About the Airtac MIJ Adjustable Cylinder MIJ40X25-10S
Trimming the forward end by up to 10 mm on site, this stainless round-body mini cylinder lets you fine-tune the 25 mm extend stroke without changing parts. The external stop screw sets the forward position while retract remains full, making it ideal for tolerance take-up and rapid changeovers.
The stainless barrel and rod resist mild corrosion and washdown environments. Because this SKU includes the -S magnet, it supports CMSG, DMSG, and EMSG sensors for position detection.

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 MIJ40X25-10S Is Used
Heavy Clamping Stop
Dial in the exact 15 to 25 mm forward clamp position on heavy fixtures, using the stop screw to take up material tolerances without reworking the line.
Washdown Feed Pusher
Push packaging materials into position in damp environments, leveraging the stainless build and tuning the 10 mm adjuster to match various box depths.
Is the Airtac MIJ Adjustable Cylinder MIJ40X25-10S the Right Cylinder?
The 10 mm adjustment window is invaluable for dialing in exact forward stops during setup.
Note that the stop screw only sets the end position; it is not a mid-stroke lock. The piston will drift on air loss, so add an external rod lock or pilot check valve for holding loads. Mount via LB foot, FA flange, or TC trunnion, as the SDB pivot block is not offered on this adjustable variant.
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 MIJ40X25-10S FAQ
The theoretical maximum force is 128.1 kgf at 1.0 MPa.
An external screw shortens the extend stroke by up to 10 mm, giving a usable 15 to 25 mm forward range, while retract stays full. The -S suffix means a piston magnet is built in for CMSG, DMSG, or EMSG sensors.
