About the Airtac MIJ Adjustable Cylinder MIJ40X50-10S
Dial in your forward end position on-site with the AirTAC MIJ40X50-10S, a round-body stainless mini cylinder featuring a 10mm adjustable extend window. An external stop screw lets you trim the forward stroke from 50mm down to 40mm, absorbing setup tolerances without changing the cylinder. Retract remains full length. Built with a stainless-steel barrel and Ø16mm rod, it resists mild corrosion and washdown environments.
This double-acting 40mm bore delivers serious force for a mini cylinder, pushing 628.3N and pulling 527.8N at 0.5MPa. The 1/4" port and M12x1.25 male rod thread handle high airflow, while fixed TPU bumper pads decelerate the stroke end. Because this SKU includes the -S magnet, it supports CMSG, DMSG, and EMSG sensors for position confirmation.

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 MIJ40X50-10S Is Used
Heavy Clamping Station
The 10mm extend adjustment lets operators fine-tune the clamp contact point to compensate for varying part thicknesses without retooling.
Staged Divert Gate
Act as a heavy-duty diverter on a packaging line. The external stop screw allows you to shorten the extend stroke by up to 10mm to accommodate different box widths on the fly.
Vertical Lift Stop
The adjustable forward stop ensures the load reaches the exact transfer height, while the -S magnet confirms the extend position.
Is the Airtac MIJ Adjustable Cylinder MIJ40X50-10S the Right Cylinder?
When sizing this 40mm bore, compare it directly to the adjacent MIJ options. Stepping down to a 32mm bore drops your 0.5MPa push force to 402.2N, whereas this 40mm unit provides 628.3N. There is no larger standard MIJ bore, making this the top force choice in the series. The 10mm extend adjuster is ideal for changeover jobs where you need one part number to cover several slightly different forward stops.
Remember that the stop screw sets the end position but acts purely as a mechanical stop, not a mid-stroke lock. If air pressure drops, the piston will drift and cannot hold a load. For suspended or vertical loads that must remain fixed on air loss, add an external rod lock or pilot-operated check valve. Mount this cylinder using LB foot, FA flange, or TC trunnion brackets, plus CA, U, R, or CM back covers. Note that the SDB pivot block 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 MIJ40X50-10S FAQ
The theoretical maximum force is 128.1kgf at 1.0MPa.
An external stop screw shortens the extend stroke by up to 10mm on-site, giving a usable forward range of 40-50mm; retract remains full. The -S suffix means it has a built-in piston magnet for CMSG, DMSG, or EMSG sensors. The stainless build resists mild corrosion.
