Airtac MICJ Adjustable Mini Cylinder MICJ25X60-40
The AirTAC Airtac MICJ Adjustable Mini Cylinder MICJ25X60-40 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 MICJ25X60-40
Trim the forward stop by up to 40 mm on site with the AirTAC MICJ25X60-40, a double-acting round-body stainless mini cylinder. A needle-set adjustable air cushion at both ends soaks up high-speed shock, letting you dial in the exact extend position from 20 to 60 mm while controlling impact. The 1/8" port and M10x1.25 male rod thread feed a Ø25 mm bore that delivers 245.3 N of push force at 0.5 MPa.
Built with a stainless-steel barrel and piston rod for mild corrosion and washdown resistance, this riveted construction uses the ISO 6432 mini-cylinder mounting interface for standard brackets. It yields a safe working load of about 147 N, meaning it can vertically lift around 12.5 kg with a 2:1 safety margin. Note this SKU lacks a magnet and cannot take a sensor; the -S variant is required for CMSG, DMSG, or EMSG switches.

Where the Airtac MICJ Adjustable Mini Cylinder MICJ25X60-40 Is Used
Adjustable Press Fit
Dial in a precise 20 to 60 mm extend for pressing small bearings, using the 245.3 N push force and needle cushion to prevent end-of-stroke impact.
Dynamic Divert Stop
Act as a retractable flight divertor that safely decelerates high-speed actuation while halting light packages on a washdown-ready stainless line.
Vertical Lift Gate
Raise and lower a 12.5 kg access flap using the 2:1 safety margin, relying on the external screw to fine-tune the open position.
Is the Airtac MICJ Adjustable Mini Cylinder MICJ25X60-40 the Right Cylinder?
When sizing, step down to the Ø20 bore for 157 N push at 0.5 MPa if your load is lighter, or move up to the Ø32 bore for 402.2 N if you need more thrust. The 40 mm extend adjuster and dual air cushions shine in fast set-position moves where you must tune the forward stop without swapping cylinders. For mounting, use LB foot, FA flange, or TC trunnion brackets, plus CA, U, R, or CM back covers; the SDB pivot-block is not available on this adjustable-stroke build.
Remember that the stop screw sets the end position but is not a mid-stroke lock. A plain cylinder does not hold its load on air loss—the piston drifts, and the cushion only decelerates near the stroke end. To hold a suspended load, add 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 MICJ25X60-40 FAQ
This Ø25 mm bore cylinder features a 1/8" port and an M10x1.25 male rod thread. It generates 245.3 N push and 206.1 N pull at 0.5 MPa, 343.4 N push and 288.5 N pull at 0.7 MPa, with a theoretical maximum of 50 kgf at 1.0 MPa.
An external screw shortens the extend stroke by up to 40 mm (usable range 20-60 mm), while the needle-set air cushion at both ends absorbs high-speed shock. This specific SKU has no magnet and cannot accept a sensor; you must use the -S variant for CMSG, DMSG, or EMSG switches.
