About the Airtac MIJ Adjustable Cylinder MIJ40X40-40
Trimming the forward end by up to 40 mm via an external stop screw, this round-body mini cylinder lets you dial in the exact forward position on-site without swapping parts.
As a double-acting actuator, it uses fixed TPU bumper pads to decelerate the stroke end and operates at speeds of 30-800 mm/s. It features a 1/4" air port and an M12x1.25 male rod thread. Without the -S suffix, this specific SKU lacks a magnet and cannot host CMSG, DMSG, or EMSG sensors.

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 MIJ40X40-40 Is Used
Heavy Diverter Gate
Set the exact extend stop to deflect heavy cartons on a conveyor, using the 40 mm trim to compensate for belt wear without changing the cylinder.
Washdown Stopper
Act as an end-of-line physical stop for products in a damp environment, relying on the stainless construction and fixed TPU bumper to absorb impacts.
Is the Airtac MIJ Adjustable Cylinder MIJ40X40-40 the Right Cylinder?
The 40 mm adjustment window is ideal for taking up mechanical tolerances during setup or covering multiple stop positions with one part number. Mounting options include LB foot, FA flange, and TC trunnion (the SDB pivot block is not available on this adjustable variant). Remember that the stop screw sets the extend end position only and is not a mid-stroke lock.
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 MIJ40X40-40 FAQ
The theoretical maximum force is 128.1 kgf at 1.0 MPa. This bore uses a 1/4" air port.
An external stop screw shortens the extend stroke by up to 40 mm on-site, but it only trims the forward end position and does not lock the mid-stroke. This SKU has no magnet, so it cannot take CMSG, DMSG, or EMSG sensors; you would need the -S variant for sensing.
