Airtac MICJ Adjustable Mini Cylinder MICJ25X80-100
The AirTAC Airtac MICJ Adjustable Mini Cylinder MICJ25X80-100 is a genuine double acting, adjustable stroke + cushion round-body mini air cylinder with a Ø25mm bore and 80mm 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 MICJ25X80-100
Trim the forward stop on site without swapping hardware: the AirTAC MICJ25X80-100 uses an external screw to shorten the extend end by up to 100 mm, giving a usable 0-80 mm forward stroke while retract remains full. A needle-set variable air cushion at both ends soaks up high-speed shock so you control both the end position and the impact deceleration.
Built as a stainless-steel round-body riveted mini cylinder (not a tie-rod or profile type), the Ø25 bore uses the ISO 6432 mounting interface and a 1/8" port. It delivers 245.3 N of push force at 0.5 MPa, translating to a safe working load of about 147 N or a 12.5 kg vertical lift with a 2:1 margin. Note this SKU lacks the -S magnet, so it cannot accept CMSG/DMSG/EMSG sensors.

Where the Airtac MICJ Adjustable Mini Cylinder MICJ25X80-100 Is Used
Adjustable Press Tending
Dial in a 0-80 mm extend stroke to press lightweight fittings, using the 245 N push force and dual air cushions to prevent end-of-stroke shock on rapid cycles.
Dynamic Divert Gate
Trim the extend position on the fly to deflect packages of varying sizes without changing cylinders, relying on the adjustable cushion to absorb high-speed impacts.
Carton Flap Folding
Set a precise forward stop for folding carton flaps, using the 12.5 kg vertical lift capacity to manage the mechanism while the needle valve softens the stop.
Is the Airtac MICJ Adjustable Mini Cylinder MICJ25X80-100 the Right Cylinder?
Size both ways against the 245.3 N push force at 0.5 MPa: if your load is lighter, the Ø20 bore provides 157 N, while heavier setups step up to the Ø32 bore at 402 N. The adjustable stop plus dual air cushions shine in fast set-position moves where you need to dial in a precise forward end without mechanical hard stops clanging.
The stop screw sets the extend end position only—it is not a mid-stroke lock, and the cushion only decelerates near the stroke end. If the application must hold a load on air loss, add an external rod lock or pilot check valve. Mount via LB foot, FA flange, or TC trunnion (SDB pivot-block is not offered on this adjustable variant).
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 MICJ25X80-100 FAQ
This Ø25 bore cylinder features a 1/8" port and an M10x1.25 male rod thread. At 0.5 MPa it provides 245.3 N push and 206.1 N pull; at 0.7 MPa it provides 343.4 N push and 288.5 N pull. The theoretical maximum force is 50 kgf at 1.0 MPa.
An external screw shortens the extend end by up to 100 mm (usable 0-80 mm), while the needle-set air cushion at both ends decelerates the piston near stroke ends to absorb shock. This SKU has no magnet (-S), so it cannot take CMSG/DMSG/EMSG sensors; the stainless steel build resists mild corrosion.
