Airtac SAIJ80 Adjustable Cylinder SAIJ80BX230-50S
The AirTAC SAIJ80 Adjustable Cylinder SAIJ80BX230-50S is a genuine double-acting ISO 15552 profile-barrel air cylinder with a Ø80mm bore and 230mm stroke, G3/8 air ports and adjustable end cushioning. Its standardized mounting interface makes it interchangeable with other ISO 15552 cylinders at the mounting interface.

About the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX230-50S
The AirTAC SAIJ80X230-50-S is a double-acting, double-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It provides a nominal 230 mm stroke that can be fine-tuned backward by up to 50 mm, yielding a practical usable travel window of 180-230 mm.
This specific configuration includes a SUS304 stainless steel rod (code B) for superior corrosion resistance and features a built-in magnet (-S) for position sensing. The extruded aluminum barrel integrates sensor grooves on both sides, directly supporting AirTAC CMSE reed and DMSE electronic solid-state switches. The rear adjuster acts strictly as a mechanical stop to set the retraction end position during commissioning; it does not lock or hold the load without continuous 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 SAIJ80BX230-50S Is Used
Product Changeover
Dial in the 180-230 mm travel window during format changes on packaging lines without swapping out the entire actuator.
End-Position Tuning
Fine-tune the retract end-stop during machine commissioning to perfectly seat parts without adding external mechanical shims.
Variable Stops
Adjust the rejection stroke on a conveyor system on the fly to accommodate different package depths.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX230-50S the Right Cylinder?
Select this 80 mm bore cylinder when an application requires high push force (2513 N at 0.5 MPa) alongside variable end-stop positioning. If you need less force, stepping down to a 63 mm bore yields 1559 N, whereas moving up to a 100 mm bore provides 3927 N. The adjustable stroke is ideal for machine setups requiring frequent product changeovers, eliminating the need to physically swap cylinders or add external shims. For load-holding without live air pressure, this cylinder is insufficient; you must integrate an external pilot-operated check valve or select an AirTAC SAIL or BSAI locking cylinder.
To replace an ISO 15552 cylinder, match the 80 mm bore, 230 mm nominal stroke, 50 mm adjustment range, PT tapered port threads, and the -S magnet option. Mounting choices are restricted to the SAIJ subset: Basic, FA, LB, TC, FTC, TCM1, and TCM2. Because the 230 mm stroke is moderately long, ensure external guide rails are used to support the load and prevent excessive side-loading on the 25 mm rod and M20x1.5 rod thread.

- ✓ 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 SAIJ80BX230-50S FAQ
At a maximum 1.0 MPa, it can deliver up to 513 kgf.
The rear adjusting screw acts as a mechanical stop, allowing you to trim the effective stroke back from the 230 mm nominal length by up to 50 mm, creating a 180-230 mm usable travel window. It only sets the end position and does not lock the load.
