About the Airtac MIJ Adjustable Cylinder MIJ32X80-20S
Trimming the forward end by up to 20 mm on site, the MIJ32X80-20S lets you dial in a precise 60-80 mm extend position without swapping hardware. This round-body stainless mini cylinder handles heavier pushes with 402.2 N of force at 0.5 MPa, yielding a safe working load of roughly 241 N or a 20.5 kg vertical lift with a 2:1 margin.
The stainless-steel barrel and Ø12 mm rod shrug off mild corrosion and washdown environments. Because this is a -S SKU, a built-in piston magnet supports CMSG, DMSG, or EMSG position switches. Air connects via a 1/8" port, and fixed TPU bumper pads decelerate the stroke end. Note that Ø32 is a non-ISO-6432 round-body size.

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 MIJ32X80-20S Is Used
Staged Diverting
Dial the 20 mm extend stop to push mixed cartons accurately onto secondary lines without changing the cylinder body.
Tolerance Take-up
Absorb carton size variances on the fly, using the adjustable forward end to press and seal flaps cleanly at 402.2 N.
Changeover Setup
Shift the extend position for new fixture runs quickly, leveraging the 241 N safe working load to push tooling into place.
Is the Airtac MIJ Adjustable Cylinder MIJ32X80-20S the Right Cylinder?
If 402.2 N at 0.5 MPa is excessive, stepping down to the MIJ25 bore drops the push force to 245.3 N; conversely, the MIJ40 pushes 628.3 N if your payload grows. The 20 mm external stop screw is ideal for absorbing mechanical tolerances or staging feeds, letting one part number cover several end stops.
The stop screw sets the forward position but is not a mid-stroke lock; the piston drifts on air loss, so fit an external rod lock or pilot check valve for held loads. Mount using LB foot, FA flange, or TC trunnion (SDB pivot-block is unavailable here), and operate between 30-800 mm/s.
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 MIJ32X80-20S 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 is 82 kgf at 1.0 MPa. The air port is 1/8".
An external stop screw shortens the extend stroke by up to 20 mm (retract remains full). The -S suffix means a magnet is built in for CMSG/DMSG/EMSG sensors. The screw is not a mid-stroke lock.
