About the Airtac MICJ Adjustable Mini Cylinder MICJ25X75-30STC
Trim the forward stop by up to 30 mm on site without swapping hardware using the AirTAC MICJ25X75-30STC. This double-acting stainless round-body mini cylinder pairs that extend adjuster with a needle-set variable air cushion at both ends, letting you dial in the exact forward position from 45 to 75 mm while soaking up high-speed shock. The built-in piston magnet supports CMSG, DMSG and EMSG switches for precise end-of-stroke sensing.
Built to the ISO 6432 mounting interface, the Ø25 mm drop-in design pushes with 245.3 N and pulls with 206.1 N at 0.5 MPa. The stainless barrel and rod resist mild corrosion and washdown. For sizing context, this bore provides a safe working load of roughly 147 N, or about 12.5 kg of vertical lift with a 2:1 margin. It feeds through a 1/8" port and runs at speeds from 30 to 800 mm/s.

Where the Airtac MICJ Adjustable Mini Cylinder MICJ25X75-30STC Is Used
Diverter Gate Positioning
Tune the 45 to 75 mm extend stop to route mixed carton sizes on a line, relying on the 245.3 N push force to swing the gate cleanly.
Light Press Assembly
Dial in the exact 30 mm forward offset for seating clips, using the dual air cushions to prevent bounce when cycling at high speed.
Product Reject Arm
Lift roughly 12.5 kg of vertical load with a 2:1 safety margin, snapping the reject arm out fast while the needle cushion absorbs the shock.
Is the Airtac MICJ Adjustable Mini Cylinder MICJ25X75-30STC the Right Cylinder?
Step down to a Ø20 bore if your application only needs 157 N of push force at 0.5 MPa, or step up to a Ø32 bore for 402 N when moving heavier jigs. The Ø25 hits a balanced 245.3 N push at 0.5 MPa. The external stop screw and dual air cushions shine in fast set-position moves where you must tune the impact and end point on the fly. The TC trunnion mount fits standard ISO 6432 brackets, though the SDB pivot block is not offered on this adjustable variant. The -S magnet enables electronic and reed sensors.
Remember that the stop screw sets the extend end position but acts purely as a mechanical stop, not a mid-stroke lock. The air cushion only decelerates the piston near the stroke end and will not hold a load. If your setup must resist drift on air loss or a centered valve, install an external rod lock or a pilot-operated check valve.
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 MICJ Adjustable Mini Cylinder MICJ25X75-30STC FAQ
At 0.5 MPa this cylinder pushes with 245.3 N and pulls with 206.1 N. At 0.7 MPa it pushes with 343.4 N and pulls with 288.5 N. The theoretical maximum force is 50 kgf at 1.0 MPa. It uses a 1/8" air port.
An external screw shortens the extend stroke by up to 30 mm, giving a usable forward range of 45 to 75 mm, while the retract stroke remains full. Needle-set variable air cushions at both ends decelerate the piston to absorb high-speed shock. The -S suffix means it has a built-in magnet for CMSG, DMSG or EMSG sensors.
