Airtac MICJ Adjustable Mini Cylinder MICJ25X300-10S
The AirTAC Airtac MICJ Adjustable Mini Cylinder MICJ25X300-10S is a genuine double acting, adjustable stroke + cushion round-body mini air cylinder with a Ø25mm bore and 300mm 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 MICJ25X300-10S
Trimming the forward end by up to 10 mm on-site, the AirTAC MICJ25X300-10S lets you dial in a 290-300 mm extend position without swapping hardware. This double-acting, round-body stainless-steel mini cylinder pairs that external stop screw with an adjustable air cushion at both ends, soaking up high-speed shock as the piston reaches its set endpoint.
Built to the ISO 6432 mounting interface, the Ø25 body drops into standard mini brackets and uses a 1/8" port with an M10x1.25 male rod thread. The stainless barrel and rod resist mild washdown corrosion, while the integrated magnet (-S) supports CMSG, DMSG, or EMSG sensors. Delivering 245.3 N of push force at 0.5 MPa, it provides a safe working load of roughly 147 N, or about a 12.5 kg vertical lift with a 2:1 margin.

Where the Airtac MICJ Adjustable Mini Cylinder MICJ25X300-10S Is Used
Precision Cutoff Saw
Dial in the 290-300 mm extend stop to position a lumber stop block, relying on the 245.3 N push force and end cushions to absorb high-speed impact.
Divert Gate Actuation
Set the exact divert distance on a packaging line, using the adjustable forward end to tune the gate opening without changing the entire cylinder.
Vertical Parts Lift
Lift components up to 12.5 kg with a 2:1 safety margin, letting the dual air cushions decelerate the 300 mm stroke smoothly at the top end.
Is the Airtac MICJ Adjustable Mini Cylinder MICJ25X300-10S the Right Cylinder?
For lighter pushes, the Ø20 bore yields 157.0 N at 0.5 MPa, whereas stepping up to the Ø32 provides 402.2 N if this 245.3 N output is insufficient. The adjustable stop and dual cushions shine in fast set-position moves where you must precisely tune the 290-300 mm forward endpoint and decelerate smoothly.
Remember that the stop screw sets the end position but does not lock the piston mid-stroke; the cylinder drifts on air loss, so add an external rod lock or pilot check valve for suspended loads. Mount via LB, FA, or TC (SDB is unavailable here), and use the -S magnet to fit reed or electronic switches.
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 MICJ25X300-10S 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 max force is 50 kgf at 1.0 MPa, and the air port is 1/8".
An external screw shortens the extend stroke by up to 10 mm (retract remains full), while needle-set air cushions at both ends decelerate the piston near the endpoints. The -S magnet enables CMSG/DMSG/EMSG sensors, but the screw is not a mid-stroke lock, so the piston drifts on air loss.
