About the Airtac MICJ Adjustable Mini Cylinder MICJ40X350-75
Trim the forward stop by up to 75 mm on site without swapping hardware using this AirTAC adjustable-extend round-body mini cylinder. It is a double-acting stainless steel unit featuring a needle-set variable air cushion at both ends to soak up high-speed shock, running at 30-800 mm/s. The Ø40 bore uses a 1/4" port and a 16 mm rod with an M12x1.25 male thread.
Because this SKU lacks the -S magnet, it cannot accept CMSG, DMSG, or EMSG sensors. Note that Ø40 is a non-ISO-6432 size, and the stop screw merely sets the end position rather than locking mid-stroke.

| Port size | 1/4" |
| Rod thread | M12×1.25 |
| Fluid | Air (filtered by 40µm element) |
|---|---|
| Operating pressure | 0.15 – 1.0 MPa |
| Proof pressure | 1.5 MPa |
| Temperature | -20 to +70 °C |
| Speed range | 30 – 800 mm/s |

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 MICJ40X350-75 Is Used
Heavy Clamping Press
Dial in the exact 275-350 mm clamp reach on heavy steel fixtures while the dual air cushions absorb the 879.6 N high-speed impact at 0.7 MPa.
Pallet Deceleration
Arrest fast-moving pallets weighing up to 32 kg safely; the adjustable extend stop sets the contact point and the needle cushion prevents end-of-stroke shock.
Is the Airtac MICJ Adjustable Mini Cylinder MICJ40X350-75 the Right Cylinder?
The 75 mm extend adjuster paired with the dual air cushions is ideal for fast set-position moves requiring precise impact control. Choose LB foot, FA flange, or TC trunnion mounts, as the SDB pivot-block is not offered on this adjustable variant.
Remember that a plain cylinder drifts on air loss, and the cushion only decelerates near the stroke end without acting as a brake. To hold a suspended load securely, integrate an external rod lock or a pilot-operated check valve into your circuit.
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 MICJ40X350-75 FAQ
This double-acting cylinder pushes 628.3 N and pulls 527.8 N at 0.5 MPa. At 0.7 MPa, push is 879.6 N and pull is 738.9 N. The theoretical maximum force is 128.1 kgf at 1.0 MPa. It features a 1/4" air port and a 16 mm piston rod.
An external screw shortens the extend stroke by up to 75 mm, giving a usable 275-350 mm forward travel, while a needle-set variable air cushion at both ends decelerates the piston near stroke ends. This SKU has no -S magnet, so it cannot take sensors. The cushion only decelerates and does not lock; use an external rod lock to hold a load on air loss.
