About the Airtac MICJ Adjustable Mini Cylinder MICJ32X400-30S
Dial in a precise forward stop on-site with the AirTAC MICJ32X400-30S, a stainless-steel round-body mini cylinder featuring a 30 mm adjustable extend stroke. An external screw trims the forward end position down from the 400 mm nominal maximum, letting you set exact endpoints without swapping hardware. The built-in piston magnet (-S) supports CMSG, DMSG, and EMSG sensors for position detection.
This double-acting actuator delivers 402.2 N of push force at 0.5 MPa and uses a needle-set variable air cushion at both ends to absorb high-speed impact. With a practical safe working load of roughly 241 N (about 60% of the 0.5 MPa push figure), it handles substantial mass. The 1/8" port and stainless construction provide mild washdown resistance for demanding industrial environments.

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 MICJ32X400-30S Is Used
Heavy Cart Diversion
Pushes loaded carts at high speed onto a secondary line, using the 30 mm extend stop to dial in the exact contact position while the dual air cushions absorb the 402.2 N impact.
Large Case Flapping
Closes heavy corrugated boxes on a high-speed line, relying on the needle-set cushion to prevent end-of-stroke shock and the magnet for precise timing.
Pallet Stopper Gate
Acts as an adjustable physical stop for incoming pallets, trimming the forward position by up to 30 mm to align with varying load widths without changing mounts.
Is the Airtac MICJ Adjustable Mini Cylinder MICJ32X400-30S the Right Cylinder?
When sizing this 32 mm bore, stepping down to a 25 mm bore drops the 0.5 MPa push force to 245.3 N, while stepping up to a 40 mm bore increases it to 628.3 N. Choose this model when you need those 402.2 N of thrust combined with a dialed-in extend stop and high-speed cushioning for heavy positioning tasks. Mount via LB foot, FA flange, or TC trunnion (the SDB pivot-block is not offered on this adjustable variant), and use the -S magnet for electronic or reed switches.
Remember that the adjustable stop screw and air cushion only set the end position and decelerate the piston near stroke end. They do not function as a mid-stroke lock. If your application must hold a vertical load on air loss, add an external rod lock or pilot-operated check valve.
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 MICJ32X400-30S FAQ
This 32 mm bore cylinder uses a 1/8" port and a M10x1.25 male rod thread. It generates 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 30 mm (usable extend 370-400 mm), while retract remains full. Needle-set variable air cushions at both ends soak up high-speed shock. The -S suffix means it has a built-in magnet for CMSG/DMSG/EMSG sensors.
