About the Airtac MIJ Adjustable Cylinder MIJ40X450-75
Dial in a precise forward end position on-site with the AirTAC MIJ40X450-75, a double-acting round-body mini cylinder featuring a 75mm adjustable extend window. An external stop screw lets you trim the forward stroke from 450mm down to 375mm, absorbing setup tolerances without changing the part number.
This Ø40 bore unit uses a 1/4" port and M12x1.25 male rod thread. Because it is a non-ISO-6432 size, it functions purely as a robust round-body actuator. It relies on fixed TPU bumper pads to decelerate the stroke end. Note this SKU lacks a magnet, so it cannot host CMSG, DMSG or EMSG sensors.

| Stroke | 450 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 MIJ40X450-75 Is Used
Multi-Tier Pressing Stand
Trim the 450mm extend stroke by up to 75mm to press components of varying heights, relying on the 32kg vertical lift capacity to seat parts firmly.
Heavy Carton Staging
Set the exact forward position to halt large packaging carts at a loading bay, absorbing mechanical tolerances without needing custom spacers.
Is the Airtac MIJ Adjustable Cylinder MIJ40X450-75 the Right Cylinder?
The Ø40 is the largest in the series, so no larger MIJ option exists. The 75mm external stop screw is ideal for changeover jobs where you need one cylinder to cover several intermediate stops without swapping hardware. You can mount it via LB foot, FA flange or TC trunnion, but the SDB pivot-block is not available on this adjustable variant.
Keep in mind the stop screw sets the end position but does not function as a mid-stroke lock. If air pressure drops, the piston will drift, as the bumper pads only soften the impact at the stroke extremes. To maintain a vertical load during air loss, integrate an external rod lock or a pilot-operated check valve.
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 MIJ40X450-75 FAQ
The theoretical maximum force is 128.1kgf at 1.0MPa.
An external screw shortens the extend stroke by up to 75mm on-site, but the retract stroke remains full. This SKU has no magnet and cannot take CMSG/DMSG/EMSG sensors; you need the -S variant for position sensing. The stainless round-body build resists mild corrosion.
