About the Airtac MIJ Adjustable Cylinder MIJ25X200-30S
Dial in a precise forward end position on-site with the AirTAC MIJ25X200-30S, a double-acting round-body mini cylinder featuring a 30 mm extend-stroke adjustment window. An external stop screw lets you shorten the forward travel anywhere from the 200 mm maximum down to 170 mm, absorbing setup tolerances without swapping hardware. The retract stroke remains full length. Built with a stainless-steel barrel and Ø10 mm piston rod, it delivers mild corrosion resistance for washdown or humid settings.
It conforms to the ISO 6432 mounting interface for standard mini brackets and uses a 1/8" port with an M10×1.25 male rod thread. Because this SKU carries the -S suffix, a built-in piston magnet enables position sensing with CMSG, DMSG or EMSG 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 MIJ25X200-30S Is Used
Staged Package Feeding
Pushes cartons of varying widths to a downstream lane, using the 30 mm adjuster to dial in the exact 170-200 mm extend stop without reprogramming the PLC.
Tolerance Take-Up Jig
Clamps machined parts at a safe 147 N working load, letting the external screw absorb minor workpiece length variations while maintaining full retract clearance.
Is the Airtac MIJ Adjustable Cylinder MIJ25X200-30S the Right Cylinder?
When sizing this actuator, check both directions: dropping down to a Ø20 MIJ lowers the 0.5 MPa push force to 157 N, while stepping up to a Ø32 MIJ raises it to 402 N. The 30 mm external adjuster is ideal when you need one part number to cover several staged feed distances or to take up mechanical tolerances during changeover. Fixed TPU bumper pads decelerate the stroke end across the 30-800 mm/s speed range.
Keep in mind the stop screw sets the end position but acts purely as a mechanical stop, not a mid-stroke lock. The piston will drift if air pressure is lost, so fit an external rod lock or pilot check valve for holding suspended loads. For mounting, you can use LB foot, FA flange or TC trunnion brackets along with CA, U, R or CM back covers, but note the SDB pivot block is not available 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 MIJ25X200-30S FAQ
This Ø25 mm bore cylinder uses a 1/8" air port. The theoretical maximum force is 50 kgf at 1.0 MPa.
An external stop screw shortens the extend stroke by up to 30 mm on-site (usable forward travel 170-200 mm), while retract remains full. The -S suffix means a piston magnet is built in for CMSG, DMSG or EMSG sensors. The stainless build resists mild corrosion.
