About the Airtac MICJ Adjustable Mini Cylinder MICJ40X175-40S
Dial in a precise forward stop without swapping hardware: the MICJ40X175-40S uses an external screw to shorten the extend stroke by up to 40 mm on site, yielding a usable forward range of 135-175 mm. This round-body stainless steel mini cylinder pairs that settable end-position with a needle-adjustable air cushion at both ends, soaking up high-speed shock before impact.
The -S suffix equips the piston with a magnet for CMSG, DMSG or EMSG sensors, while the stainless barrel and rod shrug off mild washdown corrosion.

| Series | MICJ mini cylinder |
| Bore size | Ø40 mm |
| Stroke | 175 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 MICJ40X175-40S Is Used
Pallet Diverter Gate
Shifts heavy pallet flow at high speed, using the 40 mm extend trim to match the gate opening exactly while the dual air cushions absorb the 32 kg load impact.
Heavy Tote Pusher
Advances loaded totes off a roller lane, using the on-site stop screw to dial the push distance without re-engineering the machine frame.
Is the Airtac MICJ Adjustable Mini Cylinder MICJ40X175-40S the Right Cylinder?
At this 40 mm bore you are at the top of the MICJ range with no larger size available; if your move requires less force, stepping down to the 32 mm bore drops the 0.5 MPa push force to 402.2 N. Choose this 175 mm stroke model when you need a long reach combined with on-site adjustability to tune out mechanical deadbands. The external screw sets the extend end position only, and the dual cushions decelerate the load near stroke end. It will not hold a load on air loss, so fit an external rod lock or pilot check valve if drift is unacceptable. Mount via LB foot, FA flange or TC trunnion (the SDB pivot block is not offered on this adjustable variant).
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 MICJ40X175-40S FAQ
The theoretical maximum force is 128.1 kgf at 1.0 MPa.
An external screw shortens the extend stroke by up to 40 mm (retract remains full). A needle valve adjusts the air cushion at both ends to decelerate high-speed moves, but it is not a mid-stroke lock. The -S suffix means a piston magnet is built in for CMSG, DMSG or EMSG sensors.
