About the Airtac MICJ Adjustable Mini Cylinder MICJ40X350-10
Dial in a precise forward stop on-site with the AirTAC MICJ40X350-10, a stainless-steel round-body mini cylinder featuring a 10 mm adjustable extend stroke. An external screw trims the forward end position down to 340 mm without swapping cylinders, while a needle-set adjustable air cushion at both ends soaks up high-speed shock. This double-acting actuator uses a 1/4" port and a Ø16 mm rod with an M12x1.25 male thread.
Note this SKU lacks a magnet and cannot accept CMSG, DMSG, or EMSG sensors; the -S variant is required for position sensing.

| Bore size | Ø40 mm |
| Stroke | 350 mm |
| Acting type | Double acting, double rod, adjustable stroke + cushion |
| 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 MICJ40X350-10 Is Used
Case Flap Folding
Folds heavy cardboard flaps on large cartons, adjusting the forward position by up to 10 mm to accommodate varying box sizes without changing tooling.
Pallet Stop Gate
Acts as a robust stop gate for heavy pallets, using the dual adjustable air cushions to decelerate the 40 mm bore piston smoothly when arresting forward momentum.
Is the Airtac MICJ Adjustable Mini Cylinder MICJ40X350-10 the Right Cylinder?
Use this model when you need fast, settable-position moves where the 10 mm extend adjuster and dual air cushions prevent harsh impacts at the 30-800 mm/s operating speed range. The external stop screw sets the end position but is not a mid-stroke lock.
Because a standard cylinder does not hold its load on air loss, the piston will drift if pressure drops; for vertical or suspended loads, install an external rod lock or pilot-operated check valve. Mount this actuator using LB foot, FA flange, or TC trunnion brackets (SDB pivot-block is not available on this adjustable variant). The cushion needle only decelerates the piston near the stroke end and does not function as a brake.
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 MICJ40X350-10 FAQ
At 0.7 MPa, push increases to 879.6 N and pull to 738.9 N. The theoretical maximum force is 128.1 kgf at 1.0 MPa. It features a 1/4" air port.
An external screw shortens the extend stroke by up to 10 mm on-site, allowing precise end-position tuning without replacing the cylinder. The adjustable air cushion at both ends uses a needle valve to absorb high-speed shock near the end of travel. This SKU has no magnet and cannot take sensors; the -S variant is required for CMSG, DMSG, or EMSG switches.
