About the Airtac MIJ Adjustable Cylinder MIJ25X160-40
Dial in a precise forward end position on-site with the AirTAC MIJ25X160-40, a round-body stainless steel mini cylinder featuring a 40 mm extend-stroke adjustment window. An external stop screw lets you shorten the forward stroke from its 160 mm nominal length down to 120 mm, absorbing setup tolerances without changing the cylinder. The retract stroke remains full length. Built with a stainless barrel and piston rod, it handles mild washdown environments and conforms to the ISO 6432 mounting interface for standard mini brackets.
It uses a 1/8" port 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 MIJ25X160-40 Is Used
Staged Feed Diverter
Pushes cartons at 245 N while the 40 mm extend adjuster dials in the exact deflection angle for different box sizes on the line.
Variable Depth Sealing
Sets the forward crimp position for mixed packaging depths without swapping cylinders, using the 1/8" port for rapid actuation.
Adjustable Stop Gate
Handles 12.5 kg vertical lift loads and fine-tunes the gate open position on the fly to accommodate varying pallet heights.
Is the Airtac MIJ Adjustable Cylinder MIJ25X160-40 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 N, while moving up to a 32 mm bore increases it to 402 N. The 40 mm external adjuster is ideal for changeover jobs where one part number must cover several staged stops, letting you fine-tune the extend end without swapping hardware. Retract is fixed at the full 160 mm.
The stop screw sets the end position but is not a mid-stroke lock; the piston will drift on air loss, so add an external rod lock or pilot check valve for holding loads. Mount using LB foot, FA flange, or TC trunnion brackets (SDB is unavailable on this adjustable variant). Back cover options include CA, U, R, and CM.
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 MIJ25X160-40 FAQ
The theoretical max force is 50 kgf at 1.0 MPa. The air port is 1/8" and the male rod thread is M10x1.25.
An external stop screw shortens the extend stroke by up to 40 mm on-site (usable extend 120-160 mm); the retract stroke remains full. This SKU has no magnet, so it cannot take CMSG/DMSG/EMSG sensors. The stainless build resists mild corrosion.
