About the Airtac MIJ Adjustable Cylinder MIJ32X400-20
Dial in a precise forward end position on-site with the AirTAC MIJ32X400-20, a round-body stainless mini cylinder featuring a 20 mm extend-stroke adjustment window. Rather than stocking multiple cylinders to cover slight stroke variations, a single external stop screw lets you trim the usable forward travel down to 380 mm, while retract remains full.
Built with a stainless-steel barrel and Ø12 mm piston rod, this double-acting unit handles mild corrosion and washdown environments while delivering 402.2 N of push force at 0.5 MPa. It uses a 1/8" port and fixed TPU bumper pads to decelerate the stroke end. As a non-magnet SKU, it cannot accept position sensors; adding the -S option enables CMSG, DMSG, or EMSG switches.

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 MIJ32X400-20 Is Used
Staged Diverting
Trim the 400 mm extend stroke by up to 20 mm to align a diverter arm precisely with varying package sizes on a washdown conveyor line.
Tolerance Take-Up
Use the external stop nut to dial in the exact clamping position on a machining fixture, absorbing part tolerances without swapping actuators.
Changeover Pusher
Adjust the forward end position on-site for product changeovers, letting one cylinder handle multiple box formats in a packaging cell.
Is the Airtac MIJ Adjustable Cylinder MIJ32X400-20 the Right Cylinder?
When sizing this 32 mm bore, the adjacent MIJ25 generates 245.3 N of push force at 0.5 MPa, whereas the larger MIJ40 provides 628.3 N. The MIJ32X400-20 hits a sweet spot at 402.2 N push (345.6 N pull) at 0.5 MPa, translating to a safe working load of roughly 241 N or a 20.5 kg vertical lift with a 2:1 margin. The 20 mm adjuster is ideal for taking up mechanical tolerances during setup or accommodating multiple part stops without changing the actuator.
Mounting options include LB foot, FA flange, and TC trunnion brackets, plus CA, U, R, and CM back covers, but note that the SDB pivot block is not available on this adjustable variant. Because this SKU lacks a magnet, it cannot support sensing. Furthermore, the stop screw sets the end position but does not function as a mid-stroke lock; the piston will drift on air loss, so fit an external rod lock or pilot check valve if you need to hold a suspended load.
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 MIJ32X400-20 FAQ
This 32 mm bore 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 on-site, setting the forward end position without affecting full retract. The stop screw is not a mid-stroke lock, so the piston drifts on air loss. This non-magnet SKU cannot take sensors; the -S variant adds a magnet for CMSG/DMSG/EMSG switches.
