About the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX230-30S
The AirTAC SAIJ80X230-30-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to fine-tune the effective travel within a 200 to 230 mm window. Equipped with a SUS304 stainless steel rod, it provides excellent corrosion resistance for demanding environments.
Because the adjuster acts solely as a mechanical stop at the retract end, it cannot hold a load without live air pressure. The extruded aluminum barrel includes sensor grooves on both sides, and the integrated -S magnet works seamlessly with AirTAC CMSE reed and DMSE solid-state switches for precise position feedback. You can fine-tune end positions at commissioning without swapping out the physical cylinder or adding external stops.

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 SAIJ80BX230-30S Is Used
Product Changeover
Dial in the 30 mm stroke adjustment during format changes on packaging lines to accommodate different carton or part sizes without swapping cylinders.
End-Position Tuning
Fine-tune the retract stop during machine commissioning to perfectly time the 200-230 mm travel window without adding external mechanical stops.
Corrosive Actuation
Leverage the SUS304 stainless steel rod for heavy-duty clamping or material handling tasks in washdown or mildly corrosive industrial environments.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX230-30S the Right Cylinder?
The 30 mm adjustment range is ideal for product changeovers on a production line, allowing you to dial in the exact end-stop position without mechanical modifications. For load-holding requirements without continuous air pressure, consider the SAIL or BSAI series instead, as the SAIJ adjuster is not a locking mechanism.
When integrating this cylinder, note the PT tapered port thread type and the G3/8 air supply connection. The SAIJ series supports a specific mounting subset including Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting the FB, CA, CB, and CR options found on other variants. With a 230 mm stroke, the 25 mm rod diameter and M20x1.5 rod thread provide substantial rigidity, but an external guide is still recommended to manage side-load forces on the piston rod.
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 SAIJ80BX230-30S FAQ
At the maximum 1.0 MPa pressure, it can deliver up to 513 kgf.
The rear adjuster screw acts as a mechanical stop that shortens the nominal 230 mm stroke by up to 30 mm, providing a usable travel window of 200 to 230 mm. It only sets the retract end position and does not lock or hold the load without continuous air pressure.
