About the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX145-30S
The AirTAC SAIJ80X145-30-S is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, providing a usable travel window of 115-145 mm from its 145 mm nominal stroke. The extruded aluminum barrel features sensor grooves on both sides, and the integrated magnet supports position feedback via CMSE reed or DMSE electronic switches.
This model utilizes a SUS420J2 stainless steel piston rod (material code A) for enhanced corrosion resistance compared to standard carbon steel. The adjuster functions strictly as a mechanical stop to set the retract end position; it does not lock or hold the load without continuous live air pressure. For applications requiring true load-holding, consider the SAIL or BSAI series instead.

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 SAIJ80AX145-30S Is Used
Product Changeovers
Dial in the exact 115-145 mm stroke end-position during line changeovers without swapping the cylinder or adding external shims.
Machine Setup Tuning
Fine-tune the retract end-stop at commissioning to perfectly time the mechanical motion against a fixed datum.
Variable End Stops
Accommodate slight variations in product sizes on the fly by adjusting the rear stopper within its 30 mm range.
Is the Airtac SAIJ80 Adjustable Cylinder SAIJ80AX145-30S the Right Cylinder?
The 25 mm piston rod and M20x1.5 thread provide robust resistance to side loading, though any stroke exceeding 300 mm still necessitates an external guide. The PT tapered port threads ensure a tight, reliable pneumatic connection.
If your force requirements are lower, the SAIJ63 bore offers 1559 N at the same pressure. The defining advantage here over a fixed SAI cylinder is the 30 mm adjustment range, which is ideal for machine setups requiring frequent product-size changeovers. Remember that the rear stopper only decelerates and sets the travel end—it is not a brake, so you must maintain air pressure to hold a load.
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 SAIJ80AX145-30S FAQ
The rear adjuster acts as a mechanical stop that lets you trim the effective stroke back by up to 30 mm, giving a usable travel window of 115-145 mm. It sets the end position but does not lock the load without live air pressure.
