About the Airtac MICJ Adjustable Mini Cylinder MICJ40X450-100S
Dial in your forward stop on-site without swapping cylinders: the MICJ40X450-100S uses an external screw to shorten the extend stroke by up to 100 mm, giving a usable forward range of 350-450 mm. As a double-acting round-body stainless mini cylinder, it pairs this settable position with a needle-adjustable air cushion at both ends to soak up high-speed shock. The stainless barrel and rod resist mild corrosion and washdown environments.
This Ø40 mm bore delivers substantial force, pushing with 628.3 N and pulling with 527.8 N at 0.5 MPa. It features a 1/4" port, an M12x1.25 male rod thread, and a built-in magnet (-S) for CMSG, DMSG or EMSG sensors. Operating pressure spans 0.15-1.0 MPa, with speeds of 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 MICJ40X450-100S Is Used
Heavy Carton Diversion
Pushes heavy cartons at 628 N on a packing line, using the 100 mm extend adjustment to tune the stop position for varying box sizes without changing mounts.
Vertical Press Dampening
Lowers a 30 kg tooling head rapidly, relying on the adjustable air cushion to absorb end-of-stroke shock while the stop screw sets the exact pressing depth.
Pallet Stop Gate
Acts as a robust pallet stop gate in washdown zones, where the stainless build resists moisture and the 1/4" port handles the air volume for swift 450 mm strokes.
Is the Airtac MICJ Adjustable Mini Cylinder MICJ40X450-100S the Right Cylinder?
The adjustable stop screw and dual air cushions are ideal for fast, repetitive set-position moves where you must tune the forward impact. The screw sets the end position but is not a mid-stroke lock. A plain cylinder drifts on air loss, so fit an external rod lock or pilot check valve to hold a suspended load. Mount via LB foot, FA flange or TC trunnion (SDB pivot-block is not available). The -S magnet enables CMSG, DMSG and EMSG switches.
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 MICJ40X450-100S FAQ
This Ø40 mm double-acting cylinder uses a 1/4" port. At 0.5 MPa it pushes with 628.3 N and pulls with 527.8 N. At 0.7 MPa it pushes with 879.6 N and pulls with 738.9 N. The theoretical maximum force is 128.1 kgf at 1.0 MPa.
An external screw shortens the extend stroke by up to 100 mm (usable forward range 350-450 mm); retract remains full. Needle valves adjust the air cushion at both ends to decelerate the piston near stroke ends. The cushion only decelerates and the stop screw sets the end position, neither acts as a mid-stroke lock. The -S magnet allows CMSG, DMSG and EMSG sensors for position detection.
