About the Airtac MICJ Adjustable Mini Cylinder MICJ40X350-40S
Dial in a precise forward stop on-site with the AirTAC MICJ40X350-40S, a round-body stainless steel mini cylinder built for double-acting operation. An external stop screw shortens the extend end position by up to 40 mm, giving a usable forward range of 310 to 350 mm, while a needle-set adjustable air cushion at both ends soaks up high-speed shock. The stainless barrel and rod resist mild corrosion and washdown environments.
It features a 1/4" port, an M12x1.25 male rod thread, and a built-in magnet (-S) for CMSG, DMSG or EMSG sensors. The cushion only decelerates near the stroke end, so fit an external rod lock if you need to hold a load on air loss.

| 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 MICJ40X350-40S Is Used
High-Speed Diverting
Use the 40 mm extend trim to set the exact gate position on a packaging line, relying on the dual air cushions to absorb shock during 800 mm/s actuation.
Vertical Lift Stops
Lift loads up to 32 kg safely, using the adjustable forward stop to hit a specific tier height without recalculating cylinder length for every station.
Washdown Sorting
Deploy the stainless construction in mildly corrosive food environments, dialing the extend end in by up to 40 mm to push varying box sizes onto exit chutes.
Is the Airtac MICJ Adjustable Mini Cylinder MICJ40X350-40S the Right Cylinder?
When sizing this 40 mm bore, moving down to the Ø32 MICJ drops the 0.5 MPa push force to 402.2 N, while no larger round-body mini exists in this family. Choose this model when you need to set a precise extend position without swapping cylinders, and control impact at speeds up to 800 mm/s. The stop screw sets the end position but is not a mid-stroke lock. Mount via LB foot, FA flange or TC trunnion, as the SDB pivot-block is not available on this adjustable variant. The included -S magnet enables 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 MICJ40X350-40S FAQ
This double-acting cylinder pushes 628.3 N and pulls 527.8 N at 0.5 MPa, and pushes 879.6 N and pulls 738.9 N at 0.7 MPa. The theoretical max force is 128.1 kgf at 1.0 MPa. It uses a 1/4" port and an M12x1.25 male rod thread.
An external screw shortens the extend stroke by up to 40 mm, letting you set the forward end position on-site. Needle-set air cushions at both ends decelerate the piston near stroke ends. It does not hold position on air loss, so use a pilot check valve for that. The -S magnet allows CMSG, DMSG and EMSG sensors.
