About the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX600-20S
The AirTAC SAIJ80X600-20-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, delivering 4523N of push force at 0.9 MPa. 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.

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.
Heavy Material Handling
Leverage the 4523N push force at 0.9 MPa to move heavy pallets or fixtures, using the rear stop to fine-tune the resting position.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX600-20S the Right Cylinder?
Choose this 80mm bore when an application requires substantially more thrust than a 63mm cylinder (which provides 2805N push at 0.9 MPa), but without the physical bulk of a 100mm unit. 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
At an operating pressure of 0.9 MPa, this 80mm bore cylinder generates a push force of 4523N and a pull force of 3681N. At 0.5 MPa, it provides 2513N of push force.
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.
