About the Airtac MIJ Adjustable Cylinder MIJ40X75-30S
Dial in a precise forward end position on-site with the AirTAC MIJ40X75-30S, a round-body stainless steel mini cylinder featuring a 30 mm adjustable extend window. An external stop screw lets you shorten the forward stroke from its 75 mm nominal length down to 45 mm without changing parts, while the retract stroke remains full. Built with a riveted stainless barrel and rod, it handles mild washdown and corrosion exposure.
Because this is a -S SKU, it includes a piston magnet for CMSG, DMSG, or EMSG position sensing.
Airtac MIJ Adjustable Cylinder MIJ40X75-30S Technical Specifications
| Model | Airtac MIJ Adjustable Cylinder MIJ40X75-30S |
|---|---|
| Series | MIJ mini cylinder |
| Bore size | Ø40 mm |
| Stroke | 75 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 |
| Cushion | Fixed TPU bumper pads |

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 MIJ40X75-30S Is Used
Staged Press Operations
Adjust the forward end position on the fly for multi-tier pressing tasks, leveraging the 32 kg vertical lift capacity to seat components with precision before the fixed TPU bumper absorbs the stop impact.
Pallet Stop Calibration
Fine-tune the stopping depth for varying pallet sizes in a single changeover setup, utilizing the stainless construction to endure damp or washdown-heavy logistics environments.
Is the Airtac MIJ Adjustable Cylinder MIJ40X75-30S the Right Cylinder?
The 30 mm external stop screw is invaluable for taking up mechanical tolerances during setup or covering multiple intermediate stop points with a single part number.
Mount using LB foot, FA flange, or TC trunnion brackets—note that the SDB pivot block is not offered on this adjustable variant. 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 specify an external rod lock or pilot check valve if you need to hold a suspended load.
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 MIJ40X75-30S FAQ
The theoretical maximum force is 128.1 kgf at 1.0 MPa.
An external stop screw shortens the extend stroke by up to 30 mm (usable range 45-75 mm), but retract remains full. The -S suffix means it has a built-in magnet for CMSG/DMSG/EMSG sensors. It uses fixed TPU bumper pads, not an adjustable air cushion.
