About the Airtac MICJ Adjustable Mini Cylinder MICJ16X250-20S
Dial in the forward stop on-site without swapping hardware: this stainless-steel round-body mini cylinder shortens the extend end by up to 20 mm via an external screw, giving a usable forward range of 230-250 mm. The MICJ16X250-20S pairs that adjustable extend stroke with a needle-set variable air cushion at both ends, soaking up high-speed shock to prevent end-cap impact damage.
Built to the ISO 6432 mini-cylinder mounting interface, the Ø16 bore drops into standard brackets and clevises. The -S suffix adds a piston magnet for CMSG/DMSG/EMSG switches, while the M5×0.8 port and M6x1.0 male rod thread keep pneumatic and mechanical integration simple.

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 MICJ16X250-20S Is Used
Light-Part Ejection
Pushes small molded components out of a fixture with 100.5 N at 0.5 MPa, using the 20 mm extend trim to hit the exact drop point without recalculating the full 250 mm stroke.
Package Diverting
Sorts light cartons on a belt line, relying on the adjustable air cushion to decelerate the rod smoothly at 800 mm/s before the end of travel.
Vertical Lift Stops
Raises small bins weighing up to 5.1 kg, using the external screw to fine-tune the extend endpoint so the bin aligns perfectly with the shelf.
Is the Airtac MICJ Adjustable Mini Cylinder MICJ16X250-20S the Right Cylinder?
For lighter moves, the MIJ bumper-only series lacks the air cushion, making this MICJ the better choice for high-speed 30-800 mm/s cycles; if you need more push, stepping up to the Ø20 bore raises the 0.5 MPa push force to 157 N. The external stop screw sets the extend end position but is not a mid-stroke lock—the piston will drift on air loss, so specify an external rod lock or pilot check valve for held loads. Mount via LB foot, FA flange, or TC trunnion (the SDB pivot-block is not offered on this adjustable variant), and use the built-in magnet 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 MICJ16X250-20S FAQ
This double-acting cylinder pushes with 100.5 N and pulls with 86.4 N at 0.5 MPa. At 0.7 MPa, push is 140.7 N and pull is 120.9 N. The theoretical max force is 20.5 kgf at 1.0 MPa, and the air port is M5×0.8.
An external screw shortens the extend stroke by up to 20 mm (retract remains full), while a needle valve adjusts the variable air cushion at both ends to absorb high-speed shock. The cushion only decelerates near the end of travel—it is not a brake. The -S suffix means it has a magnet for CMSG/DMSG/EMSG sensors, but it will drift on air loss; use an external rod lock to hold a load.
