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. In this configuration, it delivers 2513 N of push force and 2268 N of pull force at a 0.5 MPa operating pressure.
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.

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.
Assembly Pressing
Apply 2513 N of push force at 0.5 MPa for pressing bearings or pins, fine-tuning the final bottoming position to prevent over-travel.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX350-10S the Right Cylinder?
Choose this 80 mm bore when an application requires roughly 2513 N of thrust at 0.5 MPa, stepping up from a 63 mm bore that yields 1559 N. 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 0.5 MPa, it provides 2513 N of push force and 2268 N of pull force. At the maximum 1.0 MPa operating pressure, it delivers 513 kgf.
