About the Airtac MIJ Adjustable Cylinder MIJ32X400-50
Dial in a precise forward end position on-site with the AirTAC MIJ32X400-50, a round-body stainless mini cylinder featuring a 50 mm extend-stroke adjustment window. Rather than swapping components to hit a new stop, you simply turn the external screw to shorten the forward stroke from its 400 mm nominal length down to 350 mm, while retract remains full.
Built with a stainless-steel barrel and piston rod for mild corrosion resistance, this double-acting unit delivers 402.2 N of push force at 0.5 MPa. That translates to a safe working load of roughly 241 N, or a vertical lift capacity of about 20.5 kg with a 2:1 safety margin. It uses a 1/8" port, runs at 30-800 mm/s, and relies on fixed TPU bumper pads to decelerate the stroke end. Note that Ø32 is a non-ISO-6432 size.

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 Ø32 bore is a larger, non-ISO-6432 size.
Theoretical Output Force (Ø32mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 402 N | 346 N |
| 0.7 MPa | 563 N | 484 N |
| Max (@1.0 MPa) | 82 kgf | |
Actual usable force is lower than theoretical due to friction and back-pressure. Size with a safety margin.

Where the Airtac MIJ Adjustable Cylinder MIJ32X400-50 Is Used
Staged Diverter Pusher
Use the 50 mm on-site adjustment to alter the extend stroke on a sorting line, accommodating different package depths without swapping out the entire cylinder.
Pallet Changeover Stop
Leverage the 402.2 N push force to halt heavy pallets, dialing the external screw to fine-tune the stopping distance for various load tolerances.
Carton Flap Folder
Set exact forward positions for folding varied carton sizes, using the fixed TPU bumpers to soften the end of the 400 mm stroke during high-speed cycling.
Is the Airtac MIJ Adjustable Cylinder MIJ32X400-50 the Right Cylinder?
This Ø32 bore provides substantial thrust, pushing 402.2 N at 0.5 MPa. If your application needs less force, stepping down to the Ø25 MIJ drops the push force to 245.3 N; conversely, moving up to the Ø40 MIJ increases it to 628.3 N. The 50 mm adjuster is invaluable for taking up mechanical tolerances during setup or covering multiple intermediate stop positions without changing the part number.
Keep in mind the stop screw sets the end position but is not a mid-stroke lock; the piston will drift on air loss, so fit an external rod lock or pilot check valve for held loads. Mount via LB foot, FA flange, or TC trunnion (SDB is unavailable on this adjustable variant). Because this SKU lacks the -S magnet, it cannot accept CMSG, DMSG, or EMSG sensors.
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 MIJ32X400-50 FAQ
This double-acting cylinder uses a 1/8" port and generates 402.2 N push / 345.6 N pull at 0.5 MPa, and 563 N push / 483.8 N pull at 0.7 MPa. The theoretical maximum force is 82 kgf at 1.0 MPa.
An external stop screw shortens the extend stroke by up to 50 mm on-site, but retract remains full. This SKU has no magnet, so it cannot take CMSG/DMSG/EMSG sensors; you need the -S variant for sensing.
