About the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX600-20S
Its built-in 20mm adjustment screw allows you to fine-tune the effective travel within a 580-600mm window. This eliminates the need to swap out the entire cylinder or bolt on external stops when dialing in a final end position during machine commissioning.
This unit features a SUS420J2 stainless steel rod for enhanced corrosion resistance and includes a magnet (-S) for direct compatibility with AirTAC CMSE reed and DMSE electronic sensors. The extruded aluminum barrel provides dual sensor grooves, and the G3/8 port ensures adequate flow for its 30-800mm/s speed range.

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 SAIJ80AX600-20S Is Used
Variable End-Stop Tuning
Dial in the exact retract position within the 580-600mm window during machine setup without physically changing the cylinder length.
Product Changeover
Quickly adjust the stroke by up to 20mm on a packaging line to accommodate different carton sizes or downstream tooling gaps.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX600-20S the Right Cylinder?
The adjustable stroke is ideal for product-size changeovers on a line, letting operators reset the retract end-stop on the fly. For an exact ISO 15552 replacement match, verify the 80mm bore, 600mm stroke, 20mm adjustment, PT port thread, and the -S magnet requirement. Because the stroke is 600mm, the 25mm rod and M20x1.5 thread still require an external guide to prevent excessive side-loading on the piston.
Keep in mind the rear adjuster acts strictly as a travel stop and does not hold the load without live air pressure. For true load-holding in the event of air loss, consider an AirTAC SAIL or BSAI cylinder 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 SAIJ80AX600-20S FAQ
The rear adjuster screw allows you to shorten the 600mm nominal stroke by up to 20mm, providing a usable travel window of 580-600mm. It functions as a mechanical stop to set the end position and is not a lock.
