About the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX230-30
The AirTAC SAIJ80X230-30 is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a usable travel window of 200 to 230 mm, allowing you to dial in the exact retract end-position during commissioning without adding external stops. In the 80 mm bore class, it delivers a robust 2268 N pull force at 0.5 MPa, making it well-suited for heavy positioning tasks.
This model uses a SUS304 stainless steel rod for superior corrosion resistance and ships with PT tapered port threads. The extruded aluminum barrel includes sensor grooves on both sides for flexible switch placement. It supports a speed range of 30-800 mm/s and utilizes a 25 mm rod with an M20x1.5 thread to handle high side loads effectively.

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 SAIJ80BX230-30 Is Used
Variable End-Stop Positioning
Dial the retract stroke back by up to 30 mm to hit a precise end-position on demand without physically remounting the cylinder or adding external collars.
Product Changeover
Quickly adapt a packaging or handling line to new product sizes by turning the rear adjuster to shift the 200-230 mm travel window as needed.
Commissioning Fine-Tuning
Perfectly time the machine sequence during setup by trimming the stroke in tiny increments, avoiding the cost and delay of ordering a custom-length cylinder.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX230-30 the Right Cylinder?
Choose this 80 mm bore when your application requires more force than the 63 mm class (1402 N pull at 0.5 MPa) but does not warrant the larger 100 mm size. The adjustable stroke is ideal for product changeovers on a line, letting you fine-tune the end-stop on the fly instead of swapping out a fixed-stroke SAI cylinder. For strokes of 230 mm or more, always use an external guide to prevent rod side-loading and premature seal wear.
When specifying an ISO 15552 replacement, match the 80 mm bore, 230 mm nominal stroke, 30 mm adjustment range, PT port threads, and your required mounting bracket from the SAIJ set (Basic, FA, LB, TC, FTC, TCM1, TCM2). Remember that the rear adjuster acts only as a travel stop; it does not hold the load without live air. For true load-holding, consider an external rod lock or the AirTAC SAIL/BSAI series.
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 SAIJ80BX230-30 FAQ
The rear adjuster screw lets you shorten the effective stroke by up to 30 mm. This creates a usable travel window between 200 and 230 mm, allowing you to set the exact retract end-position without replacing the cylinder.
