About the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX160-20S
The AirTAC SAIJ80X160-20-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, providing a usable travel window of 140 to 160 mm for precise end-position tuning. A pre-installed magnet enables position detection using CMSE reed or DMSE electronic sensors.
This model features a G3/8 port and uses PT tapered threading for secure pneumatic connections. The extruded aluminum barrel incorporates dual sensor grooves, and the adjustable stopper allows you to dial in the retract distance during commissioning without adding external stops. The adjuster acts purely as a travel limit and does not lock the load without live air pressure.

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 SAIJ80AX160-20S Is Used
Product Changeover
Quickly dial back the stroke by up to 20 mm when switching box sizes on a packaging line, avoiding mechanical rebuilds.
End-Stop Calibration
Fine-tune the final retract position during machine commissioning to achieve exact clamping or pressing depths.
Variable Diverter
Adjust the actuator reach on the fly to deflect different product profiles without moving the cylinder mount.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX160-20S the Right Cylinder?
Choose this 80 mm bore when an application requires higher thrust than a 63 mm cylinder, which provides 2182 N at 0.7 MPa. The 20 mm adjustment range is ideal for product changeovers on a packaging line, allowing operators to fine-tune the 160 mm stroke on the fly rather than swapping to a fixed-stroke SAI cylinder. For holding loads safely without continuous air pressure, integrate an external pilot-operated check valve or select the SAIL or BSAI locking cylinder variants.
When replacing an ISO 15552 cylinder, match the 80 mm bore, 160 mm nominal stroke, 20 mm adjustment, G3/8 PT port, and the -S magnet requirement. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2 options, omitting FB, CA, CB, and CR. Although the 25 mm rod handles side loads well, always support long strokes with an external guide.
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 SAIJ80AX160-20S FAQ
The rear adjuster screw acts as a mechanical stop, allowing you to shorten the 160 mm nominal stroke by up to 20 mm. This creates a 140 to 160 mm usable travel window for fine-tuning the end position without replacing the cylinder.
