About the Airtac MIJ Adjustable Cylinder MIJ25X80-50S
Dial in a precise forward end position on the fly with the AirTAC MIJ25X80-50S, a double-acting round-body mini cylinder built with a stainless-steel barrel and rod for mild washdown resistance. An external stop screw lets you shorten the extend stroke by up to 50 mm on-site, yielding a usable 30-80 mm forward travel without swapping parts. Retract remains at the full 80 mm.
The 1/8" port and M10x1.25 male rod thread provide robust connections. Because this SKU carries the -S suffix, a built-in piston magnet enables CMSG, DMSG, or EMSG position sensing.

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 MIJ25X80-50S Is Used
Tolerance Take-Up Press
Dial the forward stroke back from 80 mm to seat a part precisely against a fixture, absorbing machining variances without reprogramming the PLC.
Staged Feed Ejector
Set a specific extend endpoint to push 12.5 kg boxes into a wrapping station, adjusting the stop screw as product thickness varies between runs.
Is the Airtac MIJ Adjustable Cylinder MIJ25X80-50S the Right Cylinder?
When sizing this 25 mm bore, stepping down to a 20 mm MIJ drops the 0.5 MPa push force to 157.0 N, while stepping up to a 32 mm bore raises it to 402.2 N. The 50 mm adjustment window is ideal for taking up mechanical tolerances or staging feeds across changeover jobs. Mount via LB foot, FA flange, or TC trunnion, as the SDB pivot block is unavailable for this adjustable variant.
Bear in mind the stop screw sets the end position but acts as no mid-stroke lock. If air pressure drops, the piston will drift; for load holding, install an external rod lock or pilot check valve. Fixed TPU bumper pads decelerate the stroke ends across the 30-800 mm/s speed range.
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 MIJ25X80-50S FAQ
The air port is 1/8" and the male rod thread is M10x1.25.
The external stop screw shortens the extend stroke by up to 50 mm on-site, setting the forward end position without affecting the full 80 mm retract. The -S suffix means a magnet is built into the piston, allowing CMSG, DMSG, or EMSG sensors to detect position.
