About the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX120-20
The AirTAC SAIJ32X120-20 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster. It provides a 120mm nominal stroke that can be dialed back by up to 20mm, giving you a 100-120mm usable travel window for precise end-position tuning at commissioning. In this A-rod configuration, the piston uses a SUS420J2 stainless steel rod, and the body features PT tapered port threads.
The extruded aluminum barrel includes sensor grooves on both sides for direct mounting of CMSE reed or DMSE electronic switches. The rear adjuster acts purely as a travel stop to fine-tune deceleration, meaning it will not hold a load without live air pressure.

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 SAIJ32AX120-20 Is Used
Machine Changeover
Dial in the 100-120mm travel window during product size transitions to set exact end-stops without physically swapping the cylinder.
End-Stop Tuning
Fine-tune the final retract position during machine commissioning using the rear stopper screw to perfect the deceleration ramp.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX120-20 the Right Cylinder?
Choose this adjustable SAIJ variant when your machine setup requires variable end-stops or frequent product-size changeovers without swapping out the entire cylinder or adding external stops. If your application requires higher thrust, stepping up to a 40mm bore increases the 0.5 MPa push force to 628N. For load-holding without continuous air pressure, this cylinder is insufficient; you would need to specify a SAIL pneumatic lock or a BSAI clamp-lock cylinder instead.
To match this ISO 15552 cylinder for a replacement, verify the 32mm bore, 120mm stroke, 20mm adjustment range, PT G1/8 port, and the reduced SAIJ mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2). Because the 120mm stroke is relatively short, side-loading on the 12mm rod is minimal, though long unsupported strokes over 300mm would require an external guide.
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 SAIJ32AX120-20 FAQ
The maximum thrust is 82kgf at 1.0 MPa.
The rear adjuster screw acts as a mechanical stop that lets you trim the effective travel back by up to 20mm, creating a 100-120mm usable stroke window. It sets the travel end and deceleration point, but it does not lock or hold the load without live air pressure.
