About the Airtac MIJ Adjustable Cylinder MIJ25X90-50S
Dial in your forward end position on-site with the AirTAC MIJ25X90-50S, a stainless-steel round-body mini cylinder featuring a 50 mm extend-stroke adjustment window. An external stop screw lets you shorten the forward travel anywhere from the 90 mm nominal down to 40 mm, absorbing setup tolerances without swapping hardware. Retract travel remains full length. The Ø25 bore conforms to the ISO 6432 mounting interface, dropping directly into standard mini brackets and clevises.
The included -S piston magnet supports CMSG, DMSG and EMSG sensors, and fixed TPU bumper pads decelerate the stroke ends.

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)

| 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 MIJ25X90-50S Is Used
Staged Diverter Pusher
Use the 50 mm on-site stroke adjustment to tune the push distance of packages on a conveyor line, adapting to varying box widths without changing the cylinder.
Variable Depth Carton Sealer
Fine-tune the extend stroke down to 40 mm to press carton flaps of varying depths, using the built-in magnet for position confirmation during the packaging cycle.
Is the Airtac MIJ Adjustable Cylinder MIJ25X90-50S the Right Cylinder?
The Ø25 hits a balanced 245.3 N, making it ideal for mid-range tasks. The 50 mm external adjuster is perfect for changeover jobs where multiple stop positions are needed from a single part number. Air ports are 1/8" and the male rod thread is M10x1.25.
Mount using LB foot, FA flange or TC trunnion brackets, as the SDB pivot block is not available for this adjustable variant. Remember that the stop screw only sets the 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 MIJ25X90-50S FAQ
The theoretical maximum force is 50 kgf at 1.0 MPa.
An external stop screw shortens the extend stroke by up to 50 mm on-site, but retract remains full length. The -S suffix means it has a built-in piston magnet for CMSG, DMSG or EMSG sensors. Fixed TPU bumpers decelerate the stroke ends.
