About the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX120-75
The AirTAC SAIJ32X120-75 is a double-acting, double-rod ISO 15552 profile cylinder featuring a rear-mounted stroke adjuster. It provides a nominal 120 mm stroke that can be dialed back by up to 75 mm, yielding a highly flexible 45-120 mm usable travel window for exact end-position tuning at commissioning.
This variant is configured with an SUS420J2 stainless steel rod (material code A) for improved corrosion resistance compared to standard carbon steel. It uses PT tapered port threads (G1/8) and operates without a magnet. The rear adjuster acts strictly as a mechanical stop to fine-tune the retract position without swapping the cylinder or adding external stops; it does not hold the 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 SAIJ32AX120-75 Is Used
End-Position Tuning
Dial in the exact retract distance within the 45-120 mm window during machine commissioning without swapping out physical spacers.
Product Changeover
Quickly adapt the retract stroke stop on packaging lines when switching to different product sizes or formats.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX120-75 the Right Cylinder?
The generous 75 mm adjustment window on a 120 mm stroke allows wide positioning flexibility. For load-holding without live pressure, this cylinder is insufficient as the adjuster is only a travel stop, not a lock; consider the SAIL or BSAI series instead.
To match this ISO 15552 dimensionally interchangeable cylinder, specify: 32 mm bore, 120 mm stroke, 75 mm adjustment, PT G1/8 port, Basic/FA/LB/TC/FTC/TCM1/TCM2 mounting, and no magnet. The 12 mm rod and M10x1.25 thread handle moderate side loads, though long unsupported strokes still 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 SAIJ32AX120-75 FAQ
The rear adjuster acts as a mechanical stop that lets you shorten the effective stroke by up to 75 mm from the 120 mm nominal length, giving a usable travel window of 45 to 120 mm. It is a travel stop, not a lock, so it will not hold the load without live air pressure.
