About the Airtac MICJ Adjustable Mini Cylinder MICJ32X400-20
Dial in a precise forward stop on site with the AirTAC MICJ32X400-20, a stainless-steel round-body mini cylinder built for double-acting service. An external screw trims the extend end by up to 20 mm, giving a usable forward range of 380-400 mm, while a needle-set adjustable air cushion at both ends soaks up high-speed shock. The 1/8" port and M10x1.25 male rod thread handle serious pneumatic work, delivering 402.2 N of push force at 0.5 MPa.
This 32 mm bore generates 563 N of push at 0.7 MPa, translating to a safe working load of roughly 241 N or a vertical lift of about 20 kg with a 2:1 margin. The stainless barrel and piston rod resist mild corrosion and washdown environments. Note this non-magnetic SKU cannot host CMSG, DMSG, or EMSG sensors; adding the -S magnet variant enables that capability.

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 MICJ Adjustable Mini Cylinder MICJ32X400-20 Is Used
Package Diverting Gate
Shifts a heavy sorting gate on a 400 mm run. The 20 mm extend stop dials in the exact open position, while the air cushion absorbs the impact of fast 402.2 N actuation.
Vertical Pallet Stop
Lifts a 20 kg fixture securely. The adjustable forward stop ensures precise alignment at the end of the 380-400 mm stroke without mechanical hard stops.
Film Roll Tensioner
Pushes a tensioning arm with 563 N at 0.7 MPa. The needle-set air cushion decelerates the 32 mm rod smoothly at high cycling speeds to protect the film web.
Is the Airtac MICJ Adjustable Mini Cylinder MICJ32X400-20 the Right Cylinder?
Size this 32 mm bore against the adjacent options: step down to the 25 mm model for 245.3 N push at 0.5 MPa, or step up to the 40 mm bore for 628.3 N if your payload exceeds the 241 N safe working load of this unit. The 20 mm extend adjuster plus dual air cushions shine in fast set-position moves where you must tune the exact forward stop and control end impact without swapping hardware.
Remember the stop screw sets the end position but is not a mid-stroke lock; the piston will drift on air loss, so fit an external rod lock or pilot check valve for held loads. Mount using LB foot, FA flange, or TC trunnion (SDB pivot-block is unavailable here). This SKU lacks a magnet, so order the -S variant if you require position sensing.
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 MICJ Adjustable Mini Cylinder MICJ32X400-20 FAQ
This 32 mm bore cylinder features a 1/8" port and an M10x1.25 male rod thread. It delivers 402.2 N push and 345.6 N pull at 0.5 MPa, 563 N push and 483.8 N pull at 0.7 MPa, with a theoretical maximum force of 82 kgf at 1.0 MPa.
An external screw shortens the extend stroke by up to 20 mm, letting you set the exact forward end position on site. The adjustable air cushion at both ends decelerates the piston near stroke ends to absorb high-speed shock. This non-magnetic SKU cannot take sensors; the -S variant adds a magnet for CMSG/DMSG/EMSG switches.
