About the Airtac MIJ Adjustable Cylinder MIJ25X225-20
Dial in a precise forward end position on-site with the AirTAC MIJ25X225-20, a double-acting round-body mini cylinder featuring a 20 mm extend-stroke adjustment window. An external stop screw lets you trim the forward travel down from the 225 mm nominal maximum to 205 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 withstands mild corrosion and washdown environments.
This Ø25 mm bore conforms to the ISO 6432 mounting interface for straightforward bracket interchangeability. Pneumatic connection is via a 1/8" port. Fixed TPU bumper pads decelerate the stroke ends across the 30-800 mm/s speed range. Note this SKU lacks a magnet and cannot host CMSG/DMSG/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 MIJ25X225-20 Is Used
Staged Diverter Gate
Trim the 225 mm extend stroke by up to 20 mm to tune a diverter gate on a packaging line, ensuring precise product routing without re-mounting hardware.
Tolerance Take-Up Stop
Absorb cumulative fixture tolerances in a machining cell by dialing in the exact forward stop position, relying on the stainless build for mild coolant splash.
Is the Airtac MIJ Adjustable Cylinder MIJ25X225-20 the Right Cylinder?
The 20 mm external adjuster is ideal for changeover jobs where you need one cylinder body to cover several slightly different forward stops. Mount using LB foot, FA flange, or TC trunnion brackets (SDB pivot blocks are not available on this adjustable variant). Back cover options include CA, U, R, and CM.
Because this is a double-acting air cylinder, it will drift and cannot hold a load if air pressure drops or the valve centers. The stop screw sets the end position but functions purely as a mechanical stop, not a mid-stroke lock or brake. To maintain vertical loads safely, integrate an external rod lock or a pilot-operated check valve into your circuit.
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 MIJ25X225-20 FAQ
This Ø25 mm cylinder uses a 1/8" port and an M10x1.25 male rod thread. The theoretical maximum force is 50 kgf at 1.0 MPa.
An external stop screw shortens the extend stroke by up to 20 mm on-site (usable range 205-225 mm); the retract stroke remains full. This SKU has no magnet and cannot accept CMSG/DMSG/EMSG sensors. For position sensing, you need the -S variant. Fixed TPU bumpers decelerate the stroke ends.
