About the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX225-10
The AirTAC SAIJ80X225-10 is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster. It provides a nominal 225 mm stroke with a 10 mm external adjustment range, yielding a usable travel window of 215 to 225 mm for precise end-position tuning at commissioning.
This variant features a SUS420J2 stainless steel piston rod for improved corrosion resistance and uses PT tapered port threads with a G3/8 connection. The extruded aluminum barrel includes sensor grooves on both sides for flexible mounting of CMSE reed or DMSE solid-state switches. The rear adjuster functions strictly as a mechanical stop to fine-tune travel and is not a locking device.

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 SAIJ80AX225-10 Is Used
Machine Setup Calibration
Dial in the exact retract position within a 215-225 mm window during initial commissioning without swapping out the entire cylinder.
Product Changeover
Quickly adjust the end-stop by up to 10 mm on a packaging line when processing slightly different carton sizes or formats.
Variable End-Positioning
Fine-tune the stroke endpoint on an assembly press to accommodate component tolerances, using the rear stopper instead of external blocks.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX225-10 the Right Cylinder?
The 10 mm adjustable stroke window is ideal for product changeovers or setup refinement, allowing you to dial in the exact retract position without adding external stops or swapping a fixed-stroke SAI cylinder. If the machine requires the load to be held in place without live air pressure, this standard SAIJ adjuster will not suffice; you must use a SAIL air-released lock, a BSAI clamp-lock, or an external rod lock.
Because the 225 mm stroke exceeds 200 mm, the 25 mm diameter rod and M20x1.5 rod thread provide robust support, but an external guide is still recommended to prevent excessive side loading on long unsupported travels. This model is dimensionally interchangeable per ISO 15552 and supports a reduced mounting set including Basic, FA, LB, TC, FTC, TCM1, and TCM2.
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 SAIJ80AX225-10 FAQ
The rear adjuster acts as a mechanical stop that allows you to shorten the effective stroke by up to 10 mm. This creates a usable travel window of 215 to 225 mm, letting you fine-tune the end position during commissioning. It is a travel stop, not a lock, and does not hold the load without live air pressure.
At the maximum operating pressure of 1.0 MPa, it can deliver up to 513 kgf of push force.
