Airtac MICJ Adjustable Mini Cylinder MICJ25X120-30
The AirTAC Airtac MICJ Adjustable Mini Cylinder MICJ25X120-30 is a genuine double acting, adjustable stroke + cushion round-body mini air cylinder with a Ø25mm bore and 120mm 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 MICJ25X120-30
Trim the forward stop by up to 30 mm on site without swapping hardware: this MICJ25X120-30 mini cylinder pairs an external extend-stop screw with a needle-adjustable air cushion at both ends to dial in the exact 90-120 mm forward position and soak up high-speed shock. Built as a double-acting, stainless-steel round-body actuator, it drops directly into standard ISO 6432 mini-cylinder brackets and clevises.
The Ø25 bore delivers 245.3 N of push force at 0.5 MPa, yielding a safe working load of roughly 147 N or a 12.5 kg vertical lift with a 2:1 margin. It uses a 1/8" port, a Ø10 rod with an M10x1.25 male thread, and runs at 30-800 mm/s. Note this SKU lacks a magnet, so it cannot host CMSG/DMSG/EMSG sensors.

Where the Airtac MICJ Adjustable Mini Cylinder MICJ25X120-30 Is Used
Divert Gate Tuning
Dial the extend stop in 5 mm increments to shift a divert gate profile while the adjustable cushion absorbs the impact of fast 12 kg carton strikes.
Variable Stroke Sealing
Adjust the 120 mm extend down to 90 mm to press different box sizes, letting the needle cushion decelerate the 245 N push before contact.
Adjustable Forming Stop
Set precise forward material stops on the fly for changing part lengths, using the stainless body to resist mild washdown corrosion.
Is the Airtac MICJ Adjustable Mini Cylinder MICJ25X120-30 the Right Cylinder?
If 245.3 N at 0.5 MPa is too much, step down to the Ø20 bore (157.0 N push); if you need more muscle, move up to the Ø32 bore (402.2 N push). Choose this Ø25 adjustable-stroke model when you need to fine-tune the extend end on the fly and rely on the dual air cushions to decelerate heavy fast moves. The stop screw sets the end position but is not a mid-stroke lock.
For mounting, use LB foot, FA flange, or TC trunnion brackets (the SDB pivot-block is not offered on this adjustable variant). Because this specific SKU has no magnet (-S), it cannot accept position sensors. Remember that a standard cylinder drifts on air loss, so add an external rod lock or pilot check valve if the load must be held.
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 MICJ25X120-30 FAQ
This double-acting cylinder uses a 1/8" port and delivers 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. The theoretical maximum force is 50 kgf at 1.0 MPa.
An external screw shortens the extend stroke by up to 30 mm (usable range 90-120 mm), while the needle-adjustable air cushion at both ends decelerates the piston near stroke end. This SKU has no magnet, so it cannot take CMSG/DMSG/EMSG sensors; you need the -S variant for sensing.
