About the Airtac MIJ Adjustable Cylinder MIJ32X450-30S
Dial in a precise forward end position on the factory floor with the AirTAC MIJ32X450-30S, a round-body stainless mini cylinder built for double-acting operation. An external stop screw lets you shorten the extend stroke by up to 30 mm on site, yielding a usable forward travel of 420 to 450 mm without swapping parts. The retract stroke remains full length, and the screw simply sets the end stop rather than acting as a mid-stroke lock.
This Ø32 bore delivers substantial muscle, pushing with 402.2 N and pulling with 345.6 N at 0.5 MPa. For practical sizing, that translates to a safe working load of roughly 241 N, or vertically lifting about 20.5 kg with a 2:1 safety margin. The riveted stainless-steel barrel and Ø12 mm rod resist mild corrosion and washdown environments. Fitted with a 1/8" port and a male M10x1.25 rod thread, it runs on filtered air at 30-800 mm/s. Because this SKU carries the -S suffix, a built-in piston magnet is present, allowing you to mount CMSG, DMSG or EMSG position switches for electronic feedback.

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 MIJ32X450-30S Is Used
Staged Diverting Gate
Trimming the extend stroke by up to 30 mm allows a diverting arm to hit two distinct package sizes on a single conveyor line without physically changing out the actuator.
Fill Head Positioning
With 402.2 N of push force, this cylinder lowers a filling nozzle into various container heights, using the external stop screw to set the precise 420-450 mm depth and prevent splash.
Tolerance Take-Up Pusher
Ideal for pushing heavy pallets or totes, where the on-site adjuster absorbs mechanical tolerances and ensures the pusher bottoms out consistently at the required end point.
Is the Airtac MIJ Adjustable Cylinder MIJ32X450-30S the Right Cylinder?
When sizing this unit, verify your force needs against both adjacent bores. If you require less push, the Ø25 MIJ variant provides 245.3 N at 0.5 MPa; if your load is heavier, stepping up to the Ø40 MIJ yields 628.3 N at the same pressure. The 30 mm adjustment window on this model is invaluable for taking up mechanical tolerances during setup or covering multiple stop positions in a changeover fixture using one part number.
Keep in mind that a standard cylinder does not hold position upon air loss, as the piston will drift and the fixed TPU bumper pads only decelerate the stroke end. To suspend a vertical load safely, install an external rod lock or a pilot-operated check valve. For mounting, you can utilize LB foot, FA flange or TC trunnion brackets alongside CA, U, R or CM back covers, but note that the SDB pivot block is not offered on this adjustable-stroke series.
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 MIJ32X450-30S FAQ
This Ø32 bore cylinder features a 1/8" air port and a male M10x1.25 rod thread. At 0.5 MPa it pushes with 402.2 N and pulls with 345.6 N. At 0.7 MPa, push increases to 563 N and pull to 483.8 N. The theoretical maximum force is 82 kgf at 1.0 MPa.
An external stop screw shortens the extend stroke by up to 30 mm on site, letting you fine-tune the forward end position without affecting the full retract stroke. The -S suffix means a piston magnet is built-in, enabling CMSG, DMSG or EMSG sensors. The stop screw is an end-position setter, not a mid-stroke lock.
