Airtac MIC Cushioned Mini Cylinder MIC20X25CA
The AirTAC Airtac MIC Cushioned Mini Cylinder MIC20X25CA is a genuine double acting + cushion round-body mini air cylinder with a Ø20mm bore and 25mm 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 MIC20X25CA
Delivering 157 N of push force at 0.5 MPa, this stainless-steel round-body mini cylinder handles light-duty actuation with precision. The double-acting design features an adjustable air cushion at both ends, allowing you to tune a needle valve to absorb end-of-stroke shock at high speeds. This protects the load and cuts noise far better than a fixed rubber bumper. Built on the ISO 6432 mounting interface, it drops directly into standard mini-cylinder brackets and clevises.
The Ø20 mm bore uses an M8x1.25 male rod thread and a 1/8" port. With a 25 mm stroke and a CA rear pivot cover, it fits neatly into compact pivot-mount setups. This specific SKU lacks the internal magnet, so it cannot accept CMSG, DMSG, or EMSG position switches; choose the -S variant if you require sensing. For vertical loads, it lifts about 8 kg safely with a 2:1 margin. Note that the cushion only decelerates the piston near the stroke end and does not act as a brake.

Where the Airtac MIC Cushioned Mini Cylinder MIC20X25CA Is Used
Light Parts Ejection
Uses the 157 N push force to knock small plastic parts out of a mold, relying on the tuned air cushion to stop the rod gently without slamming the back cap.
Package Diverting
Pivots via the CA rear clevis to push light cartons on a conveyor at high speed, where the adjustable cushion prevents jarring impacts that could topple the boxes.
Small Component Sorting
Actuates a sorting gate for small electronic components, using the 25 mm stroke to quickly shift the flow path while the needle-set cushion silences the stroke end.
Is the Airtac MIC Cushioned Mini Cylinder MIC20X25CA the Right Cylinder?
If your application needs less force, the smaller MIC16 bore provides 100.5 N of push at 0.5 MPa, though it lacks the adjustable cushion found only on the 16-40 mm series. For heavier payloads, stepping up to the MIC25 bore yields 245.3 N of push force at the same pressure. The adjustable cushion on this MIC20X25CA is essential when cycling at high speeds or moving sensitive masses that would be damaged by sudden stops.
Because this model has no -S magnet, position sensing is impossible without changing the SKU. Furthermore, a standard cylinder does not hold its load if air pressure drops or the valve is centered; the piston will drift. To maintain vertical position on air loss, install an external rod lock or a pilot-operated check valve. Along with the CA pivot cover, you can adapt the mounting using LB foot, FA flange, SDB pivot-block, or TC trunnion accessories.
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 MIC20X25CA FAQ
This double-acting cylinder has a 20 mm bore and a 1/8" port. At 0.5 MPa it provides 157 N of push force and 131.9 N of pull force. At 0.7 MPa, push increases to 219.8 N and pull to 184.7 N. The theoretical maximum force is 32 kgf at 1.0 MPa.
No, this specific SKU does not include an internal magnet, so it cannot accept CMSG, DMSG, or EMSG switches. You must select the -S magnet variant for position sensing. The stainless-steel build resists mild corrosion, and the adjustable air cushion at both ends only decelerates the piston near the stroke end; it does not lock or hold the load.
