About the Airtac MIJ Adjustable Cylinder MIJ40X500-30S
Dial in a precise forward end position on-site with the AirTAC MIJ40X500-30S, a round-body stainless steel mini cylinder featuring a 30 mm extend-stroke adjustment window. An external stop screw lets you shorten the forward stroke from its 500 mm nominal length down to 470 mm, absorbing setup tolerances without swapping parts. Retract travel remains full length.
The riveted stainless barrel and Ø16 mm piston rod resist mild corrosion and washdown environments. This Ø40 bore size is a non-ISO-6432 format, yet it retains the compact mini footprint and uses a 1/4" port with an M12x1.25 male rod thread. The built-in magnet (-S) supports CMSG, DMSG, and EMSG position switches. Fixed TPU bumper pads decelerate the stroke ends across the 30-800 mm/s speed range.

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).

Is the Airtac MIJ Adjustable Cylinder MIJ40X500-30S the Right Cylinder?
When sizing this actuator, compare it against adjacent bores. The 30 mm external stop screw is ideal for changeover jobs or taking up mechanical tolerances, letting one part number cover several forward stops. Remember that the stop screw sets the end position but is not a mid-stroke lock. The piston will drift on air loss, so fit an external rod lock or pilot check valve if you must hold a suspended load. Mounting options include LB foot, FA flange, and TC trunnion (the SDB pivot block is not available on this adjustable variant). Because this SKU includes the -S magnet, you can directly mount CMSG, DMSG, or EMSG sensors.
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 MIJ40X500-30S FAQ
The theoretical maximum force is 128.1 kgf at 1.0 MPa.
An external stop screw shortens the extend stroke by up to 30 mm (usable forward travel 470-500 mm) while retract remains full; the screw is an end-position stop, not a mid-stroke lock. The -S suffix means a piston magnet is built-in for CMSG, DMSG, or EMSG sensors.
