About the Airtac MIJ Adjustable Cylinder MIJ25X50-30STC
Dial in a precise forward end position on the fly with the AirTAC MIJ25X50-30STC, a double-acting round-body mini cylinder built with a stainless-steel barrel and piston rod. An external stop screw lets you shorten the extend stroke by up to 30 mm on site, giving a usable forward travel of 20 to 50 mm without swapping parts. Retract travel remains the full 50 mm. The built-in magnet (-S) supports CMSG, DMSG, and EMSG position switches.
It features fixed TPU bumper pads to decelerate the stroke ends and uses a 1/8" port with a Ø10 mm rod. The stop screw sets the forward endpoint but does not lock the piston mid-stroke.

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 MIJ25X50-30STC Is Used
Staged Feed Diverter
Trim the extend stroke by up to 30 mm to alter a diverter gate angle on the fly, accommodating different carton widths on a packaging line without changing hardware.
Tolerance Take-Up Stop
Use the adjustable forward stop to absorb mechanical variances in machined parts, providing a soft, repeatable end position for a 12.5 kg workpiece.
Is the Airtac MIJ Adjustable Cylinder MIJ25X50-30STC the Right Cylinder?
When sizing this 25 mm bore, step down to a 20 mm bore if your push needs are under 157 N at 0.5 MPa, or step up to a 32 mm bore for 402.2 N when heavier forces are required. The 30 mm adjustment window is ideal for taking up mechanical tolerances during setup or covering several stop positions with a single part number. A TC trunnion mount is included, though the SDB pivot block is not offered on this adjustable variant.
Because this is a double-acting air cylinder, it will drift if air pressure is lost or the valve is centered; the stop screw and bumpers only manage the end of travel, not hold a load. Use an external rod lock or pilot check valve if you need to maintain position. Select CMSG, DMSG, or EMSG sensors to pair with the internal magnet.
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 MIJ25X50-30STC FAQ
The theoretical maximum force is 50 kgf at 1.0 MPa.
An external stop screw shortens the extend stroke by up to 30 mm on site, allowing a usable forward travel of 20 to 50 mm, while retract remains the full 50 mm. The -S suffix indicates a built-in piston magnet for use with CMSG, DMSG, or EMSG sensors.
