About the Airtac MIJ Adjustable Cylinder MIJ32X125-20S
Dialing in a precise forward end position on-site is effortless with this stainless-steel round-body mini cylinder, because an external stop screw lets you shorten the extend stroke by up to 20 mm without swapping parts. As a double-acting actuator, it delivers substantial thrust—pushing with 402.2 N and pulling with 345.6 N at 0.5 MPa—making it suitable for heavier tooling tasks.
Built with a corrosion-resistant stainless barrel and rod, it handles mild washdown environments while operating at speeds of 30-800 mm/s. The included piston magnet (-S) supports CMSG, DMSG, and EMSG sensors for position confirmation. It uses a 1/8" port and a Ø12 mm rod, and relies on fixed TPU bumper pads to decelerate at the stroke ends.

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 MIJ32X125-20S Is Used
Staged Diverter Pusher
Adjusts the extend stop by up to 20 mm to deflect heavy cartons of varying widths onto different conveyor lanes without changing the cylinder.
Multi-Depth Clamping
Provides up to 402.2 N of clamping force at 0.5 MPa, with an on-site adjustable forward position to secure parts of different heights in the same fixture.
Variable Stroke Sealing
Uses the 20 mm extend adjustment to tune the pressing depth of sealing jaws for different package thicknesses, ensuring consistent results.
Is the Airtac MIJ Adjustable Cylinder MIJ32X125-20S the Right Cylinder?
When sizing this actuator, consider that it provides a safe working load of roughly 241 N (about 60% of its 0.5 MPa push force), translating to a vertical lift capacity of approximately 20.5 kg with a 2:1 safety margin. If your application requires less force, stepping down to a Ø25 bore yields 245.3 N push at 0.5 MPa; if you need more power, the Ø40 bore offers 628.3 N. The 20 mm adjustment window is ideal for taking up mechanical tolerances during setup or accommodating multiple stopping points with a single part number.
Remember that the stop screw only trims the extend end position—it is not a mid-stroke lock or brake. The piston will drift if air pressure is lost, so fit an external rod lock or pilot-operated check valve for suspended loads. For mounting, you can use LB foot, FA flange, or TC trunnion brackets (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 MIJ32X125-20S 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 20 mm (usable extend 105-125 mm), while the retract stroke remains full. The -S suffix indicates a built-in piston magnet for CMSG, DMSG, or EMSG sensors; a SKU without S cannot accept them.
