About the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX270-10S
The AirTAC SAIJ80X270-10-S is a double-acting, double-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster.
This specific configuration includes a SUS304 stainless steel rod for corrosion resistance and a magnetic piston (-S) for position sensing. The extruded aluminum barrel integrates dual sensor grooves compatible with AirTAC CMSE reed and DMSE electronic solid-state switches. The rear adjuster functions purely as a travel stop to decelerate and set the end-of-stroke position, meaning it does not lock or hold the load without continuous 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 SAIJ80BX270-10S Is Used
Machine Changeover
Dial in the retract stop within the 260-270mm window during product size changes to set new end positions without replacing the cylinder.
End-Position Calibration
Fine-tune the final retract position during commissioning using the rear screw, avoiding the need to add external mechanical stops.
Variable Stops
Adjust the travel limit on packaging or conveying lines to accommodate different package lengths precisely.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80BX270-10S the Right Cylinder?
The 10mm adjustable range is ideal for dialing in exact retract positions during machine commissioning or product changeover, eliminating the need to bolt on external stops or swap out a fixed-stroke SAI cylinder. To match this ISO 15552 footprint, specify an 80mm bore, 270mm stroke, 10mm adjustment, PT tapered ports, and the -S magnet. Because the nominal stroke is 270mm, ensure proper external guiding to prevent excessive side-loading on the 25mm rod. For applications requiring true load-holding without live air, select the SAIL or BSAI series instead.
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 SAIJ80BX270-10S FAQ
It can reach a maximum thrust of 513kgf at 1.0MPa.
The rear adjuster screw lets you shorten the 270mm nominal stroke by up to 10mm, creating a 260-270mm usable travel window. It acts as a stop to set the end position and does not hold the load without live air.
