About the Airtac MIJ Adjustable Cylinder MIJ25X30-20
Dial in your forward end position on-site with the AirTAC MIJ25X30-20, a round-body stainless steel mini cylinder that lets an external stop screw shorten the extend stroke by up to 20 mm. Retract travel remains full, while the forward stop trims the usable extend down to 10 mm.
Built with a stainless barrel and piston rod for mild corrosion and washdown resistance, this Ø25 bore unit conforms to the ISO 6432 mounting interface for standard mini brackets. It features a 1/8" port, an M10x1.25 male rod thread, and fixed TPU bumper pads to decelerate the stroke end. Because this SKU lacks the -S magnet option, it cannot accept CMSG, DMSG, or EMSG sensors.

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 MIJ25X30-20 Is Used
Precision Feeder Stops
Trim the extend stroke up to 20 mm to dial in the exact contact point on a moving strip, absorbing feeder tolerance without remachining hard stops.
Changeover Diverter Arms
Rapidly reconfigure a conveyor routing gate for different carton widths by turning the external stop screw to set the forward position on the fly.
Is the Airtac MIJ Adjustable Cylinder MIJ25X30-20 the Right Cylinder?
The integrated adjuster is ideal for taking up mechanical tolerances or covering multiple stop positions from a single part number. Remember that the stop screw sets the end position but acts as no mid-stroke lock; the piston will drift on air loss, so add an external rod lock or pilot check valve for held loads. Mount via LB foot, FA flange, or TC trunnion (SDB pivot-block is not available 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 MIJ25X30-20 FAQ
This Ø25 mm bore cylinder uses a 1/8" port and an M10x1.25 male rod thread. The theoretical maximum force is 50 kgf at 1.0 MPa.
An external stop screw shortens the extend stroke by up to 20 mm on-site, letting you set the forward end position without swapping the cylinder; retract remains full stroke. This specific SKU has no magnet, so it cannot accept CMSG, DMSG, or EMSG switches—you would need the -S variant for sensing.
