About the Airtac MIJ Adjustable Cylinder MIJ40X60-30
Dial in your forward end position on-site with the AirTAC MIJ40X60-30, a round-body stainless mini cylinder featuring a 30 mm extend adjustment window. An external stop screw lets you shorten the forward stroke from its 60 mm nominal length down to 30 mm, absorbing setup tolerances without changing the part number. The retract stroke remains full length. Built with a riveted stainless-steel barrel and Ø16 rod, it handles mild corrosion and washdown environments.
It uses a 1/4" port, runs at 30-800 mm/s, and relies on fixed TPU bumper pads to decelerate the stroke end.

| Stroke | 60 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 MIJ40X60-30 Is Used
Variable Stroke Press
Fine-tune the forward pressing position on-site for different package heights without swapping cylinders, relying on fixed TPU bumpers to absorb the 32 kg vertical lift impact.
Washdown Product Ejector
Leverage the stainless steel round-body construction and 1/4" port air supply to eject dense parts from a washdown line, adjusting the ejector reach to match fixture tolerances.
Is the Airtac MIJ Adjustable Cylinder MIJ40X60-30 the Right Cylinder?
The 30 mm external stop screw is ideal for changeover jobs where you need one part number to cover several intermediate forward stops, though you must specify the exact travel during mechanical setup.
Remember that the stop screw only trims the extend end; it 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 is unavailable). Because this SKU lacks the -S magnet, it cannot accept CMSG, DMSG, or EMSG sensors.
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 MIJ40X60-30 FAQ
The theoretical maximum force is 128.1 kgf at 1.0 MPa.
An external screw shortens the extend stroke by up to 30 mm on-site, letting you dial in the forward end position without replacing the cylinder; retract remains full. The screw is not a mid-stroke lock, and the piston will drift on air loss. This SKU has no -S magnet, so it cannot take sensors.
