial commissioning to perfect pick-and-place coordinates without adding external physical stops.
Variable Stroke Pressing
Set the precise depth for pressing or clamping operations on the fly, accommodating different material thicknesses using the built-in rear stopper.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX230-75 the Right Cylinder?
Choose this 80 mm bore adjustable-stroke model when your application requires precise positioning within a 155-230 mm travel window. The SAIJ80X230-75 is dimensionally interchangeable per ISO 15552 and supports a reduced mounting set including Basic, FA, LB, TC, FTC, TCM1, and TCM2 (omitting FB, CA, CB, and CR). Because the nominal stroke is 230 mm, external guide rails should be used to support the load and mitigate side-load stress on the rod.

- ✓ 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 SAIJ80BX230-75 FAQ
At 0.7 MPa, the push force increases to 3518 N.
The rear adjuster acts as a mechanical stop that lets you shorten the effective stroke from its 230 mm nominal length down to 155 mm. This provides a 75 mm tuning window for precise end-positioning during setup.
