About the Airtac MIJ Adjustable Cylinder MIJ40X350-75
Dial in your forward end position on-site with the AirTAC MIJ40X350-75, a round-body stainless steel mini cylinder built for double-acting operation. An external stop screw lets you shorten the extend stroke by up to 75 mm, giving a usable forward range of 275 to 350 mm without changing the part number. Retract travel remains at the full 350 mm. The fixed TPU bumper pads decelerate the piston near the stroke ends.
This Ø40 mm bore delivers substantial force, pushing with 628.3 N and pulling with 527.8 N at 0.5 MPa. The stainless barrel and rod resist mild corrosion and washdown environments. Note this larger bore uses a 1/4" port and a M12x1.25 male rod thread, and as a non-magnet SKU, it cannot host 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 MIJ40X350-75 Is Used
Press Fit Tuning
Use the 75 mm extend adjustment to fine-tune the pressing depth of heavy pins.
Variable Length Diverter
Position packages of varying sizes on a line by adjusting the extend stop on the fly.
Pallet Changeover Stop
Set precise end stops for different pallet widths without changing cylinders. The stainless construction withstands damp handling areas, and the 1/4" port delivers the volume needed for fast cycling.
Is the Airtac MIJ Adjustable Cylinder MIJ40X350-75 the Right Cylinder?
The 75 mm adjustment window is highly useful for taking up mechanical tolerances during setup or staging feeds across changeover jobs. You can fine-tune the exact forward stop without swapping hardware.
Mounting options include LB foot, FA flange, and TC trunnion, but the SDB pivot block is not available on this adjustable variant. Because it lacks the -S magnet, this specific SKU cannot accept position sensors. Remember that the stop screw only sets the end position; it is not a mid-stroke lock. The piston will drift on air loss, so fit 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 MIJ40X350-75 FAQ
At 0.5 MPa, this double-acting cylinder pushes with 628.3 N and pulls with 527.8 N. At 0.7 MPa, push is 879.6 N and pull is 738.9 N. The theoretical maximum force is 128.1 kgf at 1.0 MPa. It uses a 1/4" air port and a M12x1.25 male rod thread.
An external stop screw shortens the extend stroke by up to 75 mm, allowing you to set the forward end position between 275 and 350 mm. Retract is always the full 350 mm. This SKU lacks a magnet, so it cannot take CMSG, DMSG or EMSG sensors; you would need the -S variant for sensing.
