About the Airtac MICJ Adjustable Mini Cylinder MICJ40X175-20S
Dial in a precise forward stop on-site with the AirTAC MICJ40X175-20S, a round-body stainless steel mini cylinder built for heavy-duty pneumatic tasks. An external screw trims the extend end position by up to 20 mm, giving you a usable forward range of 155-175 mm without swapping hardware. Needle-set variable air cushions at both ends soak up high-speed shock to protect your tooling.
This double-acting actuator delivers substantial power, pushing with 628.3 N and pulling with 527.8 N at 0.5 MPa. The 1/4" port and M12x1.25 male rod thread accommodate higher airflow for robust force, while the -S suffix means a built-in magnet enables CMSG, DMSG, or EMSG sensor tracking.

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 MICJ40X175-20S Is Used
Heavy Carton Diversion
Pushes loaded pallets or heavy cartons at speed on a packaging line, using the 20 mm extend adjustment to fine-tune the contact position while the dual air cushions absorb the 628 N impact.
Stamping Pin Setting
Drives a marking or stamping head into metal parts, relying on the adjustable forward stop to dial in depth precisely without machine rework, handling the 32 kg load effortlessly.
Vertical Lift Gate
Actuates a weighted material handling gate vertically, using the needle cushions to prevent slamming at the top and bottom of the 175 mm travel, ensuring smooth product flow.
Is the Airtac MICJ Adjustable Mini Cylinder MICJ40X175-20S the Right Cylinder?
When sizing this 40 mm bore unit, dropping down to the MICJ32 drops your 0.5 MPa push force to 402.2 N, whereas no larger ISO standard round-body mini exists above it in this family.
Keep in mind the stop screw and air cushion only decelerate near the stroke end; they do not lock the piston mid-travel or hold a load on air loss. If gravity or drift is a concern, install an external rod lock or pilot check valve. Mount via LB foot, FA flange, or TC trunnion (SDB pivot-block is not available here), and rely on the -S magnet for your electronic or reed 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 MICJ40X175-20S FAQ
This 40 mm bore cylinder features a 1/4" air port and an M12x1.25 male rod thread. 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.
An external stop screw shortens the extend stroke by up to 20 mm on-site (usable range 155-175 mm), while the retract stroke remains fixed. Needle valves provide a variable air cushion at both ends to decelerate the piston at high speed. Note that this is not a mid-stroke lock; the -S magnet allows use of CMSG, DMSG, or EMSG sensors.
