About the Airtac MIJ Adjustable Cylinder MIJ32X400-40
Dial in a precise forward end position on-site with the AirTAC MIJ32X400-40, a round-body stainless-steel mini cylinder built for double-acting operation. An external stop screw lets you shorten the extend stroke by up to 40 mm, giving a usable forward range of 360 to 400 mm without swapping parts. The retract stroke remains full length, and the screw only sets the end stop, functioning as a bumper rather than a mid-stroke lock.
The 32 mm bore uses a 1/8" port and a 12 mm rod to deliver 402.2 N of push force at 0.5 MPa, yielding a safe working load of roughly 241 N or a 20.5 kg vertical lift with a 2:1 margin. Fixed TPU bumper pads decelerate the stroke end, and the stainless barrel and rod resist mild corrosion. Note that Ø32 is a non-ISO-6432 size, and this specific SKU lacks a magnet, so it cannot host CMSG, DMSG, or EMSG sensors.

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 MIJ32X400-40 Is Used
Sorter Diverter Alignment
Trim the extend stroke up to 40 mm to perfectly match diverter gate angles on a packaging line, using the 402.2 N push force to positively redirect heavier cartons.
Pallet Stop Calibration
Adjust the forward stop on-site to accommodate different pallet widths without changing hardware, relying on the 241 N safe working load to halt incoming pallets smoothly.
Press Tooling Setup
Fine-tune the 360 to 400 mm extend position to take up tolerance stacks in multi-part assemblies, leveraging the 20.5 kg vertical lift capacity for component placement.
Is the Airtac MIJ Adjustable Cylinder MIJ32X400-40 the Right Cylinder?
When sizing this unit, consider the next bore down (Ø25, 245.3 N push @0.5 MPa) for lighter loads, or step up to the Ø40 (628.3 N push @0.5 MPa) if your application exceeds the 241 N safe working load. The 40 mm adjustment window is ideal for taking up mechanical tolerances or staging feeds during changeovers. For mounting, you can use LB foot, FA flange, or TC trunnion brackets, but the SDB pivot block is not available on this adjustable variant.
Remember that this cylinder does not hold position on air loss; the piston will drift if pressure drops, so install an external rod lock or pilot check valve for suspended loads. Because this SKU is not the -S magnet version, it cannot support position sensing. Operating speed spans 30 to 800 mm/s.
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 MIJ32X400-40 FAQ
This 32 mm bore cylinder features a 1/8" port and a 12 mm rod. It generates 402.2 N push and 345.6 N pull at 0.5 MPa, increasing to 563 N push and 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 40 mm on-site, setting the forward end position without affecting the full retract stroke. This screw is not a mid-stroke lock; the cylinder drifts on air loss, so use an external rod lock for suspended loads. Additionally, this non-S SKU lacks a magnet and cannot support sensors.
