About the Airtac MIJ Adjustable Cylinder MIJ40X500-75S
Dial in a precise forward end position on-site with the AirTAC MIJ40X500-75S, a round-body stainless steel mini cylinder featuring a 75 mm extend-stroke adjustment window. This double-acting actuator uses an external stop screw to trim the forward travel down from its 500 mm nominal maximum, allowing one part number to cover several stroke lengths without swapping hardware. The retract stroke remains full length.
Built with a stainless-steel barrel and Ø16 mm piston rod, it withstands mild corrosion and washdown environments. The 1/4" port feeds the chamber, and the included -S magnet enables CMSG, DMSG, or EMSG position sensing.

| 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 MIJ40X500-75S Is Used
Staged Package Diverting
Trimming the extend stroke by up to 75 mm lets a single diverter arm push various carton sizes onto different downstream lanes without changing actuators.
Variable Length Sealing
Set the exact end position for a sealing head across different bag lengths, relying on the stainless construction for washdown resistance.
Is the Airtac MIJ Adjustable Cylinder MIJ40X500-75S the Right Cylinder?
The 75 mm external stop screw is ideal for taking up mechanical tolerances during setup or matching multiple staged feed distances. Because the bore exceeds the ISO 6432 standard interface, it is strictly a round-body mini cylinder rather than an ISO interchange part.
Mounting choices include LB foot, FA flange, and TC trunnion styles, but the SDB pivot block is not available on this adjustable variant. Remember that the stop screw sets the end position but does not function as a mid-stroke lock; the piston will drift on air loss, so add an external rod lock or pilot check valve for held loads.
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 MIJ40X500-75S FAQ
This 40 mm bore cylinder uses a 1/4" port. The theoretical maximum force is 128.1 kgf at 1.0 MPa.
An external stop screw shortens the extend stroke by up to 75 mm on-site, yielding a usable forward travel of 425 to 500 mm, while the retract stroke remains full. The -S suffix denotes a built-in piston magnet for CMSG, DMSG, or EMSG sensors. Fixed TPU bumper pads decelerate the stroke ends.
