About the Airtac MIJ Adjustable Cylinder MIJ40X350-10
Trimming the forward end position by up to 10 mm on site, this round-body mini cylinder lets you fine-tune the extend stroke from 340 to 350 mm without changing the unit. The external stop screw shortens the extend end only, while retract remains full. Built with a stainless-steel barrel and a Ø16 mm piston rod, it provides mild corrosion and washdown resistance for demanding environments.
It features a 1/4" air port, an M12x1.25 male rod thread, and fixed TPU bumper pads to decelerate the stroke end. Note that this SKU lacks a magnet and cannot accept position sensors.

| 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 MIJ40X350-10 Is Used
Heavy Carton Flap Folder
Fine-tune the forward stop by 10 mm to accommodate varying carton depths, using the 32 kg vertical lift capacity to fold thick cardboard flaps.
Component Press Station
Dial in the precise end position for pressing bearings, absorbing final impact with fixed TPU bumper pads while applying up to 879.6 N at 0.7 MPa.
Is the Airtac MIJ Adjustable Cylinder MIJ40X350-10 the Right Cylinder?
The 10 mm extend adjustment window is ideal for taking up mechanical tolerances during setup or matching multiple fixtures with a single part number. Because the stop screw only sets the end position, it cannot act as a mid-stroke lock.
This cylinder does not hold its load on air loss; the piston will drift, so utilize an external rod lock or pilot-operated check valve for suspended loads. Mounting options include LB foot, FA flange, and TC trunnion (the SDB pivot-block is not available on this adjustable variant). To add CMSG, DMSG, or EMSG sensors, you must select the -S magnet variant, as this SKU cannot take a switch.
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 MIJ40X350-10 FAQ
The theoretical maximum force is 128.1 kgf at 1.0 MPa.
An external stop screw shortens the extend stroke by up to 10 mm on site, letting you set the forward end position without swapping cylinders; retract remains full. This SKU has no magnet and cannot take sensors, but choosing the -S variant enables CMSG, DMSG, and EMSG switches.
