About the Airtac MIJ Adjustable Cylinder MIJ25X160-20
Trim the forward travel by up to 20 mm on site with the AirTAC MIJ25X160-20, a double-acting round-body mini cylinder built around a stainless-steel barrel and Ø10 mm rod for mild washdown resistance. The external stop screw lets you dial in the exact extend end position between 140 and 160 mm without swapping parts, while the retract stroke remains full length. It conforms to the ISO 6432 mounting interface for standard mini brackets and uses a 1/8" port with an M10x1.25 male rod thread.
Deceleration relies on fixed TPU bumper pads, and because this specific SKU lacks the -S magnet, it cannot host 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 MIJ25X160-20 Is Used
Variable Depth Sealing
Accommodate different box lengths on a sealing head without changing cylinders; the 20 mm stop screw trims the forward jaw position while the stainless rod shrugs off washdown.
Multi-Stop Tool Change
Use one 25 mm bore actuator to drive a tooling plate to slightly different extended endpoints across product families, taking up setup tolerances on the fly.
Is the Airtac MIJ Adjustable Cylinder MIJ25X160-20 the Right Cylinder?
When sizing this unit, stepping down to a 20 mm bore drops the 0.5 MPa push force to 157.0 N, whereas moving up to a 32 mm bore raises it to 402.2 N. The 20 mm adjustment window is ideal for taking up mechanical tolerances or matching multiple stop points in a changeover fixture using one part number. Remember that the stop screw only sets the extend end position; it is not a mid-stroke lock. The piston will drift on air loss, so fit an external rod lock or pilot check valve if you need to hold a suspended load. Mount via LB foot, FA flange or TC trunnion, noting the SDB pivot block is not offered 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 MIJ25X160-20 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 20 mm on site, giving a usable forward range of 140-160 mm; the retract stroke remains full. This SKU has no magnet, so it cannot accept CMSG, DMSG or EMSG sensors. You would need the -S variant for position sensing.
