Airtac MICJ Adjustable Mini Cylinder MICJ25X250-10S
The AirTAC Airtac MICJ Adjustable Mini Cylinder MICJ25X250-10S is a genuine double acting, adjustable stroke + cushion round-body mini air cylinder with a Ø25mm bore and 250mm 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 MICJ25X250-10S
Dial in the forward stop on site without swapping hardware: this stainless round-body mini cylinder shortens the extend end by up to 10 mm via an external screw, yielding a usable forward travel of 240-250 mm. An adjustable air cushion at both ends soaks up high-speed shock, letting you set the position and control the impact simultaneously.
Built with a stainless barrel and rod for mild washdown resistance, the Ø25 bore conforms to the ISO 6432 mounting interface for standard mini brackets. 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. The -S suffix means a piston magnet is installed for CMSG, DMSG or EMSG sensors.

Where the Airtac MICJ Adjustable Mini Cylinder MICJ25X250-10S Is Used
Divert Gate Actuation
Trims the 250 mm extend by 10 mm to hit a divert gate perfectly, while the dual air cushions absorb shock from 800 mm/s conveyor speeds.
Carton Flap Folding
Uses the 245 N push force to fold heavy cardboard flaps, relying on the adjustable stop to prevent crushing the carton edge.
Vertical Parts Lift
Lifts 12.5 kg packages vertically with a 2:1 safety margin, using the magnet for DMSG sensors to confirm the raised position.
Is the Airtac MICJ Adjustable Mini Cylinder MICJ25X250-10S the Right Cylinder?
At 0.5 MPa this bore pushes 245.3 N and pulls 206.1 N. If you need less force, the Ø20 drops to 157 N; if you need more, the Ø32 steps up to 402 N. Choose this model when you need precise extend positioning combined with high-speed shock absorption. The external screw sets the end position but is not a mid-stroke lock; the piston drifts on air loss, so add an external rod lock or pilot check valve to hold a load.
Mount using LB foot, FA flange or TC trunnion brackets (the SDB pivot block is not offered on this adjustable variant). Air ports are 1/8". Because this SKU includes the -S magnet, you can mount CMSG, DMSG or EMSG switches directly for position sensing.
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 MICJ25X250-10S FAQ
At 0.5 MPa it pushes 245.3 N and pulls 206.1 N. At 0.7 MPa it pushes 343.4 N and pulls 288.5 N. The theoretical maximum force is 50 kgf at 1.0 MPa. The air port size is 1/8".
An external screw shortens the extend stroke by up to 10 mm (retract remains full). Needle-set air cushions at both ends decelerate the piston near stroke ends but do not act as a lock. The cylinder does not hold position on air loss; use an external rod lock for that. The -S suffix enables CMSG, DMSG and EMSG sensors.
