About the Airtac MIJ Adjustable Cylinder MIJ40X100-40S
Dial in a precise forward end position on the fly with the AirTAC MIJ40X100-40S, a round-body stainless mini cylinder built for heavy-duty pneumatics. An external stop screw lets you shorten the extend stroke by up to 40 mm on-site, giving a usable forward range of 60 to 100 mm without swapping parts. Retract remains at the full 100 mm.
The stainless-steel barrel and Ø16 mm piston rod shrug off mild corrosion and washdown environments. A 1/4" port and M12×1.25 male rod thread handle the air and mechanical coupling for this non-ISO-6432 40 mm class. Because this SKU includes the -S magnet, it supports CMSG, DMSG, and EMSG sensors for end-of-stroke detection. Fixed TPU bumper pads decelerate the stroke ends, operating reliably at speeds of 30-800 mm/s across a -20 to +70 °C 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 MIJ40X100-40S Is Used
Multi-Position Pressing
Perform light-duty pressing or stamping tasks where the end position requires on-the-fly adjustment, using the bumper pads to soften the final impact.
Pallet Staging Stops
Act as an adjustable physical stop for pallets or heavy totes, leveraging the stainless build to survive washdown areas in logistics facilities.
Is the Airtac MIJ Adjustable Cylinder MIJ40X100-40S the Right Cylinder?
When sizing this 40 mm bore, compare it directly against the adjacent MIJ32. If your application demands less force, step down to the 32 mm bore; there is no larger standard MIJ bore above 40 mm. The 40 mm adjuster window is perfect for taking up mechanical tolerances or staging feeds during changeovers.
Remember that the external stop screw sets the extend end position but acts purely as a physical stop, not a mid-stroke lock. The piston will drift if air pressure is lost, so fit an external rod lock or pilot-operated check valve for holding suspended loads. For mounting, utilize LB foot, FA flange, or TC trunnion brackets, plus CA, U, R, or CM back covers. Note that the SDB pivot block is not offered 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 MIJ40X100-40S FAQ
The theoretical maximum force is 128.1 kgf at 1.0 MPa.
The external stop screw shortens the extend stroke by up to 40 mm (usable range 60-100 mm); retract remains full. The -S suffix denotes a built-in piston magnet for CMSG, DMSG, or EMSG sensors. The screw is a physical stop, not a mid-stroke lock.
