About the Airtac MIJ Adjustable Cylinder MIJ25X175-20S
Dial in a precise forward end position on the fly with the AirTAC MIJ25X175-20S, a round-body stainless steel mini cylinder built for double-acting service. An external stop screw lets you shorten the extend stroke by up to 20 mm on site, yielding a usable forward travel of 155 to 175 mm without changing the physical unit. Because the adjuster trims only the extend end, the retract stroke remains full length.
The stainless barrel and piston rod resist mild corrosion and washdown environments. It conforms to the ISO 6432 mounting interface for mini cylinders, and the -S suffix means a piston magnet is present for CMSG, DMSG or EMSG sensors. The 1/8" port and fixed TPU bumper pads handle rapid 30-800 mm/s cycling.

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 MIJ25X175-20S Is Used
Variable Stroke Sealing
Dial the forward stop down from 175 mm to press carton flaps of varying heights, using the fixed TPU bumpers to soften the end impact without crushing the board.
Tool Changeover Stops
Swap product runs faster by turning the external screw to set a new 155 mm forward position for a machining head, avoiding the need to physically replace the cylinder.
Is the Airtac MIJ Adjustable Cylinder MIJ25X175-20S the Right Cylinder?
The 20 mm external stop nut is invaluable for absorbing mechanical tolerances or staging a part feed, letting one SKU cover several intermediate stops. Remember that the stop screw sets the end position but acts as no mid-stroke lock; the piston will drift on air loss, so fit an external rod lock or pilot check valve for held loads. Mounting options include LB foot, FA flange and TC trunnion (SDB is unavailable on this adjustable variant), and the integrated magnet supports position sensing.
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 MIJ25X175-20S FAQ
This double-acting cylinder uses a 1/8" port and a Ø10 mm rod with an M10x1.25 male thread. At 0.5 MPa it pushes 245.3 N and pulls 206.1 N. At 0.7 MPa it pushes 343.4 N and pulls 288.5 N. The theoretical maximum force is 50 kgf at 1.0 MPa.
The external stop screw shortens the extend stroke by up to 20 mm, letting you set the forward end position between 155 and 175 mm; the retract stroke remains full. The -S suffix indicates a built-in piston magnet for CMSG, DMSG or EMSG sensors. The stainless build resists mild corrosion, and fixed TPU bumpers decelerate the stroke ends.
