About the Airtac MICJ Adjustable Mini Cylinder MICJ40X160-30
Dial in your forward stop on-site with the AirTAC MICJ40X160-30, a double-acting round-body mini cylinder featuring a 30 mm adjustable extend stroke. An external screw trims the extend end position down to 130 mm without swapping hardware, while a needle-set variable air cushion at both ends soaks up high-speed shock.
This non-ISO-6432 Ø40 unit delivers serious muscle, pushing 879.6 N at 0.7 MPa and handling a theoretical maximum of 128.1 kgf at 1.0 MPa. Note this SKU lacks the -S magnet, so it cannot host 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 MICJ40X160-30 Is Used
Heavy Carton Diverter
Pushes weighted packaging carts off a high-speed line using the 879.6 N extend force, relying on the tuned air cushion to prevent end-of-stroke slamming.
Adjustable Press Stop
Sets a precise 145 mm forward forming position on the fly via the 30 mm stop screw, avoiding the need to physically swap cylinders for different part heights.
Is the Airtac MICJ Adjustable Mini Cylinder MICJ40X160-30 the Right Cylinder?
There is no larger standard MICJ bore available, making this the top choice for heavy mini-cylinder tasks. The 30 mm extend adjuster paired with the dual air cushions is ideal for fast, repetitive set-position moves where you must tune the forward impact. Mount via LB foot, FA flange, or TC trunnion (the SDB pivot-block is not offered on this adjustable variant). Remember the stop screw sets the end position but is not a mid-stroke lock; the piston will drift on air loss, so add an external rod lock or pilot check valve for held loads.
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 MICJ40X160-30 FAQ
This Ø40 bore cylinder features a 1/4" air port and a Ø16 mm rod with an M12x1.25 male thread.
An external screw shortens the extend stroke by up to 30 mm (usable range 130-160 mm), while the needle-set variable air cushions at both ends decelerate the piston near stroke ends to absorb high-speed shock. This SKU has no -S magnet and cannot take sensors. The cylinder does not hold position on air loss; use an external rod lock or pilot check valve for load holding.
