About the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX240-30
The AirTAC SAIJ80X240-30 is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. This eliminates the need to swap cylinders during product changeovers.
Equipped with a SUS304 stainless steel rod for superior corrosion resistance, this model uses a PT G3/8 port and variable air cushions at both ends. The rear screw acts purely as a travel stop for deceleration and does not hold the load without live air pressure. For load-holding requirements, consider the SAIL or BSAI series instead.

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 SAIJ80BX240-30 Is Used
Product Changeover
Dial in the 210-240mm travel window during packaging line format changes to accommodate different carton sizes without swapping hardware.
End-Stop Calibration
Fine-tune the final retract position during machine commissioning to prevent mechanical crashes, using the rear screw rather than external shims.
Variable Positioning
Adjust the stroke endpoint on automated assembly presses where multiple seating depths are required for different workpiece variants.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX240-30 the Right Cylinder?
If your setup needs less force, stepping down to a 63mm bore yields 1559N. To match this ISO 15552 footprint exactly, specify the 80mm bore, 240mm stroke, 30mm adjustment, PT G3/8 port, and SUS304 (B) rod material.
Since the 240mm stroke is under the 300mm threshold, side-load risks are moderate, but the robust 25mm rod and M20x1.5 thread handle standard loads well. Mounting options include Basic, FA, LB, TC, FTC, TCM1, and TCM2, deliberately omitting FB, CA, CB, and CR styles.
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 SAIJ80BX240-30 FAQ
At the maximum 1.0 MPa pressure, it can deliver up to 513 kgf.
The rear adjuster screw lets you shorten the 240mm nominal stroke by up to 30mm, yielding a 210-240mm travel window. It acts as a mechanical stop to set the end position and does not lock the load without continuous air pressure.
