About the Airtac MIJ Adjustable Cylinder MIJ25X50-10S
Dial in exact forward end positions on-site with the AirTAC MIJ25X50-10S, a round-body stainless steel mini cylinder featuring a 10 mm extend-stroke adjustment window. An external stop screw lets you shorten the forward stroke from its 50 mm nominal maximum down to 40 mm, absorbing setup tolerances without swapping parts. The retract stroke remains full length. Built with a riveted stainless barrel and rod, it handles mild washdowns and corrosion risks. Because this SKU includes the -S magnet, it is ready for CMSG, DMSG, or EMSG position switches.
It conforms to the ISO 6432 mounting interface for easy bracket drops, uses a 1/8" port, and relies on fixed TPU bumper pads to decelerate the stroke end. The stop screw sets the end position but is not a mid-stroke lock.

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 (Ø25mm)
| Pressure | Force (both ways) |
|---|---|
| 0.5 MPa | 206 N |
| 0.7 MPa | 289 N |
| Max (@1.0 MPa) | 42 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 MIJ25X50-10S Is Used
Sealing Head Stop
Sets a precise forward end position for a 12.5 kg vertical lift, absorbing mechanical tolerances so the sealing jaw contacts the package perfectly.
Changeover Stop Gauge
Acts as an adjustable hard stop for machining fixtures, trimming the extend stroke by up to 10 mm to accommodate different raw part lengths rapidly.
Is the Airtac MIJ Adjustable Cylinder MIJ25X50-10S the Right Cylinder?
When sizing this 25 mm bore, compare it directly against adjacent options. Stepping down to a 20 mm MIJ drops the 0.5 MPa push force to 157 N, while moving up to a 32 mm bore increases it to 402 N. The external screw trims the forward end only, letting one part number cover several slightly different stop points.
Remember that a standard cylinder does not hold position on air loss; the piston drifts, and the TPU bumper only softens the stroke end. For a locked load, install an external rod lock or pilot check valve. Mount this actuator using LB foot, FA flange, or TC trunnion brackets (the SDB pivot block is not available on this adjustable variant). The built-in -S magnet supports CMSG, DMSG, and EMSG sensors.
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 MIJ25X50-10S FAQ
This 25 mm bore cylinder uses a 1/8" port. The theoretical maximum force is 50 kgf at 1.0 MPa.
An external stop screw shortens the extend stroke by up to 10 mm on-site, setting the forward end position without affecting the full retract stroke. The -S suffix means it has a built-in piston magnet for CMSG, DMSG, or EMSG sensors. Fixed TPU bumpers decelerate the stroke ends.
