About the Airtac MICJ Adjustable Mini Cylinder MICJ40X150-50S
Dial in the exact forward stop on-site with the AirTAC MICJ40X150-50S, a stainless round-body mini cylinder featuring a 50 mm extend-stroke adjuster and dual adjustable air cushions. The external stop screw lets you trim the usable extend from 150 mm down to 100 mm without swapping hardware, while the needle valves soak up high-speed shock at both ends.
The built-in magnet (-S) supports CMSG, DMSG and EMSG position switches.
Airtac MICJ Adjustable Mini Cylinder MICJ40X150-50S Technical Specifications
| Model | Airtac MICJ Adjustable Mini Cylinder MICJ40X150-50S |
|---|---|
| Series | MICJ mini cylinder |
| Bore size | Ø40 mm |
| Stroke | 150 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 |
| Cushion | Variable air cushion, both ends |
| Max standard stroke | Up to 500 mm |
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 MICJ40X150-50S Is Used
Heavy Carton Diverting
Pushes heavy cartons at high speed on a packaging line, using the 50 mm extend trim to dial in the exact diverting distance while the air cushion prevents end-of-stroke slamming.
Vertical Material Lowering
Lowers 30 kg fixtures safely; the dual cushions decelerate the load smoothly at the bottom, and the stop screw fine-tunes the drop height without re-mounting.
Is the Airtac MICJ Adjustable Mini Cylinder MICJ40X150-50S the Right Cylinder?
Because 40 mm is the largest standard round-body mini size here, moving up requires a different frame. Choose this model when you need high thrust combined with on-the-fly extend tuning and shock absorption at speeds up to 800 mm/s.
The adjustable stop screw sets the forward 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 holding suspended loads. Mount via LB foot, FA flange or TC trunnion (SDB pivot-block is unavailable on this adjustable variant). Position sensing requires the included -S magnet for switch readiness.
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 MICJ40X150-50S FAQ
This 40 mm bore cylinder uses a 1/4" port. The theoretical maximum force is 128.1 kgf at 1.0 MPa.
An external screw shortens the extend stroke by up to 50 mm (usable range 100-150 mm); retract remains full. Needle valves adjust the air cushion at both ends to decelerate high-speed moves, but this is not a mid-stroke lock. The -S magnet enables CMSG/DMSG/EMSG sensors, and the stainless build resists mild corrosion.
