About the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX185-10
The AirTAC SAIJ80X185-10 is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, allowing you to fine-tune the end position at commissioning. Based on an 80mm bore and a 185mm nominal stroke, the external stopper provides a 10mm adjustment range, creating a precise 175-185mm usable travel window without adding external stops.
This configuration features a SUS420J2 stainless steel rod (option A) for enhanced corrosion resistance and uses PT tapered port threads. The extruded aluminum barrel includes sensor grooves on both sides for flexible mounting of CMSE reed or DMSE electronic solid-state switches. Remember that the rear adjuster acts strictly as a travel stop combined with variable air cushions at both ends to decelerate the load; it does not hold the position without live air pressure.

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 SAIJ80AX185-10 Is Used
End-Position Tuning
Dial in the exact retract distance within the 175-185mm window during machine commissioning to achieve precise positioning without machining external stoppers.
Product Changeover
Quickly adapt the cylinder's effective stroke on the line when introducing a new product size, saving downtime by adjusting the rear screw rather than replacing hardware.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX185-10 the Right Cylinder?
Choose this 80mm bore adjustable cylinder when your application requires a 175-185mm stroke window and high force, delivering 2513N of pull force at 0.5 MPa. If your setup needs less force, stepping down to a 63mm bore yields 1402N of pull force, while moving up to a 100mm bore provides 3681N of pull force at the same pressure. The adjustable stroke is ideal for product changeovers or fine-tuning end positions on the machine without physically swapping the cylinder. For load-holding requirements without live air pressure, this plain SAIJ model is insufficient since the adjuster is a stop, not a lock; consider the SAIL (air-released lock) or BSAI (clamp-lock) variants instead. This model is dimensionally interchangeable per ISO 15552 and uses a reduced mounting set including Basic, FA, LB, TC, FTC, TCM1, and TCM2.

- ✓ 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 SAIJ80AX185-10 FAQ
The rear adjuster acts as an external stopper that lets you shorten the effective stroke by up to 10mm, providing a usable travel window of 175-185mm. It allows fine-tuning of the end position during setup without swapping the cylinder, though it functions as a stop and not a lock.
At the maximum operating pressure of 1.0 MPa, it delivers up to 513 kgf (around 5030N) of push force.
