About the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX120-30
The AirTAC SAIJ32X120-30 is a double-acting ISO 15552 profile cylinder featuring a rear stroke adjuster that allows you to trim the effective travel back by up to 30 mm. This creates a highly useful 90-120 mm usable stroke window, letting you dial in the exact end position during commissioning without adding bulky external stops.
Built with a SUS420J2 stainless steel piston rod, this 32 mm bore cylinder provides better corrosion resistance than standard carbon steel. The extruded aluminum barrel includes sensor grooves on both sides for flexible mounting of CMSE reed or DMSE electronic sensors if you add a magnet later. It supports the standard SAIJ mounting set (Basic, FA, LB, TC, FTC, TCM1, TCM2) while omitting the FB, CA, CB, and CR options.

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 SAIJ32AX120-30 Is Used
Machine Setup and Changeover
Fine-tune the 90-120 mm travel window during product family changeovers to accommodate different package sizes without physically swapping the cylinder.
Variable End-Stop Positioning
Dial in the exact retract position during initial commissioning to perfect the pick-and-place timing on automated assembly lines.
Conveyor Diverting Adjustment
Adjust the retract stroke on the fly to change the diverting distance for varying product widths moving down a packaging conveyor.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX120-30 the Right Cylinder?
Choose this 32 mm bore adjustable cylinder when your application requires precise end-position tuning at setup or during product changeovers. The rear adjuster acts strictly as a travel stop and cannot hold a load without live air pressure; for fail-safe load holding, consider the SAIL or BSAI series instead. When matching your ISO 15552 replacement, verify the 120 mm nominal stroke, 30 mm adjustment range, PT G1/8 port, and the specific mounting accessory set.
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 SAIJ32AX120-30 FAQ
The rear adjuster lets you shorten the 120 mm nominal stroke by up to 30 mm, providing a usable travel window of 90-120 mm. It functions as a mechanical stop for end-position tuning and does not lock or hold the load without continuous air pressure.
At the maximum operating pressure of 1.0 MPa, it can deliver up to 82 kgf of push force.
