About the Airtac MIJ Adjustable Cylinder MIJ25X100-40S
Dial in your forward end position on the fly with the AirTAC MIJ25X100-40S, a double-acting round-body mini cylinder featuring an external stop screw that shortens the extend stroke by up to 40 mm. This on-site adjustability lets you cover multiple stop distances with a single unit, taking up mechanical tolerances during setup without swapping cylinders. The retract stroke remains full length.
Conforming to the ISO 6432 mounting interface for mini cylinders, this Ø25 bore unit drops directly into standard brackets and clevises. It features a 1/8" air port, an M10x1.25 male rod thread, and a built-in piston magnet (-S) for position sensing. Fixed TPU bumper pads decelerate the stroke ends, operating reliably at speeds of 30-800 mm/s.

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 MIJ25X100-40S Is Used
Staged Part Feeding
Pushes diversified components down a line, using the 40 mm extend adjustment to dial in the exact push distance for each product changeover without replacing hardware.
Tolerance Take-Up Jig
Compensates for cumulative mechanical tolerances in an assembly fixture by fine-tuning the extend end position, safely moving about 12.5 kg of vertical load.
Is the Airtac MIJ Adjustable Cylinder MIJ25X100-40S the Right Cylinder?
The 40 mm adjustment window is highly useful for changeover jobs where a part is modified slightly, allowing you to trim the extend end without machining new hard stops. Retract travel stays fixed at the full 100 mm.
Because the -S magnet is present, you can mount CMSG, DMSG, or EMSG switches for end-of-stroke confirmation. Mounting options include LB foot, FA flange, and TC trunnion styles, but note that the SDB pivot block is not offered on this adjustable variant. Keep in mind the stop screw only sets the forward end position; it is not a mid-stroke lock, and the cylinder will drift on air loss. Use an external rod lock or pilot check valve if you must hold a load vertically.
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 MIJ25X100-40S FAQ
This Ø25 bore cylinder uses a 1/8" air port. At 0.7 MPa, push increases to 343.4 N and pull to 288.5 N. The theoretical maximum force is 50 kgf at 1.0 MPa.
An external stop screw shortens the extend stroke by up to 40 mm on site, letting you set the exact forward end position while retract remains full. The -S suffix means a piston magnet is built-in, allowing you to fit CMSG, DMSG, or EMSG sensors. The stainless steel build resists mild corrosion.
