Airtac MICJ Adjustable Mini Cylinder MICJ20X25-10S
The AirTAC Airtac MICJ Adjustable Mini Cylinder MICJ20X25-10S is a genuine double acting, adjustable stroke + cushion round-body mini air cylinder with a Ø20mm bore and 25mm 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 MICJ20X25-10S
Trim the forward stop by up to 10 mm on-site without swapping hardware using this AirTAC MICJ20X25-10S mini cylinder. The external screw adjusts the extend end position only (yielding a 15-25 mm usable forward stroke), while a needle-set variable air cushion at both ends soaks up high-speed shock. The built-in piston magnet (-S) directly supports CMSG, DMSG, and EMSG reed or electronic switches for precise position detection.
Built as a stainless-steel, riveted round-body unit, the Ø20 mm bore and M8x1.25 male rod thread resist mild corrosion and washdown environments. Operating at 30-800 mm/s on a 1/8" air port, it delivers 157 N of push force at 0.5 MPa. This translates to a safe working load of roughly 94 N, capable of vertically lifting about 8 kg with a 2:1 safety margin. It conforms to the ISO 6432 mounting interface for standard mini brackets.

Where the Airtac MICJ Adjustable Mini Cylinder MICJ20X25-10S Is Used
Adjustable Sorting Diverter
Dial in the 15-25 mm extend stroke to deflect small packages on a conveyor, relying on the 157 N push force and dual air cushions to absorb the high-speed impact.
Light Press Assembly
Apply a precise 8 kg pressing force to seat small components, tweaking the 10 mm extend stop on-site to accommodate varying material thicknesses.
Lab Fluid Dispense
Use the -S magnet with DMSG sensors to trigger a dispense valve at the exact adjusted extend position, benefiting from the stainless build in wipe-down settings.
Is the Airtac MICJ Adjustable Mini Cylinder MICJ20X25-10S the Right Cylinder?
When sizing this 20 mm bore, step down to the 16 mm variant (100.5 N push @0.5 MPa) for lighter loads, or step up to the 25 mm bore (245.3 N push @0.5 MPa) if you need more thrust. The adjustable stop and dual air cushions shine in fast set-position moves where you must dial in the forward end and control impact without external shock absorbers. Mount via LB foot, FA flange, or TC trunnion (SDB pivot-block is not available on this adjustable variant). Remember that the stop screw sets the end position but is not a mid-stroke lock; the cylinder drifts on air loss, so add an external rod lock or pilot check valve for held loads.
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 MICJ20X25-10S FAQ
This 20 mm bore cylinder features a 1/8" air port and generates 157 N push / 131.9 N pull at 0.5 MPa, and 219.8 N push / 184.7 N pull at 0.7 MPa. The theoretical maximum force is 32 kgf at 1.0 MPa.
The external screw shortens the extend stroke by up to 10 mm (retract remains full), while the needle-set variable air cushion at both ends decelerates the piston near stroke end to absorb shock. The -S indicates a built-in piston magnet for CMSG, DMSG, or EMSG sensors.
