About the Airtac MICJ Adjustable Mini Cylinder MICJ32X400-20S
Dial in a precise forward stop on-site with the AirTAC MICJ32X400-20S, a round-body stainless-steel mini cylinder that shortens the extend stroke by up to 20 mm via an external screw. The usable extend range becomes 380-400 mm, letting you trim the forward end position without swapping hardware. A needle-set adjustable air cushion at both ends soaks up high-speed shock, while the stainless barrel and rod resist mild corrosion and washdown environments.
This double-acting Ø32 bore delivers 402.2 N of push force at 0.5 MPa, yielding a safe working load of about 241 N or a vertical lift capacity near 20.5 kg with a 2:1 margin. It features a 1/8" port, a Ø12 mm piston rod, and a built-in magnet (-S) for CMSG, DMSG, or EMSG sensors. Note that Ø32 is a non-ISO-6432 size, and the stop screw only sets the end position—it is not a mid-stroke lock.

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 MICJ32X400-20S Is Used
Long-Reach Diverting
Pushes packages at the end of a 400 mm stroke, using the 20 mm extend adjuster to fine-tune the contact point without moving the bracketry.
High-Speed Carton Sealing
Cycles rapidly to fold flaps; the dual adjustable air cushions absorb the shock of the 402.2 N extend force to prevent denting the cardboard.
Vertical Lift Gates
Lifts roughly 20.5 kg access panels using the 0.5 MPa push force, relying on the needle cushions to soften the upward stop.
Is the Airtac MICJ Adjustable Mini Cylinder MICJ32X400-20S the Right Cylinder?
When sizing this unit, step down to a Ø25 bore if your load is lighter, as it provides 245.3 N push at 0.5 MPa. If you need more power, the Ø40 bore jumps to 628.3 N push at 0.5 MPa. The MICJ32X400-20S shines in fast set-position moves where the 20 mm extend adjuster and dual air cushions prevent end-of-stroke slamming. For vertical loads, remember the piston drifts on air loss; the cushion only decelerates near the end and does not act as a brake, so add an external pilot check valve to hold the load.
Mounting options include LB foot, FA flange, and TC trunnion, but the SDB pivot-block is not available on this adjustable-stroke variant. Because this SKU includes the -S magnet, you can directly mount CMSG, DMSG, or EMSG sensors for position feedback.
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 MICJ32X400-20S FAQ
This double-acting cylinder uses a 1/8" port and generates 402.2 N push and 345.6 N pull at 0.5 MPa. At 0.7 MPa it provides 563 N push and 483.8 N pull. The theoretical maximum force is 82 kgf at 1.0 MPa.
An external screw shortens the extend stroke by up to 20 mm (usable range 380-400 mm), while needle valves adjust the air cushion at both ends to decelerate high-speed impacts. The -S magnet enables CMSG/DMSG/EMSG sensors. The stop screw and cushion do not lock or hold the load on air loss; use an external rod lock for that.
