About the Airtac MICJ Adjustable Mini Cylinder MICJ40X75-50S
Shave up to 50 mm off the forward end position on-site with the AirTAC MICJ40X75-50S, a round-body stainless mini cylinder built for double-acting service. An external stop screw dials in the extend stroke from 25 to 75 mm, while a needle-set variable air cushion at both ends soaks up high-speed shock. The stainless barrel and rod shrug off mild washdown corrosion.
The -S suffix means a built-in piston magnet is present, ready for CMSG, DMSG, or EMSG switches. Air connects via a 1/4" port, and the M12x1.25 male rod thread handles the load.

| Stroke | 75 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 MICJ40X75-50S Is Used
High-Speed Diversion
Use the needle-set air cushion to decelerate the 16 mm rod smoothly when kicking heavy boxes at 800 mm/s, preventing end-cap shock.
Vertical Lifting Stops
Lift approximately 32 kg of inventory and fine-tune the extend position by up to 50 mm to match varying shelf heights without changing hardware.
Is the Airtac MICJ Adjustable Mini Cylinder MICJ40X75-50S the Right Cylinder?
Choose this adjustable-stroke variant when you need to fine-tune the forward stop without swapping cylinders, and use the dual air cushions to decelerate heavy 32 kg loads moving at 30-800 mm/s. Mount via LB foot, FA flange, or TC trunnion (the SDB pivot-block is not offered on this adjustable variant). The stop screw sets the end position but is not a mid-stroke lock; to hold a load on air loss, add an external rod lock or pilot check valve.
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 MICJ40X75-50S FAQ
This 40 mm bore cylinder pushes 628.3 N and pulls 527.8 N at 0.5 MPa. At 0.7 MPa it pushes 879.6 N and pulls 738.9 N, with a theoretical max of 128.1 kgf at 1.0 MPa. The air port is 1/4".
An external screw shortens the extend stroke by up to 50 mm on-site, and a needle valve adjusts the air cushion at both ends to absorb high-speed shock. The -S magnet enables CMSG/DMSG/EMSG sensors. The cushion only decelerates near stroke end; it is not a lock, so the piston drifts on air loss unless you add an external rod lock.
