About the Airtac MIJ Adjustable Cylinder MIJ32X450-50S
Dial in a precise forward end position on-site with the AirTAC MIJ32X450-50S, a round-body stainless mini cylinder featuring a 50 mm external stop screw that shortens the extend stroke from its 450 mm nominal maximum down to 400 mm. Because the adjuster trims only the extend end, the retract stroke remains full. This double-acting actuator delivers robust force, pushing with 402.2 N and pulling with 345.6 N at 0.5 MPa.
The stainless-steel barrel and Ø12 mm piston rod supply mild corrosion and washdown resistance, while the 1/8" port accommodates high airflow for rapid cycling. Equipped with a built-in magnet (-S), it supports CMSG, DMSG, and EMSG sensors for position feedback. It relies on fixed TPU bumper pads to decelerate the stroke end, yielding a safe working load of roughly 241 N (about 60% of the 0.5 MPa push force) or a vertical lift capacity near 20.5 kg with a 2:1 margin.

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 MIJ32X450-50S Is Used
Staged Diverting
Set the extend stop to push cartons precisely to a secondary lane without over-traveling, using the 402.2 N push force to redirect heavy boxes reliably.
Variable Carton Sealing
Adjust the forward end position on the fly to accommodate different box lengths, using the 50 mm trim window to align sealing heads without changing cylinders.
Tolerance Take-Up Stops
Absorb mechanical variances in pallet positioning by fine-tuning the extend stroke, ensuring the 345.6 N pull force retracts the mechanism fully after each cycle.
Is the Airtac MIJ Adjustable Cylinder MIJ32X450-50S the Right Cylinder?
When sizing this 32 mm bore actuator, compare it against adjacent bores: a 25 mm MIJ provides 245.3 N push at 0.5 MPa, whereas a 40 mm MIJ yields 628.3 N. The 50 mm adjustment window is ideal for taking up mechanical tolerances during setup or covering multiple stop positions with a single part number. For mounting, utilize LB foot, FA flange, or TC trunnion brackets, noting that the SDB pivot block is not offered on this adjustable variant.
Remember that the stop screw dictates the end position but functions purely as a mechanical stop, not a mid-stroke lock. The piston will drift if air pressure is lost, so specify an external rod lock or pilot-operated check valve if your application requires strict load holding on the 450 mm travel.
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 MIJ32X450-50S FAQ
At 0.5 MPa it pushes with 402.2 N and pulls with 345.6 N. At 0.7 MPa the push is 563 N and pull is 483.8 N. The theoretical maximum force is 82 kgf at 1.0 MPa. It uses a 1/8" air port and a male M10x1.25 rod thread.
An external stop screw shortens the extend stroke by up to 50 mm on-site, letting you set the exact forward position without swapping parts; the retract stroke remains full. The -S suffix indicates a built-in piston magnet for use with CMSG, DMSG, or EMSG sensors.
