About the Airtac MICJ Adjustable Mini Cylinder MICJ40X80-10
Shave up to 10 mm off the forward end position right at the machine with the AirTAC MICJ40X80-10, a 40 mm bore round-body mini cylinder built from stainless steel for reliable mild-corrosion and washdown resistance. An external stop screw dials in the extend stroke from 70 to 80 mm, while a needle-adjustable air cushion at both ends absorbs high-speed impact. This combination lets you set the exact forward stop and control the end-of-stroke shock simultaneously.
As a double-acting actuator, it delivers substantial force, pushing with 628.3 N and pulling with 527.8 N at 0.5 MPa. It operates at speeds from 30 to 800 mm/s, uses a 1/4" port, and features a 16 mm rod with an M12x1.25 male thread. Note this is a non-ISO-6432 size, and because this specific SKU lacks the -S magnet option, it cannot accept CMSG, DMSG, or EMSG sensors.

Specifications follow the official AirTAC MI/MIC (ISO 6432) datasheet. Barrel & rod: stainless steel (round-body, riveted construction). Thread options: PT (blank) / G. Note: the Ø40 bore is a larger, non-ISO-6432 size.
Theoretical Output Force (Ø40mm)
| Pressure | Force (both ways) |
|---|---|
| 0.5 MPa | 528 N |
| 0.7 MPa | 739 N |
| Max (@1.0 MPa) | 108 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 MICJ40X80-10 Is Used
Pallet Deceleration Stop
Use the adjustable forward end position to halt heavy pallets on a line, letting the needle-set air cushion soak up the kinetic energy without slamming the 16 mm rod.
Vertical Lift Gate
Lift gates or materials up to 32 kg safely, using the 1/4" port double-acting power to raise the load and the adjustable stop to set the exact open height limit.
Is the Airtac MICJ Adjustable Mini Cylinder MICJ40X80-10 the Right Cylinder?
Choose the MICJ40X80-10 when you need heavy mini-cylinder force combined with a dialed-in extend stop and high-speed cushioning for precise, repetitive positioning.
Keep in mind that the adjustable stop screw and the air cushions only manage the end-of-stroke motion; they do not lock the piston or hold a load mid-stroke if air pressure drops. If your application requires the load to be held securely during air loss or valve centering, you must add an external rod lock or a pilot-operated check valve. For mounting, you can use LB foot, FA flange, or TC trunnion brackets, but the SDB pivot block is not available on this adjustable-stroke 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 MICJ40X80-10 FAQ
At 0.7 MPa, the push increases to 879.6 N and the pull to 738.9 N. The theoretical maximum force is 128.1 kgf at 1.0 MPa.
An external screw shortens the extend stroke by up to 10 mm on-site, while needle-adjustable air cushions at both ends decelerate the piston near the stroke ends to absorb high-speed shock. The cushions only decelerate; they do not lock or hold the load. If you need to hold a vertical load on air loss, use an external rod lock or pilot check valve. This SKU lacks a magnet, so it cannot take sensors unless you switch to the -S variant.
