About the Airtac MICJ Adjustable Mini Cylinder MICJ32X75-20S
Dial in a precise forward stop on site with the AirTAC MICJ32X75-20S, a stainless-steel round-body mini cylinder featuring a 20 mm adjustable extend stroke. An external stop screw trims the extend end position down from the 75 mm nominal maximum, while a needle-set adjustable air cushion at both ends soaks up high-speed shock. As a double-acting actuator with a built-in magnet (-S), it generates 402.2 N of push force at 0.5 MPa.
The Ø32 mm bore uses a 1/8" port and a 12 mm piston rod to deliver robust performance without tie-rod or profile construction. Because it is a non-ISO-6432 size, it functions purely as a heavy-duty round-body mini cylinder. The stainless barrel and rod resist mild corrosion and washdown environments. For sizing, this yields a safe working load of about 241 N, or roughly 20.5 kg of vertical lift with a 2:1 safety margin.

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 MICJ32X75-20S Is Used
Divert Gate Actuation
Shifts a conveyor sorting gate with 402.2 N push force, using the 20 mm extend adjustment to fine-tune the gate angle and the air cushion to absorb the impact of high-speed 30-800 mm/s cycles.
Carton Flap Folding
Drives a folding arm on a packaging line, relying on the stainless construction for washdown resistance and the needle-set cushion to prevent denting cardboard at the end of the 75 mm stroke.
Pallet Stopper Block
Acts as an adjustable stop for heavy pallets, trimming the extend position by up to 20 mm to align pallets precisely while the -S magnet triggers a DMSG sensor to confirm the block is deployed.
Is the Airtac MICJ Adjustable Mini Cylinder MICJ32X75-20S the Right Cylinder?
When sizing this actuator, step down to the Ø25 bore for 245.3 N push at 0.5 MPa if your load is lighter, or step up to the Ø40 bore for 628.3 N when you need more thrust. The MICJ32X75-20S shines in fast set-position moves where the 20 mm extend adjuster and dual air cushions prevent harsh impacts. Mount using LB foot, FA flange, or TC trunnion brackets, noting the SDB pivot block is not offered on this adjustable variant. The included -S magnet enables CMSG, DMSG, or EMSG sensors for position detection.
Remember that the stop screw sets only the end position and the air cushion merely decelerates near stroke end. This cylinder does not hold position or lock the load on air loss, as the piston will drift. For suspended or vertical loads that must stay put without air pressure, install an external rod lock or a 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 MICJ32X75-20S FAQ
This double-acting cylinder uses a 1/8" port and delivers 402.2 N push and 345.6 N pull at 0.5 MPa. At 0.7 MPa, push is 563 N and pull is 483.8 N. The theoretical maximum force is 82 kgf at 1.0 MPa.
An external screw shortens the extend stroke by up to 20 mm, giving a usable forward range of 55-75 mm, while the needle-set air cushion decelerates the piston at both ends. The -S magnet allows CMSG/DMSG/EMSG sensors. The cushion only decelerates and does not lock; the piston drifts on air loss, so use an external rod lock for holding.
