About the Airtac MIC Cushioned Mini Cylinder MIC40X450U
Delivering 628.3 N of push force at 0.5 MPa, this double-acting round-body mini cylinder handles heavy-duty tasks within a 450 mm stroke. The stainless-steel barrel and rod resist mild corrosion and washdown environments. A 1/4" port feeds the 16 mm piston rod, yielding a theoretical maximum output of 128.1 kgf at 1.0 MPa.
The defining feature is the adjustable air cushion at both ends, letting you dial in needle valves to absorb high-speed end-of-stroke shock. This protects your payload and cuts noise. As a practical buyer insight, it yields a safe working load of roughly 377 N, lifting about 32 kg vertically with a 2:1 margin. Note this SKU lacks a magnet, so it cannot take position sensors.

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 Ø40 bore is a larger, non-ISO-6432 size.
Theoretical Output Force (Ø40mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 628 N | 528 N |
| 0.7 MPa | 880 N | 739 N |
| Max (@1.0 MPa) | 128 kgf | |
Actual usable force is lower than theoretical due to friction and back-pressure. Size with a safety margin.

Where the Airtac MIC Cushioned Mini Cylinder MIC40X450U Is Used
Heavy Cart Diversion
Pushes loaded pallets or heavy cartons across a transfer line using its 628.3 N thrust, relying on the cushion to stop the 450 mm stroke gently.
Vertical Press Lowering
Lowers a 30 kg tooling head smoothly; the adjustable needle absorbs the downward momentum without slamming the base.
Washdown Gate Actuation
Operates a stainless-steel access door in a humid packing area, where the corrosion-resistant round-body build prevents rust.
Is the Airtac MIC Cushioned Mini Cylinder MIC40X450U the Right Cylinder?
When sizing this 40 mm bore, stepping down to the MIC32 bore drops the 0.5 MPa push force to 402.2 N, while no larger MIC bore exists. Choose this 450 mm stroke model for moving heavier masses where the adjustable cushion is essential to prevent harsh impacts at high cycling speeds. The U-style back cover provides a 90-degree mounting orientation for compact footprints.
Remember that the air cushion only decelerates the piston near the stroke end; it does not act as a brake. If your application must hold a load vertically during air loss, install an external rod lock or pilot-operated check valve. Because this specific SKU has no -S magnet, it cannot support CMSG, DMSG, or EMSG switches.
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 MIC Cushioned Mini Cylinder MIC40X450U FAQ
This 40 mm bore cylinder uses a 1/4" port and a 16 mm rod. It generates 628.3 N push and 527.8 N pull at 0.5 MPa, or 879.6 N push and 738.9 N pull at 0.7 MPa. The theoretical maximum force is 128.1 kgf at 1.0 MPa.
No, this specific SKU does not include a magnet. You must choose an -S variant to use CMSG, DMSG, or EMSG switches. The adjustable air cushion and stainless build are still present, but position sensing is not supported on this base model.
