About the Airtac MIJ Adjustable Cylinder MIJ40X250-10S
Dial in a precise forward end position on-site with the AirTAC MIJ40X250-10S, a round-body stainless steel mini cylinder featuring a 10mm adjustable extend stroke window.
Built with a riveted stainless barrel and rod, this double-acting unit shrugs off mild corrosion and washdown environments. Because this is a Ø40 bore, it uses a non-ISO-6432 round-body format. The integrated -S piston magnet supports CMSG, DMSG, and EMSG position switches, while fixed TPU bumper pads absorb impact at the stroke ends. The external stop screw shortens the extend stroke only; retract remains full.
Airtac MIJ Adjustable Cylinder MIJ40X250-10S Technical Specifications
| Model | Airtac MIJ Adjustable Cylinder MIJ40X250-10S |
|---|---|

| Bore size | Ø40 mm |
| Stroke | 250 mm |
| Acting type | Double acting, double rod, adjustable stroke |
| Port size | 1/4" |
| Rod thread | M12×1.25 |
| Fluid | Air (filtered by 40µm element) |
|---|---|
| Operating pressure | 0.15 – 1.0 MPa |
| Proof pressure | 1.5 MPa |
| Temperature | -20 to +70 °C |
| Speed range | 30 – 800 mm/s |

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 Ø40 bore is a larger, non-ISO-6432 size.
Theoretical Output Force (Ø40mm)
| Pressure | Force (both ways) |
|---|---|
| 0.5 MPa | 528 N |
| 0.7 MPa | 739 N |
| Max (@1.0 MPa) | 108 kgf |
MIJ / MICJ are double-rod: the rear rod that carries the stroke adjuster exits the rear cover, so both piston faces lose rod area. The rod-side (annular) area is used for both directions (conservative).

Where the Airtac MIJ Adjustable Cylinder MIJ40X250-10S Is Used
Heavy Diverter Gate
Positions a heavy flow diverter on a packaging line, using the 10mm extend adjustment to fine-tune the gate angle for different carton widths without swapping hardware.
Vertical Press Platen
Drives a small pressing assembly downward.
Is the Airtac MIJ Adjustable Cylinder MIJ40X250-10S the Right Cylinder?
When sizing this 40mm bore, stepping down to a MIJ32 drops the 0.5MPa push force to 402.2N, whereas no larger MIJ bore exists. The 10mm extend-stop adjustment is ideal for taking up mechanical tolerances during setup or covering multiple intermediate stop points without changing the cylinder part number. Remember that the stop screw sets the end position but acts as neither a mid-stroke lock nor a brake. If the application must hold a load on air loss, fit an external rod lock or pilot check valve, as the piston will drift. Mount via LB foot, FA flange, or TC trunnion (SDB is unavailable), and use the -S magnet for electronic sensing.
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 MIJ40X250-10S FAQ
This 40mm bore cylinder uses a 1/4" port. The theoretical maximum force is 128.1kgf at 1.0MPa.
An external stop screw shortens the extend stroke by up to 10mm on-site, giving a usable forward range of 240-250mm; the retract stroke remains full. The -S suffix means a piston magnet is built-in, allowing you to mount CMSG, DMSG, or EMSG sensors for position detection.
