About the Airtac MIJ Adjustable Cylinder MIJ25X70-30S
Trimming the forward end by up to 30 mm on site, the AirTAC MIJ25X70-30S lets you tune the extend position from 40 to 70 mm without swapping parts. This double-acting round-body mini cylinder houses a Ø10 mm piston rod and uses a 1/8" port.
Built with a stainless-steel barrel and rod, it resists mild corrosion and handles washdowns. The -S suffix means a piston magnet is included for CMSG, DMSG or 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).

Is the Airtac MIJ Adjustable Cylinder MIJ25X70-30S the Right Cylinder?
For lighter jobs, the MIJ20 bore pushes 157.0 N at 0.5 MPa, while stepping up to the MIJ32 yields 402.2 N if you need more force. The 30 mm adjustment window here is ideal for taking up mechanical tolerances during setup. It uses the ISO 6432 mounting interface, but the SDB pivot block is not offered on this adjustable variant.
This cylinder does not hold a load on air loss; the piston drifts, and the fixed TPU bumper pads only soften the stroke end. Use an external rod lock or pilot check valve for held loads. Speeds run 30-800 mm/s.
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 MIJ25X70-30S FAQ
It has a 1/8" port and a male M10x1.25 rod thread. At 0.5 MPa it pushes 245.3 N and pulls 206.1 N. At 0.7 MPa it pushes 343.4 N and pulls 288.5 N. The theoretical maximum force is 50 kgf at 1.0 MPa.
An external stop screw shortens the extend stroke by up to 30 mm; the retract stroke remains full. The -S suffix indicates a built-in piston magnet for CMSG, DMSG or EMSG sensors. The stop screw sets the end position but is not a mid-stroke lock.
