About the Airtac MIJ Adjustable Cylinder MIJ25X250-75S
Dial in a precise forward end position on-site with the AirTAC MIJ25X250-75S, a double-acting round-body mini cylinder built with a stainless-steel barrel and rod for mild corrosion resistance. An external stop screw lets you shorten the extend stroke by up to 75 mm, yielding a usable forward travel of 175 to 250 mm without swapping parts. Retract travel remains fixed at the full 250 mm. The Ø25 bore conforms to the ISO 6432 mounting interface, dropping directly into standard mini brackets and clevises.
The 1/8" port and M10x1.25 male rod thread handle the airflow and linkage for this force class. Because this SKU includes the -S magnet, it is fully ready for CMSG, DMSG, or EMSG position sensing. Fixed TPU bumper pads decelerate the stroke ends across the 30-800 mm/s speed range.

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 MIJ25X250-75S Is Used
Staged Diverting
Trim the extend stroke by up to 75 mm to push varying carton sizes onto secondary lines without changing the cylinder mount.
Adjustable Sealing Press
Set the exact forward crush distance for different package heights, relying on the stainless build for washdown environments.
Is the Airtac MIJ Adjustable Cylinder MIJ25X250-75S the Right Cylinder?
The 75 mm adjustment window is ideal for taking up mechanical tolerances or staging feeds during changeovers, letting one part number cover several intermediate stops. Mounting options include LB foot, FA flange, and TC trunnion brackets, plus CA, U, R, or CM back covers, though the SDB pivot block is not offered on this adjustable variant. Remember that the stop screw only trims the extend end position; it is not a mid-stroke lock. The cylinder will drift on air loss, so fit an external rod lock or pilot check valve if you need to hold a suspended load.
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 MIJ25X250-75S FAQ
This 25 mm bore cylinder uses a 1/8" port. At 0.5 MPa it pushes with 245.3 N and pulls with 206.1 N. At 0.7 MPa the push is 343.4 N and pull is 288.5 N. The theoretical maximum force is 50 kgf at 1.0 MPa.
An external screw shortens the extend stroke by up to 75 mm on-site, setting the exact forward end position while retract remains full. The included -S magnet enables CMSG, DMSG, or EMSG sensors for position detection. The stainless construction provides mild washdown resistance.
