About the Airtac MIJ Adjustable Cylinder MIJ25X100-100S
Dial in a precise forward end position on-site with the AirTAC MIJ25X100-100S, a round-body stainless steel mini cylinder featuring a 100mm adjustable extend window. A external stop screw lets you shorten the forward stroke by up to 100mm without swapping parts, while the retract stroke remains full length.
Built with a riveted stainless-steel barrel and Ø10 mm piston rod, this double-acting unit resists mild corrosion and washdown environments. It uses the ISO 6432 mounting interface for standard mini brackets and includes a built-in magnet (-S) for CMSG, DMSG or EMSG sensors. The 1/8" port and fixed TPU bumper pads ensure reliable operation across 30-800 mm/s.

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 MIJ25X100-100S Is Used
Variable Stroke Tucking
Adjust the forward stroke on the fly for different carton depths without changing cylinders, leveraging the 12.5kg vertical lift capacity for flap folding.
Tolerance Take-Up Jigs
Fine-tune the forward end position to compensate for part variance in clamping stations, ensuring consistent contact without over-stroking the workpiece.
Is the Airtac MIJ Adjustable Cylinder MIJ25X100-100S the Right Cylinder?
When sizing this 25 mm bore, moving down to a 20 mm MIJ drops the 0.5 MPa push force to 157 N, while stepping up to a 32 mm bore raises it to 402 N. The 100mm adjustment window is ideal for taking up mechanical tolerances or staging feeds across changeover jobs, letting one SKU cover several intermediate stops. Mount using LB foot, FA flange or TC trunnion brackets (the SDB pivot block is not offered on this adjustable variant), and select the -S magnet version to enable position sensing.
Remember that the stop screw sets the extend end position but acts purely as a physical stop, not a mid-stroke lock. The piston will drift if air pressure is lost, and the fixed TPU bumpers only decelerate the stroke end rather than holding the load. To maintain position during an air failure, install an external rod lock or a pilot-operated check valve in the system.
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 MIJ25X100-100S FAQ
This 25 mm bore cylinder uses a 1/8" air port and a male M10x1.25 rod thread. The theoretical maximum force is 50 kgf at 1.0 MPa.
An external stop screw shortens the extend stroke by up to 100mm on-site, allowing you to set the exact forward end position while the retract stroke remains full. The -S suffix indicates a built-in piston magnet for use with CMSG, DMSG or EMSG sensors. The cylinder uses fixed TPU bumper pads, not an adjustable air cushion.
