About the Airtac MIJ Adjustable Cylinder MIJ32X125-30
Dial in a precise forward end position on-site with the AirTAC MIJ32X125-30, a round-body stainless steel mini cylinder built for double-acting operation. An external stop screw lets you shorten the extend stroke by up to 30 mm, providing a usable forward range of 95 to 125 mm without swapping parts. Retract remains at the full 125 mm. The fixed TPU bumper pads decelerate the piston near the stroke end.
This Ø32 bore delivers substantial thrust, pushing with 402.2 N and pulling with 345.6 N at 0.5 MPa. For a reliable setup, a safe working load is roughly 241 N, capable of a vertical lift around 20.5 kg with a 2:1 margin. The stainless barrel and rod resist mild corrosion and washdown environments. It features a 1/8" port, a Ø12 mm rod, and an M10x1.25 male thread. Note that Ø32 is a non-ISO-6432 size. This SKU lacks a magnet, so it cannot accept CMSG, DMSG, or EMSG sensors.

Specifications follow the official AirTAC MI/MIC (ISO 6432) datasheet. Barrel & rod: stainless steel (round-body, riveted construction). Thread options: PT (blank) / G. Note: the Ø32 bore is a larger, non-ISO-6432 size.
Theoretical Output Force (Ø32mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 402 N | 346 N |
| 0.7 MPa | 563 N | 484 N |
| Max (@1.0 MPa) | 82 kgf | |
Actual usable force is lower than theoretical due to friction and back-pressure. Size with a safety margin.

Where the Airtac MIJ Adjustable Cylinder MIJ32X125-30 Is Used
Staged Part Ejection
Trim the extend stroke up to 30 mm to push 20 kg bins off a belt without readjusting hard stops.
Tolerance Take-Up Jig
Use the 402.2 N thrust to press pins, dialing the forward end in 95-125 mm to absorb material variances.
Washdown Carton Stop
Leverage the stainless build to halt heavy cartons in damp zones, fine-tuning the contact position on-site.
Is the Airtac MIJ Adjustable Cylinder MIJ32X125-30 the Right Cylinder?
When sizing this unit, consider the next bore down (Ø25, 245.3 N push @0.5 MPa) for lighter duties, or step up to Ø40 (628.3 N push @0.5 MPa) if your load exceeds the 402.2 N capability of this 32 mm bore. The 30 mm adjustment window is ideal for taking up mechanical tolerances or staging feeds during changeovers. You can fine-tune the extend end freely, but the stop screw is not a mid-stroke lock; the piston will drift on air loss, so add an external rod lock or pilot check valve for held loads. Mount via LB foot, FA flange, or TC trunnion (SDB pivot-block is unavailable). Speeds run 30-800 mm/s at 0.15-1.0 MPa.
Quick checklist
- ✓ Required force at your working pressure
- ✓ Stroke and mounting space
- ✓ Port/thread type (PT / G)
- ✓ Magnet (-S) for sensors?
- ✓ Back cover (CA/U/R/CM) & mount (LB/FA/SDB/TC)
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 Do not dismantle the riveted front/back covers.
- check Use correct back cover (CA/U/R/CM) & mount (LB/FA/SDB/TC).
- check Installation by qualified personnel per AirTAC docs.
Airtac MIJ Adjustable Cylinder MIJ32X125-30 FAQ
At 0.5 MPa it pushes 402.2 N and pulls 345.6 N. At 0.7 MPa it pushes 563 N and pulls 483.8 N. The theoretical max force is 82 kgf at 1.0 MPa. It uses a 1/8" port, a Ø12 mm rod, and an M10x1.25 male rod thread.
An external screw shortens the extend stroke by up to 30 mm (usable range 95-125 mm); retract stays full. This screw sets the end position but is not a mid-stroke lock, so the piston drifts on air loss. This SKU has no magnet (-S required for CMSG/DMSG/EMSG sensors).
