About the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX20-20
The AirTAC SAIJ80X20-20 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster. It provides a nominal 20 mm stroke that can be dialed back by up to 20 mm, yielding a highly precise 0-20 mm usable travel window for exact end-position tuning at commissioning.
This variant uses a SUS420J2 stainless steel rod for improved corrosion resistance and features PT tapered port threads. The extruded aluminum barrel includes sensor grooves on both sides for flexible switch mounting. It supports a speed range of 30-800 mm/s and relies on adjustable air cushions at both ends to decelerate the load smoothly.

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 SAIJ80AX20-20 Is Used
Precision Clamping Stops
Dial in the exact clamping end-position on varying material thicknesses without installing external physical stoppers on the machine frame.
Machine Changeover
Rapidly adjust the travel end-stop during product size changeovers, using the 0-20 mm rear screw to fine-tune the motion profile on the fly.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX20-20 the Right Cylinder?
Choose this 80 mm bore adjustable-stroke cylinder when an application requires exact end-stop calibration without swapping components or adding external stops. The rear adjuster acts purely as a travel stop and does not hold the load without live air; for true fail-safe load holding, consider the SAIL or BSAI series instead.
Because the 20 mm stroke is very short, side-load risks are minimal, but the 25 mm rod diameter and M20x1.5 thread provide excellent rigidity for absorbing offset forces. This SAIJ model uses the reduced mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2) and omits FB, CA, CB, and CR brackets. It is dimensionally interchangeable per ISO 15552 without relying on tie-rod construction.

- ✓ 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 SAIJ80AX20-20 FAQ
It can reach a maximum thrust of 513 kgf at 1.0 MPa.
The rear adjusting screw acts as a mechanical stop that trims the effective travel. For this SAIJ80X20-20 model, you can shorten the 20 mm nominal stroke by up to 20 mm, creating a 0-20 mm adjustable travel window. It requires live air to hold position and is not a locking device.
