About the Airtac MIJ Adjustable Cylinder MIJ40X500-100
Dial in a precise forward end position on-site with the AirTAC MIJ40X500-100, a round-body stainless mini cylinder featuring a 100mm adjustable extend window. An external stop screw lets you trim the forward stroke from 400 to 500mm, absorbing setup tolerances without changing the part number.
Built with a riveted stainless-steel barrel and a Ø16mm piston rod, it handles mild washdown environments and uses a 1/4" port with an M12x1.25 male rod thread. As a larger Ø40 bore, it is a non-ISO-6432 round-body design. Fixed TPU bumper pads decelerate the stroke end, and because this specific SKU lacks the -S magnet, 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 MIJ40X500-100 Is Used
Heavy Carton Staging
Index large packaging cartons by trimming the forward stroke to absorb mechanical tolerances, ensuring positive contact without crushing the load.
Is the Airtac MIJ Adjustable Cylinder MIJ40X500-100 the Right Cylinder?
The 100mm adjuster is ideal for staging feeds or taking up mechanical tolerance during changeover. Mount via LB foot, FA flange, or TC trunnion, noting the SDB pivot block is not offered on this adjustable variant.
The external screw sets the extend endpoint but acts purely as a stop, not a mid-stroke lock. The piston will drift if air pressure drops, as the TPU bumpers only soften the end-of-stroke impact. To sustain a vertical load during air loss, fit an external rod lock or pilot 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 MIJ40X500-100 FAQ
The air port is 1/4" and the male rod thread is M12x1.25.
An external stop screw shortens the extend stroke by up to 100mm on-site, leaving retract at the full 500mm. The screw is only an end-position stop, not a mid-stroke lock, so the piston drifts on air loss. This SKU has no magnet and cannot take sensors; the -S variant is required for CMSG/DMSG/EMSG switches.
