Airtac MICJ Adjustable Mini Cylinder MICJ25X60-30S
The AirTAC Airtac MICJ Adjustable Mini Cylinder MICJ25X60-30S is a genuine double acting, adjustable stroke + cushion round-body mini air cylinder with a Ø25mm bore and 60mm stroke, 1/8" air ports and a stainless-steel barrel and rod for mildly corrosive environments. Its ISO 6432 mounting interface makes it a compact drop-in for standard mini-cylinder fixtures.

About the Airtac MICJ Adjustable Mini Cylinder MICJ25X60-30S
Dial in a precise forward stop on-site with the AirTAC MICJ25X60-30S, a stainless-steel round-body mini cylinder that lets you shorten the extend stroke by up to 30 mm via an external screw. This 25 mm bore, double-acting actuator delivers 245.3 N of push force at 0.5 MPa, while a needle-adjustable air cushion at both ends absorbs high-speed impact. It conforms to the ISO 6432 mounting interface for standard mini brackets and uses a 1/8" port.
Because this SKU includes the -S magnet, it is fully ready for CMSG, DMSG, or EMSG position sensing. The stainless barrel and rod resist mild corrosion and washdown environments. With a safe working load around 147 N (roughly 60% of the 0.5 MPa push figure), it moves about 12.5 kg vertically with a 2:1 safety margin. Note that the stop screw sets the end position but does not lock the piston mid-stroke.

Where the Airtac MICJ Adjustable Mini Cylinder MICJ25X60-30S Is Used
Divert Gate Tuning
Adjust the 30 mm extend stop to perfectly set a divert gate's open angle without machining spacers, letting the dual cushion absorb the 245.3 N impact at high cycle rates.
Variable Depth Flap Fold
Shift the extend endpoint on the fly for different carton depths, using the -S magnet to confirm the folded position via a DMSG sensor.
Light Press Fit
Press a 12 kg sub-assembly into place with a safe 147 N working load, relying on the needle cushion to prevent harsh end-of-stroke shock.
Is the Airtac MICJ Adjustable Mini Cylinder MICJ25X60-30S the Right Cylinder?
This 25 mm bore strikes a solid middle ground: stepping down to a 20 mm MICJ drops the 0.5 MPa push force to 157 N, while moving up to a 32 mm bore increases it to 402 N. Choose this 60 mm nominal stroke with the 30 mm extend adjuster when you need to tune the forward position without swapping hardware, and rely on the dual air cushions to smooth out fast 30-800 mm/s moves. The -S magnet enables electronic or reed sensors.
For mounting, you can use LB foot, FA flange, or TC trunnion brackets, plus CA, U, R, or CM back covers, but the SDB pivot block is not offered on this adjustable variant. Remember that air pressure drives motion but does not hold the load—if air is lost, the piston drifts. Use an external rod lock or pilot check valve if you need to maintain vertical position.
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 MICJ25X60-30S FAQ
This 25 mm bore cylinder uses a 1/8" port and generates 245.3 N push / 206.1 N pull at 0.5 MPa, and 343.4 N push / 288.5 N pull at 0.7 MPa. Its theoretical maximum force is 50 kgf at 1.0 MPa.
An external screw shortens the extend stroke by up to 30 mm (usable extend 30-60 mm), while the needle-set air cushion decelerates the piston at both ends. The -S suffix means it has a magnet for CMSG/DMSG/EMSG sensors. The cushion only decelerates and does not lock the piston; it will drift on air loss.
