About the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX155-75
The AirTAC SAIJ80X155-75 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that permits an 80-155 mm usable travel window. The extruded aluminum barrel includes sensor grooves on both sides for flexible detection mounting.
This SKU is configured with a SUS304 stainless steel rod for superior corrosion resistance and features PT tapered port threads. The rear adjuster acts purely as a mechanical stop to fine-tune the retract end position during commissioning without adding external stops. It is not a locking device, so live air pressure is required to hold the load.

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 SAIJ80BX155-75 Is Used
Machine Changeover
Dial in the 80-155 mm travel window during product size transitions without replacing the cylinder or adding external stoppers.
End-Position Tuning
Fine-tune the retract stroke endpoint at commissioning to perfect machine timing and mechanical positioning.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX155-75 the Right Cylinder?
Choose this 80 mm bore when your application requires more thrust than a 63 mm cylinder (1559 N at 0.5 MPa) but less than a 100 mm unit (3927 N). The 75 mm adjustment range is ideal for product-size changeovers on a line, allowing the end-of-stroke position to be dialed in precisely without swapping the cylinder. Mounting options include Basic, FA, LB, TC, FTC, TCM1, and TCM2.
For load-holding without continuous air pressure, this cylinder is insufficient as the adjuster only decelerates the travel end; consider an AirTAC SAIL or BSAI series instead. The standard speed range is 30-800 mm/s.
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 SAIJ80BX155-75 FAQ
It can deliver up to 4523 N at 0.9 MPa.
The rear adjuster screw lets you shorten the 155 mm nominal stroke by up to 75 mm, creating an 80-155 mm usable travel window. It functions as a mechanical stop to set the end position, not as a lock to hold the load.
