About the Airtac MIJ Adjustable Cylinder MIJ16X25-20S
Dial in a precise forward end position on the fly with this stainless steel round-body mini cylinder. An external stop screw lets you trim the extend stroke by up to 20 mm directly on the machine, allowing one part number to cover several forward stops without swapping hardware. Retract remains a full 25 mm stroke, and the screw sets the end position rather than acting as a mid-stroke lock.
Built to the ISO 6432 mounting interface for standard mini brackets, the Ø16 bore uses an M5×0.8 port and a Ø6 mm piston rod with an M6x1.0 male thread. The -S suffix means a piston magnet is included for CMSG, DMSG or EMSG sensors, while fixed TPU bumper pads absorb end-of-stroke impact.

Specifications follow the official AirTAC MI/MIC (ISO 6432) datasheet. Barrel & rod: stainless steel (round-body, riveted construction). Thread options: PT (blank) / G.
Theoretical Output Force (Ø16mm)
| Pressure | Force (both ways) |
|---|---|
| 0.5 MPa | 86 N |
| 0.7 MPa | 121 N |
| Max (@1.0 MPa) | 18 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 MIJ16X25-20S Is Used
Staged Feed Ejection
Set different forward end positions for a changeover job without changing the cylinder, using the adjustable stop to push varied lightweight products off a conveyor line.
Is the Airtac MIJ Adjustable Cylinder MIJ16X25-20S the Right Cylinder?
This Ø16 model sits comfortably in the middle for moderate tasks. The 20 mm adjustment window is ideal for taking up mechanical tolerances or staggering part feeds during setup. Remember that a standard cylinder drifts on air loss; the stop screw sets the end position but does not brake the piston, so fit an external rod lock or pilot check valve if you must hold a suspended load.
Mounting options include LB foot brackets, FA flanges and TC trunnions, but the SDB pivot block is not available on this adjustable variant. Because this SKU carries the -S magnet, you can directly mount CMSG, DMSG or EMSG switches for position sensing.
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 MIJ16X25-20S FAQ
The theoretical maximum force is 20.5 kgf at 1.0 MPa.
An external screw shortens the extend stroke by up to 20 mm on-site, letting you dial in the forward end position without affecting the full retract stroke. The -S suffix indicates a built-in piston magnet for use with CMSG, DMSG or EMSG sensors.
