About the Airtac MIJ Adjustable Cylinder MIJ40X500-50S
Dialing in a precise forward end position on-site is effortless with this Ø40 mm round-body mini cylinder, thanks to an external stop screw that shortens the extend stroke by up to 50 mm without swapping parts. The AirTAC MIJ40X500-50S is a double-acting, stainless-steel riveted unit featuring a 500 mm stroke and a built-in piston magnet (-S) for position sensing.
The 1/4" port and M12x1.25 male rod thread accommodate high airflow and rigid mounting, while the stainless barrel and rod resist mild corrosion and washdown environments.

| Stroke | 500 mm |
| Acting type | Double acting, double rod, adjustable stroke |
| 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 MIJ Adjustable Cylinder MIJ40X500-50S Is Used
Carton Flap Folding
Extends 500 mm to fold large carton flaps, dialing back the forward stop by up to 50 mm to accommodate varying package heights without changing tooling.
Heavy Tray Stacking
Lifts loaded trays weighing up to 32 kg, using the adjustable end position to fine-tune the stacking height and absorb mechanical tolerances on the fly.
Is the Airtac MIJ Adjustable Cylinder MIJ40X500-50S the Right Cylinder?
The 50 mm adjustment window is ideal for absorbing mechanical tolerances or staging feeds during setup, letting one part number cover several intermediate stops. Remember the stop screw only trims the extend end (usable 450-500 mm) and is not a mid-stroke lock; the piston will drift on air loss, so fit an external rod lock or pilot check valve for held loads. Mount via LB foot, FA flange, or TC trunnion (SDB pivot-block is unavailable here), and use CMSG, DMSG, or EMSG sensors with the included -S magnet.
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 MIJ Adjustable Cylinder MIJ40X500-50S FAQ
The theoretical maximum force is 128.1 kgf at 1.0 MPa, and the air port size is 1/4".
An external stop screw shortens the extend stroke by up to 50 mm (usable extend 450-500 mm), but retract remains full and the screw is not a mid-stroke lock. The -S suffix denotes a built-in piston magnet for CMSG, DMSG, or EMSG sensors, and the stainless steel build resists mild corrosion.
