About the Airtac MIJ Adjustable Cylinder MIJ40X40-10S
Dial in a precise forward end position on-site with the AirTAC MIJ40X40-10S, a round-body stainless steel mini cylinder featuring a 10mm extend-stroke adjustment window. An external stop screw lets you shorten the forward stroke from its 40mm nominal length down to 30mm without changing parts, while the retract stroke remains full. This enables rapid machine changeover and absorbs mechanical tolerances directly at the fixture.
The included piston magnet (-S) supports CMSG, DMSG, and EMSG sensors, and the 1/4" port handles the necessary air volume for high-force moves.
Airtac MIJ Adjustable Cylinder MIJ40X40-10S Technical Specifications
| Model | Airtac MIJ Adjustable Cylinder MIJ40X40-10S |
|---|---|
| Series | MIJ mini cylinder |

| Stroke | 40 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 MIJ40X40-10S Is Used
Precision Stop Gauging
Use the 10mm extend adjustment to fine-tune a 32kg material stop block on a heavy-duty assembly line, ensuring exact forward placement without machining new spacers.
Vertical Lift Gates
Lift lower-tier gates weighing around 32kg in a washdown-capable sorting hub, relying on the stainless construction and fixed TPU bumper pads to soften the stroke end.
Is the Airtac MIJ Adjustable Cylinder MIJ40X40-10S the Right Cylinder?
The 10mm stop screw is ideal for taking up slack in tooling setups, but remember the screw only sets the end position—it is not a mid-stroke lock. The piston will drift on air loss, so fit an external rod lock or pilot check valve if you must hold a suspended load. Mount via LB foot, FA flange, or TC trunnion (SDB pivot blocks are not available on this adjustable variant), and rely on the -S magnet for electronic position 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 MIJ40X40-10S FAQ
This 40mm bore cylinder uses a 1/4" port and a 16mm rod. The theoretical maximum force is 128.1kgf at 1.0MPa.
An external stop screw shortens the extend stroke by up to 10mm (usable range 30-40mm), but it only affects the forward end position; retract is always full. The -S suffix means a piston magnet is built-in for CMSG, DMSG, or EMSG sensors. The fixed TPU bumpers decelerate the stroke end but do not lock the position.
