About the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX230-50
The AirTAC SAIJ80X230-50 is a double-acting, double-rod ISO 15552 profile cylinder featuring a rear stroke adjuster. The integrated rear stopper allows you to trim the effective travel within a 180-230mm window, providing exact end-position tuning during commissioning without swapping out the entire actuator.
This specific configuration includes a SUS304 stainless steel rod for superior corrosion resistance and utilizes PT tapered port threads. The extruded aluminum barrel incorporates sensor grooves on both sides. While the rear adjuster sets the travel limit, remember it acts as a stop and not a lock; the cylinder cannot hold a load without live air pressure.

Specifications follow the official AirTAC SAI series datasheet and ISO 15552 dimensions. Confirm against the product label before installation. Port options: G (BSPP) / NPT.
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 SAIJ80BX230-50 Is Used
Product Changeover
Quickly adjust the 180-230mm travel window during format changeovers on packaging lines to accommodate different carton sizes without changing cylinders.
End-Position Tuning
Fine-tune the retract end-stop precisely during machine commissioning to dial in exact clamping or positioning without external mechanical stops.
Variable End Stops
Ideal for automated assembly stations where the rear 50mm adjuster sets different stroke endpoints for multiple distinct operations on a single line.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX230-50 the Right Cylinder?
The 50mm adjustment range is ideal for machines processing varying product sizes, allowing operators to dial in the exact 180-230mm end-stop on the fly instead of adding external stops. For load-holding without continuous air pressure, consider the SAIL or BSAI series instead.
When replacing an ISO 15552 cylinder, match the 80mm bore, 230mm stroke, 50mm adjustment, PT port thread, and standard mounting options (Basic, FA, LB, TC, FTC, TCM1, TCM2). Because the 230mm stroke is substantial, the 25mm rod diameter handles side loads well, but an external guide is still recommended for unsupported loads to prevent premature wear.
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 SAIJ80BX230-50 FAQ
At 0.7MPa, the push force increases to 3518N.
The rear adjuster acts as a mechanical stop that allows you to shorten the nominal 230mm stroke by up to 50mm, creating a usable travel window of 180-230mm. It sets the end position but does not lock the load without live air pressure.
