About the Airtac MIJ Adjustable Cylinder MIJ40X500-40S
Dial in a precise forward end position on-site with the AirTAC MIJ40X500-40S, a round-body stainless mini cylinder featuring a 40 mm extend-stroke adjustment window. An external stop screw lets you shorten the forward stroke from its 500 mm nominal maximum down to 460 mm, absorbing setup tolerances without changing the cylinder. The retract stroke remains full length. Built with a stainless-steel barrel and Ø16 mm piston rod, this double-acting actuator handles mild corrosion and washdown environments. It delivers robust force, pushing with 628.3 N and pulling with 527.8 N at 0.5 MPa.
The Ø40 bore operates outside the ISO 6432 mounting standard but shares the durable riveted construction of the series. It uses a 1/4" port and a male M12x1.25 rod thread. Because this SKU includes the -S magnet, it directly supports CMSG, DMSG, and EMSG sensors for position detection. 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).

Where the Airtac MIJ Adjustable Cylinder MIJ40X500-40S Is Used
Pallet Changeover Diverter
Quickly alter the extend stop by up to 40 mm to accommodate different pallet widths on a washdown-ready stainless line, keeping retract timing consistent.
Vertical Lift Gate
Raise light gates or doors using the 32 kg vertical lift capacity, relying on the external stop screw to set precise open positions across multiple machine setups.
Is the Airtac MIJ Adjustable Cylinder MIJ40X500-40S the Right Cylinder?
The 40 mm external stop screw is invaluable for changeover jobs, letting one part number cover several intermediate stops by trimming the extend end only. If your application requires holding a load vertically on air loss, note that this cylinder will drift; the stop screw sets the end position but is not a mid-stroke lock or brake. For secure load holding, integrate an external rod lock or pilot-operated check valve.
Mounting options include LB foot, FA flange, and TC trunnion brackets, but the SDB pivot-block is not available on this adjustable-stroke variant. Back cover choices cover CA, U, R, and CM styles. The integrated -S magnet allows you to bolt on CMSG, DMSG, or EMSG switches exactly where you need position feedback.
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 MIJ40X500-40S FAQ
This double-acting cylinder pushes with 628.3 N and pulls with 527.8 N at 0.5 MPa. At 0.7 MPa, push is 879.6 N and pull is 738.9 N. The theoretical maximum force is 128.1 kgf at 1.0 MPa. It features a 1/4" air port and a male M12x1.25 rod thread.
The external stop screw shortens the extend stroke by up to 40 mm on-site, allowing a usable forward range of 460-500 mm; the retract stroke remains full. The -S suffix indicates a built-in piston magnet, enabling CMSG, DMSG, or EMSG sensors for position detection.
