Airtac MIC Cushioned Mini Cylinder MIC20X135CA
The AirTAC Airtac MIC Cushioned Mini Cylinder MIC20X135CA is a genuine double acting + cushion round-body mini air cylinder with a Ø20mm bore and 135mm 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 MIC20X135CA
Handling 157 N of push force at 0.5 MPa, this stainless-steel round-body mini cylinder is built for double-acting operation. The 20 mm bore uses an M8x1.25 male rod thread and a 1/8 inch air port. Because the stroke is 135 mm, it sits well within the 500 mm standard limit. The defining feature of the MIC series is the adjustable air cushion at both ends. By turning a needle valve, you tune the end-of-stroke deceleration to absorb high-speed shock, protecting the load and cutting noise better than a fixed bumper.
The stainless barrel and piston rod resist mild corrosion and washdown environments. It drops into standard brackets using the ISO 6432 mini-cylinder mounting interface. For sizing, a safe working load is about 94 N, meaning it lifts roughly 8 kg vertically with a 2:1 safety margin. This specific SKU lacks the -S magnet, so it cannot accept CMSG, DMSG, or EMSG sensors. The rear CA pivot cover allows direct clevis mounting.

Where the Airtac MIC Cushioned Mini Cylinder MIC20X135CA Is Used
Package Diverting
Pushes light parcels at high speed on a sorting line, using the tuned air cushion to stop the 135 mm stroke gently without jarring the mechanism.
Small Parts Ejection
Ejects machined components from a fixture, relying on the 157 N push force and the CA pivot cover to absorb the shock of rapid ejection.
Flap Folding
Folds cardboard flaps on an automated packer where the stainless build resists dust and the adjustable cushion prevents crushing the board.
Is the Airtac MIC Cushioned Mini Cylinder MIC20X135CA the Right Cylinder?
If you need less force, the smaller MIC16 bore drops push force to 100.5 N at 0.5 MPa. Stepping up to the MIC25 bore raises push force to 245.3 N at 0.5 MPa. Choose this 20 mm bore when moving moderate loads at high cycling speeds where the adjustable needle cushion can be tuned to prevent end-of-stroke banging. The CA rear cover suits pivoting clevis mounts, while front options include LB foot, FA flange, SDB pivot, and TC trunnion brackets.
Remember that the air cushion only decelerates the piston near the stroke end; it is not a brake. If air pressure drops, the piston drifts and cannot hold position. To lock a load vertically, add an external rod lock or a pilot-operated check valve. Because this exact model lacks the -S suffix, it has no magnet and cannot mount position sensors.
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 MIC20X135CA FAQ
At 0.5 MPa it pushes 157 N and pulls 131.9 N. At 0.7 MPa it pushes 219.8 N and pulls 184.7 N. The theoretical maximum force is 32 kgf at 1.0 MPa. It uses a 1/8 inch air port and an M8x1.25 male rod thread.
No, this specific SKU lacks the internal magnet, so it cannot accept CMSG, DMSG, or EMSG switches. You would need the -S variant for sensing. The stainless round body includes a CA rear pivot cover and adjustable air cushions at both ends.
