About the Airtac MIJ Adjustable Cylinder MIJ40X500-100S
Trimming the forward end by up to 100 mm via an external stop screw, this double-acting round-body mini cylinder lets you dial in the exact extend position from 400 to 500 mm without changing the unit. The retract stroke remains full. It features a stainless-steel barrel and piston rod to resist mild corrosion and washdown environments.
This -S variant includes a piston magnet for CMSG, DMSG, or EMSG sensors, and relies on fixed TPU bumper pads to decelerate the stroke end.
Airtac MIJ Adjustable Cylinder MIJ40X500-100S Technical Specifications
| Model | Airtac MIJ Adjustable Cylinder MIJ40X500-100S |
|---|---|
| Series | MIJ mini cylinder |
| Bore size | Ø40 mm |
| 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 |
| Cushion | Fixed TPU bumper pads |
| Max standard stroke | Up to 500 mm |
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 MIJ40X500-100S Is Used
Pallet Diverter Gate
Shifts heavy diverter gates on packaging lines, using the 100 mm extend trim to fine-tune the gate angle for varying box widths without swapping hardware.
Clamp Positioning
Extends to clamp large machined castings, using the on-site screw to shorten the forward stroke and compensate for raw part tolerances.
Is the Airtac MIJ Adjustable Cylinder MIJ40X500-100S the Right Cylinder?
When sizing this 40 mm bore, dropping down to a 32 mm MIJ reduces the 0.5 MPa push force to 402.2 N, while no larger standard MIJ bore exists. The 100 mm adjustment window is ideal for taking up mechanical tolerances or staging feeds during changeovers, letting one part number cover several stops. Note that the stop screw sets the end position but is not a mid-stroke lock; the piston will drift on air loss, so use an external rod lock or pilot check valve for holding loads. Mounting options include LB, FA, and TC styles, but SDB is not available on this adjustable variant.
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 MIJ40X500-100S FAQ
The theoretical maximum force is 128.1 kgf at 1.0 MPa.
An external stop screw shortens the extend stroke by up to 100 mm on-site, while retract stays full. The -S suffix means a built-in piston magnet is present for CMSG, DMSG, or EMSG sensors. The stainless build resists mild corrosion.
