Airtac MIC Cushioned Mini Cylinder MIC20X30SUTC
The AirTAC Airtac MIC Cushioned Mini Cylinder MIC20X30SUTC is a genuine double acting + cushion round-body mini air cylinder with a Ø20mm bore and 30mm 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 MIC20X30SUTC
Designed for high-speed actuation, this double-acting stainless steel round-body mini cylinder uses a variable air cushion at both ends to decelerate the load smoothly. You can dial in the needle valve to absorb end-of-stroke shock, protecting your machinery and cutting noise far better than a fixed rubber bumper. The Ø20 mm bore delivers 157 N of push force at 0.5 MPa, making it a solid fit for moderate-duty positioning tasks.
Built with a corrosion-resistant stainless barrel and rod, it handles light washdown environments with ease. It conforms to the ISO 6432 mounting interface for Ø20, so it drops directly into standard mini-cylinder brackets and clevises. The -S suffix means a piston magnet is installed, allowing you to mount CMSG, DMSG or EMSG sensors for position detection. With a 1/8" port and an M8x1.25 male rod thread, it lifts about 8 kg vertically with a 2:1 safety margin.

Where the Airtac MIC Cushioned Mini Cylinder MIC20X30SUTC Is Used
Package Diverting
Uses the 157 N push force at 0.5 MPa to push small cartons off a high-speed belt, relying on the dual air cushions to stop the 30 mm stroke without slamming.
Small Part Ejection
Ejects molded components from a press, where the stainless build resists shop coolant and the adjustable needle damps the rapid return impact.
Light Assembly Press
Brings a sub-8 kg tool head down onto a fixture, using the TC trunnion to pivot and the U rear cover to orient the 1/8" air lines cleanly.
Is the Airtac MIC Cushioned Mini Cylinder MIC20X30SUTC the Right Cylinder?
If you need less force, stepping down to the Ø16 bore drops the 0.5 MPa push force to 100.5 N, whereas moving up to the Ø25 bore raises it to 245.3 N for heavier payloads. The adjustable cushion matters most when driving this cylinder near its 800 mm/s speed limit or moving a substantial mass, preventing harsh impacts at the 30 mm stroke ends. Remember that the air cushion only decelerates the piston; it does not act as a brake. If your application must hold a load vertically during air loss, add an external rod lock or pilot-operated check valve.
This specific SKU includes a U-style 90-degree rear cover and a TC trunnion mount, giving you pivot flexibility right out of the box. Because it carries the -S magnet, you can fit reed or electronic switches directly into the slot. If you ever need a non-magnetic variant, a SKU without the S cannot take a sensor.
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 MIC20X30SUTC FAQ
This double-acting cylinder has a 20 mm bore and a 1/8" port. It generates 157 N of push and 131.9 N of pull at 0.5 MPa, or 219.8 N of push and 184.7 N of pull at 0.7 MPa. The theoretical maximum force is 32 kgf at 1.0 MPa.
Yes, the -S suffix indicates a built-in magnet for CMSG, DMSG or EMSG switches. The cylinder features a variable air cushion at both ends; you adjust a needle valve to decelerate the piston near stroke end, reducing shock. It is a deceleration device, not a locking brake.
