About the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX270-10
The AirTAC SAIJ80X270-10 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that creates a 260-270 mm usable travel window. The extruded aluminum barrel includes sensor grooves on both sides for flexible switch placement.
This model uses a SUS304 stainless steel rod for superior corrosion resistance and features PT tapered port threads. The rear adjuster acts as a mechanical stop to fine-tune the retract end position during commissioning without adding external stops. It is not a locking device and requires live air to hold a 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 SAIJ80BX270-10 Is Used
Machine Changeover
Quickly fine-tune the 260-270 mm retract position during product size changes without swapping the cylinder or bolting on external stops.
End-Position Tuning
Dial in the exact end-of-stroke stop during commissioning to compensate for mechanical tolerance stack-ups in your fixture.
Variable End Stops
Set a precise retract distance for operations requiring a slightly shorter stroke than the 270 mm nominal length.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX270-10 the Right Cylinder?
Choose this 80 mm bore cylinder when you need more force than the 63 mm bore (1559 N at 0.5 MPa) but less than the 100 mm bore (3927 N). The 10 mm adjustment range is perfect for dialing in exact end positions during product changeovers on a line. For load-holding without live air pressure, select the SAIL or BSAI series instead, as the SAIJ adjuster only sets the travel end.
When replacing an ISO 15552 cylinder, match the 80 mm bore, 270 mm stroke, 10 mm adjustment, G3/8 PT port, and Basic, FA, LB, TC, FTC, TCM1, or TCM2 mounting. Because the 270 mm stroke is relatively long, ensure an external guide supports the load to prevent excessive side loading on the 25 mm rod.
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 SAIJ80BX270-10 FAQ
The rear adjuster screw lets you shorten the 270 mm nominal stroke by up to 10 mm, creating a 260-270 mm travel window. It acts as a mechanical stop to fine-tune the end position and does not lock the load without live air.
