About the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX155-40S
The AirTAC SAIJ80X155-40-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, providing a usable travel window of 115 to 155 mm. The barrel features sensor grooves on both sides, and the integrated magnet works seamlessly with CMSE reed and DMSE electronic solid-state switches for precise position detection.
This model features a SUS420J2 stainless steel rod (code A) and PT tapered port threads. The rear adjustment screw allows you to fine-tune the retract end position at commissioning without adding external stops. Remember that this adjuster acts purely as a travel stop and does not hold the load without live air; for pilot-operated locking, consider the SAIL or BSAI series.

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 SAIJ80AX155-40S Is Used
Machine Changeover
Dial in the 115-155 mm travel window during product size changes without swapping cylinders or adding external mechanical stops.
End-Position Tuning
Fine-tune the retract stroke by up to 40 mm during commissioning to achieve perfect alignment and prevent mechanical crashing.
Variable Stops
Adjust the end-stop on the fly for conveyor sorting arms that handle multiple package sizes within the 155 mm nominal stroke.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX155-40S the Right Cylinder?
The 40 mm adjustment range is perfect for product-size changeovers on a line, giving you a 115-155 mm window to dial in the exact end position. For a fixed end-stop without the need for commissioning tweaks, a standard SAI cylinder is sufficient. To match this ISO 15552 dimensionally interchangeable cylinder, specify the 80 mm bore, 155 mm stroke, 40 mm adjust, PT G3/8 port, and the -S magnet. The 25 mm rod and M20x1.5 thread handle high side loads well, but for any stroke of 300 mm or more, an external guide is still required.
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 SAIJ80AX155-40S FAQ
The rear adjuster screw lets you shorten the effective stroke by up to 40 mm, creating a usable travel window of 115 to 155 mm. It acts as a physical stop to fine-tune the end position but does not lock the load without continuous air pressure.
At the maximum operating pressure of 1.0 MPa, the push force reaches 513 kgf.
