About the Airtac MICJ Adjustable Mini Cylinder MICJ25X300-20
Trim the forward stop by up to 20 mm on site without swapping hardware using this adjustable-stroke mini cylinder. The MICJ25X300-20 delivers a robust 245.3 N push force at 0.5 MPa while its needle-set air cushions soak up high-speed shock at both ends. Built as a stainless-steel round-body unit, it resists mild corrosion and washdown environments.
It conforms to the ISO 6432 mounting interface for standard mini brackets and features a 1/8" port with an M10x1.25 male rod thread. Because this SKU lacks the -S magnet, it cannot host CMSG, DMSG or EMSG sensors. For vertical moves, expect a safe working lift of roughly 12.5 kg with a 2:1 margin.

Where the Airtac MICJ Adjustable Mini Cylinder MICJ25X300-20 Is Used
Long-Reach Diverting
Pushes packages across a wide belt at the end of a 300 mm extend, using the 20 mm stop screw to fine-tune the contact position without moving the bracket.
High-Speed Carton Sealing
Cycles rapidly to fold carton flaps, relying on the dual adjustable air cushions to prevent end-of-stroke impact while applying 245.3 N of push force.
Vertical Lift Gates
Lifts light access gates weighing up to 12.5 kg, using the full 300 mm stroke and the ISO 6432 mounting interface for easy clevis integration.
Is the Airtac MICJ Adjustable Mini Cylinder MICJ25X300-20 the Right Cylinder?
At 0.5 MPa this 25 mm bore generates 245.3 N push and 206.1 N pull. If you need less force, the 20 mm bore offers 157.0 N push; if you need more, step up to the 32 mm bore for 402.2 N push. The 20 mm external stop screw is ideal for fast set-position moves, letting you dial in the 280-300 mm extend window precisely.
Remember the stop screw and air cushions only decelerate near stroke end; they do not lock the piston mid-stroke or hold a load on air loss. For suspended loads, install an external rod lock or pilot check valve. Mount via LB, FA or TC brackets (SDB is unavailable here), and select the -S variant if you require 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 MICJ25X300-20 FAQ
This 25 mm 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 stop screw shortens the extend stroke by up to 20 mm (usable extend 280-300 mm), while needle valves adjust the air cushions at both ends to absorb high-speed shock. The cushions only decelerate near the stroke end; they do not lock the piston. This SKU has no -S magnet, so it cannot accept sensors.
