Airtac MIC Cushioned Mini Cylinder MIC20X45CA
The AirTAC Airtac MIC Cushioned Mini Cylinder MIC20X45CA is a genuine double acting + cushion round-body mini air cylinder with a Ø20mm bore and 45mm 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 MIC20X45CA
Damping high-speed strokes cleanly, the AirTAC MIC20X45CA uses a needle-set variable air cushion at both ends to absorb shock and reduce noise. This double-acting round-body mini cylinder features a stainless-steel barrel and rod for mild washdown resistance, conforming to the ISO 6432 mounting interface for standard bracket interchange. It pushes with 157 N and pulls with 131.9 N at 0.5 MPa, lifting about 8 kg vertically with a 2:1 safety margin. The 1/8" port and M8x1.25 male rod thread handle a 45 mm stroke, while the CA rear pivot cover simplifies clevis mounting.
Because this specific SKU lacks the -S magnet option, it cannot accept CMSG, DMSG, or EMSG sensors for position detection. The adjustable cushion only decelerates the load near the stroke end; it does not function as a brake. For vertical or suspended loads that must hold position on air loss, fit an external rod lock or pilot-operated check valve.

Where the Airtac MIC Cushioned Mini Cylinder MIC20X45CA Is Used
Light Part Ejection
Pushes small molded components out of a fixture using 157 N of force, relying on the adjustable cushion to prevent bouncing at 45 mm stroke end.
Package Diverting
Actuates a routing flap on a packaging line where the stainless build resists occasional washdown and the cushion softens high-speed stops.
Small Press Tending
Moves lightweight trays into a press area, using the CA pivot mount to accommodate slight angular misalignment during the transfer.
Is the Airtac MIC Cushioned Mini Cylinder MIC20X45CA the Right Cylinder?
If you need less force, dropping down to the Ø16 bore yields 100.5 N of push at 0.5 MPa, whereas stepping up to the Ø25 bore provides 245.3 N. The Ø20 bore is ideal for moderate loads moving at high speeds where the adjustable air cushion prevents end-of-stroke banging. Choose the -S magnet variant if your application requires CMSG, DMSG, or EMSG switches, as this base SKU cannot support sensing. Beyond the CA clevis cover, you can adapt the mounting using LB foot brackets, FA flanges, SDB pivot blocks, or TC trunnions.
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 MIC20X45CA FAQ
This double-acting cylinder pushes with 157 N and pulls with 131.9 N at 0.5 MPa. At 0.7 MPa, push is 219.8 N and pull is 184.7 N. The theoretical maximum force is 32 kgf at 1.0 MPa. It features a 1/8" port and an M8x1.25 male rod thread.
No, this specific SKU does not include a magnet, so it cannot accept CMSG, DMSG, or EMSG switches. You would need the -S variant for position sensing. The variable air cushion at both ends only serves to decelerate the load near the stroke end and is not a locking brake.
