About the Airtac MIC Cushioned Mini Cylinder MIC40X20U
Delivering 628.3 N of push force at 0.5 MPa, this double-acting stainless steel round-body mini cylinder handles heavy-duty actuation within a compact footprint. The 40 mm bore pairs a 16 mm piston rod with a 1/4" port and a U-style 90-degree rear cover for flexible mounting orientation. Because this specific SKU lacks the -S magnet, it cannot accept CMSG, DMSG, or EMSG position switches.
A variable air cushion at both ends lets you dial in the needle valve to decelerate heavy loads smoothly at high speeds, reducing shock and noise compared to fixed bumper designs. In practical terms, it provides a safe working load of roughly 377 N, meaning it can lift about 32 kg vertically with a 2:1 safety margin. The stainless barrel and rod resist mild corrosion and washdown environments.

Where the Airtac MIC Cushioned Mini Cylinder MIC40X20U Is Used
Heavy Package Diversion
Pushes heavy cartons at high speed across transfer lines where the adjustable air cushion prevents harsh slamming at the 20 mm stroke end.
Compact Press Operation
Applies a steady 628.3 N pressing force for sealing or compacting tasks, utilizing the 1/4" port for rapid fill and exhaust.
Pallet Stop Gate
Acts as a robust stopper for heavier pallets, relying on the stainless build to endure mildly humid or washdown warehouse environments.
Is the Airtac MIC Cushioned Mini Cylinder MIC40X20U the Right Cylinder?
When sizing this 40 mm bore, dropping down to the MIC32 yields 402.2 N of push force at 0.5 MPa, while the MIC40 is the largest available bore in this series with no larger option. The adjustable end cushions are essential if you are moving heavier masses at high cycle rates, as they prevent harsh end-of-stroke impacts. Remember that the air cushion only decelerates the piston near the stroke end; it does not function as a lock or brake. If your application must hold a load vertically during air loss, install an external rod lock or a pilot-operated check valve.
The U-style back cover accommodates 90-degree mounting requirements. Since this base model has no internal magnet, it cannot support sensing switches; you must specify an -S variant if you require 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 MIC Cushioned Mini Cylinder MIC40X20U FAQ
This 40 mm bore cylinder features a 1/4" port and a 16 mm rod. It generates 628.3 N push and 527.8 N pull at 0.5 MPa, 879.6 N push and 738.9 N pull at 0.7 MPa, with a theoretical maximum force of 128.1 kgf at 1.0 MPa.
No, this specific SKU does not include the -S magnet, so it cannot accept CMSG, DMSG, or EMSG switches. You must select an -S variant for sensing capabilities. The adjustable air cushion at both ends functions only to decelerate the load near stroke end, not to hold it.
