Airtac MIC Cushioned Mini Cylinder MIC20X450CM
The AirTAC Airtac MIC Cushioned Mini Cylinder MIC20X450CM is a genuine double acting + cushion round-body mini air cylinder with a Ø20mm bore and 450mm 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 MIC20X450CM
Delivering 157 N of push force at 0.5 MPa, this double-acting stainless steel round-body mini cylinder handles a 450 mm stroke with precision. The Ø20 mm bore features a 1/8" port and an M8x1.25 male rod thread. A CM round rear cover provides specific mounting orientation for compact installations.
Unlike standard bumper units, the MIC range integrates an adjustable air cushion at both ends. Turning the needle valve lets you tune the end-of-stroke deceleration, effectively absorbing high-speed shock and reducing noise. With a safe working load of roughly 94 N, it lifts about 8 kg vertically under a 2:1 safety margin. The riveted stainless barrel and rod resist mild corrosion, and because this SKU lacks the -S magnet, it cannot host CMSG, DMSG, or EMSG sensors.

Where the Airtac MIC Cushioned Mini Cylinder MIC20X450CM Is Used
Package Diverting
Uses the 450 mm stroke to push light parcels across transfer belts at high speed, relying on the adjustable cushion to prevent harsh slamming at full extension.
Light Part Ejection
Ejects molded plastic components from small fixtures, using the 157 N push force while the tuned air cushion protects delicate parts from impact damage.
Bin Sorting
Actuates small sorting gates in washdown-prone packing zones, where the stainless steel construction maintains operational integrity against mild moisture.
Is the Airtac MIC Cushioned Mini Cylinder MIC20X450CM the Right Cylinder?
When sizing this unit, consider the next bore up: the Ø32 MIC provides 402 N of push at 0.5 MPa for heavier loads, while the smaller Ø16 MI offers 100.5 N but relies on a fixed bumper rather than adjustable cushions. Choose this Ø20 model for high-speed cycles where tuning the end-of-stroke shock is critical. It conforms to the ISO 6432 mounting interface for standard mini-cylinder brackets.
Remember that the air cushion only decelerates the piston near the stroke end; it does not act as a lock or brake. If your application must hold a load vertically during air loss, add an external rod lock or pilot-operated check valve. To add position sensing, you must switch to the -S magnet variant, as this base SKU cannot accept a switch.
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 MIC20X450CM FAQ
This double-acting cylinder uses a 1/8" port and generates 157 N push / 131.9 N pull at 0.5 MPa, and 219.8 N push / 184.7 N pull at 0.7 MPa. The theoretical maximum force is 32 kgf at 1.0 MPa.
No, this specific SKU does not include a magnet. You must select the -S variant to use CMSG, DMSG, or EMSG sensors. The adjustable air cushion at both ends functions only to decelerate the load, not to hold it.
