About the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX350-10S
The AirTAC SAIJ80X350-10-S is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a usable travel window of 340 to 350 mm, enabling precise end-position tuning at commissioning without adding external stops.
This SKU includes a SUS420J2 stainless steel rod for superior corrosion resistance and a PT tapered port thread. The extruded aluminum barrel integrates dual sensor grooves, and the included magnet (-S) supports CMSE reed and DMSE electronic solid-state switches. The rear adjuster acts purely as a travel stop to set deceleration, not as a load lock.

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 SAIJ80AX350-10S Is Used
End-Stop Calibration
Dial in the exact 340-350 mm retract position during machine commissioning to perfect product placement without machining external spacers.
Product Changeover
Quickly adapt the stroke window for different package sizes on a packaging line, using the rear screw to shift the end position by up to 10 mm.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX350-10S the Right Cylinder?
The 10 mm adjustment range is ideal for product changeovers that need a variable end-stop rather than a fixed stroke SAI cylinder. For holding loads without live air pressure, select a SAIL or BSAI series instead, as this adjuster is not a brake.
When replacing an ISO 15552 cylinder, match the 80 mm bore, 350 mm stroke, 10 mm adjustment, PT G3/8 port, and -S magnet. Because the 350 mm stroke is long, the 25 mm rod diameter and M20x1.5 thread still require an external guide to prevent excessive side-loading on the piston.
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 SAIJ80AX350-10S FAQ
The rear adjuster is a mechanical stopper that lets you shorten the effective stroke by up to 10 mm, creating a 340-350 mm travel window. It sets the end position but does not lock the load without live air.
At the maximum 1.0 MPa operating pressure, it delivers 513 kgf.
