About the Airtac MIJ Adjustable Cylinder MIJ40X200-100S
Dial in your forward end position on-site with the AirTAC MIJ40X200-100S, a round-body stainless-steel mini cylinder featuring a 100mm adjustable extend window. An external stop screw lets you shorten the forward stroke from its 200mm nominal length down to 100mm, absorbing setup tolerances and letting one part number cover multiple stop distances without swapping hardware. Retract remains full length.
The stainless barrel and rod resist mild corrosion and washdown environments, while the -S suffix equips the piston with a magnet for CMSG, DMSG, or EMSG position sensing. Because this is a Ø40 bore, it is a non-ISO-6432 round-body design. It uses fixed TPU bumper pads to decelerate the stroke end rather than an adjustable air cushion.

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 MIJ40X200-100S Is Used
Staged Diverting
Tune the 100mm extend stop to push varying carton sizes onto secondary lanes without replacing the cylinder.
Fill Head Positioning
Adjust the forward end down to 100mm to accommodate different container heights on a 628.3N-capable filling line.
Pallet Changeover
Shift the extend end on-site to handle multiple pallet widths, using the 32kg vertical lift capacity for top-flap closure.
Is the Airtac MIJ Adjustable Cylinder MIJ40X200-100S the Right Cylinder?
When sizing this unit, consider the force boundaries: if you need less push, stepping down to the Ø32 bore yields 402.2N at 0.5MPa, while this Ø40 model provides 628.3N at 0.5MPa (879.6N at 0.7MPa) as the largest available bore. The 100mm adjustment window is ideal for changeover jobs where you need to tune the extend end without machining new hard stops. Mount using LB foot, FA flange, or TC trunnion brackets, plus CA, U, R, or CM back covers—note that the SDB pivot block is not offered on this adjustable variant.
Remember that the external stop screw sets the forward end position but acts purely as a physical stop; it is not a mid-stroke lock. If air pressure drops or the valve is centered, the piston will drift and cannot hold a load. For suspended or vertical loads that must resist gravity on air loss, install 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 MIJ40X200-100S FAQ
This double-acting Ø40 bore cylinder uses a 1/4" port and a Ø16mm rod with an M12x1.25 male thread. The theoretical maximum force is 128.1kgf at 1.0MPa.
The external stop screw shortens the extend stroke by up to 100mm, giving a usable forward range of 100-200mm; retract travel remains full. The -S suffix means a piston magnet is built-in for CMSG, DMSG, or EMSG sensors. The stainless build provides mild washdown resistance.
