Airtac MIC Cushioned Mini Cylinder MIC20X40CA
The AirTAC Airtac MIC Cushioned Mini Cylinder MIC20X40CA is a genuine double acting + cushion round-body mini air cylinder with a Ø20mm bore and 40mm stroke, 1/8" air ports and a stainless-steel barrel and rod for mildly corrosive environments. Its ISO 6432 mounting interface makes it a compact drop-in for standard mini-cylinder fixtures.

About the Airtac MIC Cushioned Mini Cylinder MIC20X40CA
Delivering 157 N of push force at 0.5 MPa, this double-acting stainless steel round-body mini cylinder brings variable air cushioning to high-speed actuation. The Ø20 mm bore features an 8 mm piston rod, an M8x1.25 male thread, and a 1/8" port. Its stainless barrel and rod shrug off mild corrosion and washdown environments, while the CA rear pivot cover simplifies clevis mounting.
Unlike standard bumper models, the MIC series integrates a needle-set air cushion at both ends to decelerate the load smoothly at stroke extremes, reducing noise and mechanical shock. This non-magnet SKU cannot host position sensors; adding the -S option enables CMSG, DMSG, or EMSG switches. For vertical loads, expect a safe working lift of about 8 kg with a 2:1 margin.

Where the Airtac MIC Cushioned Mini Cylinder MIC20X40CA Is Used
Package Diverting
Snaps a lightweight gate at high speed to sort small parcels, relying on the adjustable cushions to prevent end-of-stroke slamming.
Small Part Ejection
Pushes machined components out of a fixture using 157 N of force, absorbing the shock of ejection with the dual needle valves.
Flap Folding
Folds carton flaps rapidly on a packaging line where the stainless build resists occasional washdowns and the CA pivot allows angled articulation.
Is the Airtac MIC Cushioned Mini Cylinder MIC20X40CA the Right Cylinder?
When sizing this 20 mm bore, dropping down to the Ø16 version reduces the 0.5 MPa push force to 100.5 N, whereas stepping up to the Ø25 bore raises it to 245.3 N. Choose this 40 mm stroke unit when cycle speeds demand the adjustable end-cushions to prevent harsh impacts. It conforms to the ISO 6432 mounting interface for straightforward bracket interchangeability.
Note that the air cushion only decelerates the piston near the stroke end and does not function 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 configuration lacks the -S magnet, it cannot support magnetic sensing.
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 MIC20X40CA FAQ
This double-acting cylinder uses a 1/8" port. It generates 157 N push and 131.9 N pull at 0.5 MPa, 219.8 N push and 184.7 N pull at 0.7 MPa, with a theoretical maximum force of 32 kgf at 1.0 MPa.
No, this specific SKU does not include a magnet and cannot host CMSG, DMSG, or EMSG switches. You must select the -S variant to enable magnetic position sensing.
