About the Airtac MIJ Adjustable Cylinder MIJ40X160-40
Dialing in a precise forward end position on-site is effortless with this 40 mm bore, double-acting round-body mini cylinder, because an external stop screw shortens the extend stroke by up to 40 mm (yielding a usable 120-160 mm forward travel) without swapping parts. The stainless-steel barrel and piston rod supply mild corrosion and washdown resistance for demanding environments.
This non-ISO-6432 unit features a 1/4" port, a Ø16 mm rod with an M12x1.25 male thread, and fixed TPU bumper pads to decelerate the stroke end. Note this SKU lacks a magnet and cannot accept position 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 MIJ40X160-40 Is Used
Variable Depth Carton Sealer
Tunes the extend stroke on the fly to match different box depths, using the 527.8 N retract force to consistently pull the sealing head back to the exact starting point.
Is the Airtac MIJ Adjustable Cylinder MIJ40X160-40 the Right Cylinder?
The 40 mm adjuster is perfect for taking up mechanical tolerances or staging feeds during setup. Remember the stop screw only sets the extend end position; it is not a mid-stroke lock, and the piston will drift on air loss. Use an external rod lock or pilot check valve for held loads.
Mounting options include LB foot, FA flange, and TC trunnion brackets (SDB pivot-block is not available). Because this specific SKU is non-magnetic, it cannot support CMSG, DMSG, or EMSG sensors; select the -S variant if you require 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 MIJ40X160-40 FAQ
This 40 mm bore cylinder uses a 1/4" port. The theoretical maximum force is 128.1 kgf at 1.0 MPa.
An external stop screw shortens the extend stroke by up to 40 mm, letting you set the exact forward end position; retract remains full. It uses fixed TPU bumper pads to decelerate the stroke end, not an adjustable air cushion. This SKU has no magnet, so it cannot take sensors.
