About the Airtac MICJ Adjustable Mini Cylinder MICJ16X250-40S
Trim the forward stop by up to 40 mm on site without swapping cylinders using the AirTAC MICJ16X250-40S. This double-acting stainless steel round-body mini cylinder pairs that external extend adjuster with a variable air cushion at both ends, letting you set the position and soak up high-speed shock simultaneously. The built-in magnet (-S) supports CMSG, DMSG and EMSG sensors for precise switching.
The stainless barrel and rod resist mild corrosion and washdown environments, while the Ø16 mm body conforms to the ISO 6432 mounting interface for standard mini brackets.

Specifications follow the official AirTAC MI/MIC (ISO 6432) datasheet. Barrel & rod: stainless steel (round-body, riveted construction). Thread options: PT (blank) / G.
Theoretical Output Force (Ø16mm)
| Pressure | Force (both ways) |
|---|---|
| 0.5 MPa | 86 N |
| 0.7 MPa | 121 N |
| Max (@1.0 MPa) | 18 kgf |
MIJ / MICJ are double-rod: the rear rod that carries the stroke adjuster exits the rear cover, so both piston faces lose rod area. The rod-side (annular) area is used for both directions (conservative).

Where the Airtac MICJ Adjustable Mini Cylinder MICJ16X250-40S Is Used
High-Speed Diverting
Rely on the adjustable air cushion to absorb shock at the end of a fast 250 mm extend cycle, preventing impact damage when routing small packages.
Lab Washdown Station
Leverage the stainless steel barrel and rod for mild corrosion resistance in damp lab environments, adjusting the extend end on-site to fit various fixture sizes.
Is the Airtac MICJ Adjustable Mini Cylinder MICJ16X250-40S the Right Cylinder?
The 40 mm extend adjustment window is ideal for fast, settable-position moves where you need to dial in a precise forward stop without machining spacers.
Remember that the stop screw and air cushion only decelerate the piston near the stroke end; they do not function as a mid-stroke lock or brake. If the load must be held on air loss, install an external rod lock or pilot-operated check valve. For mounting, use LB, FA or TC attachments, as the SDB pivot block is not available 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 MICJ16X250-40S FAQ
This double-acting cylinder pushes at 100.5 N and pulls at 86.4 N at 0.5 MPa. At 0.7 MPa, push is 140.7 N and pull is 120.9 N, with a theoretical max of 20.5 kgf at 1.0 MPa. It uses an M5×0.8 air port and a 6 mm piston rod with an M6x1.0 male thread.
An external screw shortens the extend end position by up to 40 mm on site, giving a usable extend range of 210-250 mm, while retract remains full stroke. A needle-set variable air cushion at both ends decelerates the piston near the ends to absorb high-speed shock. The -S suffix means it has a built-in magnet for CMSG, DMSG or EMSG sensors.
