About the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX125-30
The AirTAC SAIJ32X125-30 is a double-acting, double-rod ISO 15552 profile cylinder equipped with a rear stroke adjuster. It provides a 125mm nominal stroke that can be dialed back by up to 30mm, creating a precise 95-125mm usable travel window for commissioning without external stops.
This variant features a SUS420J2 stainless steel rod (material code A) for improved corrosion resistance and uses PT tapered port threading. The extruded aluminum barrel includes sensor grooves on both sides, and while this unit lacks a magnet, the grooves are ready to accept CMSE reed or DMSE electronic sensors when needed.

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 SAIJ32AX125-30 Is Used
End-Position Tuning
Dial in the exact retract distance within the 95-125mm window during machine commissioning without swapping out the entire cylinder.
Product Changeover
Quickly adjust the stroke stop on the rear screw when switching between product sizes on a packaging line.
Is the Airtac Adjustable Cylinder SAIJ32 SAIJ32AX125-30 the Right Cylinder?
The 30mm rear adjustment screw is ideal for variable end-stops during machine setup, offering a distinct advantage over a fixed-stroke SAI cylinder by allowing you to fine-tune the retract position on the fly. Keep in mind the rear adjuster acts as a travel stop, not a lock; the SAIJ cannot hold a load without live air, so for fail-safe load holding, consider an external rod lock or the SAIL series.
Because this is an ISO 15552 profile cylinder, it is dimensionally interchangeable with other ISO 15552 cylinders. The SAIJ mounting set includes Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting the FB, CA, CB, and CR options. Since the 125mm stroke is under 300mm, side-load concerns are minimal, but always ensure the M10x1.25 rod thread is aligned to prevent binding.
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 SAIJ32AX125-30 FAQ
At the maximum 1.0MPa pressure, it can deliver up to 82kgf.
The rear adjuster screw allows you to shorten the effective stroke by up to 30mm from the 125mm nominal length, giving a usable travel window of 95-125mm. It acts as a mechanical stop to fine-tune the end position and does not lock the load without live air pressure.
