About the Airtac MIJ Adjustable Cylinder MIJ40X350-75S
Dial in your forward end position on-site with the AirTAC MIJ40X350-75S, a round-body stainless mini cylinder featuring a 75mm adjustable extend window. An external stop screw lets you trim the forward stroke down from the 350mm nominal maximum, covering multiple stop distances without swapping hardware. Retract remains full length.
The 1/4" port and M12x1.25 male rod thread handle high flow, while fixed TPU bumper pads absorb the end-of-stroke impact. The -S suffix equips the piston with a magnet for CMSG, DMSG, or EMSG sensors.

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 MIJ40X350-75S Is Used
Staged Diverting
Set precise extend stops up to 75mm short of full travel to push varying carton sizes onto secondary packaging lines without changing actuators.
Tolerance Take-up
Compensate for machine alignment drift by fine-tuning the extend endpoint on-site, ensuring a 350mm maximum stroke hits the exact target every time.
Is the Airtac MIJ Adjustable Cylinder MIJ40X350-75S the Right Cylinder?
For lighter push requirements, stepping down to the Ø32 bore yields 402.2 N at 0.5 MPa, whereas this Ø40 model provides 628.3 N. If your application exceeds that, no larger MIJ bore exists, and a different profile class is required. The 75mm adjustment window is ideal for taking up mechanical tolerances during setup or staging feeds across changeover jobs.
Remember that the external screw only sets the extend end position; it is not a mid-stroke lock. The piston will drift if air pressure drops, so fit an external rod lock or pilot check valve for holding suspended loads. Mount using LB foot, FA flange, or TC trunnion brackets (SDB pivot blocks are not offered on this adjustable variant).
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 MIJ40X350-75S FAQ
The theoretical maximum force is 128.1 kgf at 1.0 MPa. The air port is 1/4".
An external stop screw shortens the extend stroke by up to 75mm, giving a usable forward range of 275-350mm; retract is unaffected. The -S suffix means a piston magnet is installed for CMSG, DMSG, or EMSG sensors. Fixed TPU bumpers decelerate the stroke end.
