About the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX145-40
The AirTAC SAIJ32X145-40 is a double-acting ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a 145mm nominal stroke that can be fine-tuned backward by up to 40mm, creating a usable travel window of 105-145mm.
This configuration includes a SUS420J2 stainless steel rod (option A) for improved corrosion resistance and uses PT tapered port threads with a G1/8 connection. The extruded aluminum barrel integrates sensor grooves on both sides, though position detection requires adding a magnet (-S) to work with AirTAC CMSE reed or DMSE electronic sensors.

Theoretical Output Force (Ø32mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 346 N | 346 N |
| 0.7 MPa | 484 N | — |
| Max (@1.0 MPa) | 70 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 Adjustable Cylinder SAIJ32 SAIJ32AX145-40 Is Used
Machine Changeover
Dial in the exact end-stop from 105 to 145mm when switching between product sizes on a packaging line, avoiding physical cylinder replacement.
Fixture Alignment
Fine-tune the retract position during initial commissioning to perfectly seat parts without machining custom external stopper blocks.
Variable End Stops
Accommodate multiple material thicknesses on a single workstation by adjusting the rear screw to alter the effective stroke depth on demand.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX145-40 the Right Cylinder?
Choose this 32mm bore when an application requires precise end-position tuning during commissioning or product changeover without swapping cylinders. The rear adjustment screw acts purely as a travel stop to decelerate the piston; it does not hold the load without live air pressure. For true load-holding, consider the SAIL or BSAI series.
To match this ISO 15552 replacement, verify the 145mm stroke, 40mm adjustment range, G1/8 PT port, and the SUS420J2 rod material. Because the stroke is under 300mm, side-load stress on the 12mm rod is minimal, but long unsupported loads still require an external guide. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting the FB, CA, CB, and CR options.
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 Adjustable Cylinder SAIJ32 SAIJ32AX145-40 FAQ
The rear adjuster screw acts as a mechanical stop that can shorten the effective travel by up to 40mm. This gives the 145mm stroke a usable window of 105-145mm, allowing you to fine-tune the retract end position without adding external stops.
