About the Airtac MIJ Adjustable Cylinder MIJ25X150-40S
Dial in a precise forward end position on-site with the AirTAC MIJ25X150-40S, a double-acting round-body mini cylinder featuring a 40mm adjustable extend window. An external stop screw lets you shorten the forward stroke from its 150mm nominal length down to 110mm, absorbing setup tolerances without swapping hardware. The retract stroke remains full length. Built with a stainless-steel barrel and Ø10mm rod, it handles mild corrosion and washdown environments while conforming to the ISO 6432 mounting interface for standard mini brackets.
The 1/8" port feeds air to drive the piston at 30-800 mm/s, decelerated at the ends by fixed TPU bumper pads. Because this SKU includes the -S magnet, it is ready to accept CMSG, DMSG, or EMSG sensors for position detection.

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 MIJ25X150-40S Is Used
Staged Part Ejection
Use the 40mm extend adjustment to tune the push-off distance for varying product lengths on a conveyor, ensuring gentle transfers without re-specifying the cylinder.
Adjustable Stop Pressing
Apply the precise forward end stop for light pressing and seating tasks, using the fixed TPU bumpers to absorb the impact of the 12.5 kg load at the end of travel.
Is the Airtac MIJ Adjustable Cylinder MIJ25X150-40S the Right Cylinder?
The 40mm external stop screw is ideal for machines needing staged feeds or frequent changeovers, letting one part number cover several stopping points. 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.
Mounting options include LB foot brackets, FA flanges, and TC trunnions, but the SDB pivot block is not available on this adjustable variant. Back covers include CA, U, R, and CM styles. The built-in -S magnet enables direct mounting of CMSG, DMSG, or EMSG switches along the stainless barrel for exact stroke confirmation.
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 MIJ25X150-40S FAQ
This Ø25 bore cylinder features a 1/8" port and a male M10x1.25 rod thread. The theoretical maximum force is 50 kgf at 1.0 MPa.
An external stop screw shortens the extend stroke by up to 40mm on-site, giving a usable forward range of 110-150mm; the retract stroke remains full length. The included -S piston magnet allows CMSG, DMSG, and EMSG sensors to detect position. Fixed TPU bumpers decelerate the stroke ends.
