About the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX165-30S
The AirTAC SAIJ80X165-30-S is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to fine-tune the effective travel anywhere within a 135 to 165 mm window. This configuration includes a SUS420J2 stainless steel rod and a built-in magnet for position sensing.
The adjustable rear stopper lets you dial in exact end positions during commissioning without adding external stops or swapping cylinders. It uses PT tapered ports and dual-side sensor grooves compatible with CMSE reed and DMSE electronic switches. The adjuster acts purely as a travel stop, so it will not hold the load 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 SAIJ80AX165-30S Is Used
Machine Setup Tuning
Dial in the exact 135 to 165 mm end-position during commissioning without external stops.
Product Changeover
Quickly adapt the cylinder's travel window for varying product sizes on the same line.
Variable End Stops
Use the rear adjuster to fine-tune deceleration and final positioning for high-force tasks.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX165-30S the Right Cylinder?
The 30 mm adjustment range is ideal for product changeovers where the precise end-of-stroke varies slightly between batches. For load-holding without continuous air pressure, use a SAIL or BSAI cylinder instead, as this adjuster is not a lock. To match this ISO 15552 replacement, specify the 80 mm bore, 165 mm stroke, 30 mm adjustment, PT ports, SUS420J2 rod, and the -S magnet.
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.
