About the Airtac MIJ Adjustable Cylinder MIJ25X40-10S
Dial in a precise forward end position on-site with the AirTAC MIJ25X40-10S, 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 10 mm, yielding a usable 30 to 40 mm forward travel while keeping full retract. This on-site tuning absorbs mechanical tolerances and lets one part number cover several intermediate stops without swapping hardware.
The stainless barrel and rod resist mild corrosion and washdown, and the body drops directly into standard ISO 6432 mini-cylinder brackets. Because this SKU carries the -S suffix, a built-in piston magnet is ready for CMSG, DMSG or EMSG position switches.

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 MIJ25X40-10S Is Used
Staged Divert Gate
Act as a routing flap on a washdown line where the stainless build resists moisture, using the adjustable stop to set the protrusion distance for different package widths.
Carton Staging Stop
Halt incoming boxes at a packing station; the stop screw fine-tunes the fence position by up to 10 mm to compensate for guide rail wear and ensure perfect alignment.
Is the Airtac MIJ Adjustable Cylinder MIJ25X40-10S the Right Cylinder?
Choose the Ø25 when your load sits right in that middle band and you need the 10 mm extend-trim to fine-tune a clamping or staging position. The external adjuster sets the forward stop only; it is not a mid-stroke lock. If the assembly must hold a load during air loss, add an external rod lock or pilot check valve, as the piston will drift.
For mounting, you can use LB foot brackets, FA flanges, or TC trunnions, but the SDB pivot block is not available on this adjustable variant. Back cover options include CA, U, R, and CM. The 1/8" port supplies air efficiently, and the fixed TPU bumper pads decelerate the stroke end across the 30 to 800 mm/s speed range.
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 MIJ25X40-10S FAQ
The theoretical maximum force is 50 kgf at 1.0 MPa.
An external stop screw shortens the extend stroke by up to 10 mm, letting you set the forward end position without changing the cylinder; retract remains full. The -S suffix means it has a built-in piston magnet for CMSG, DMSG, or EMSG sensors.
