Airtac MIC Cushioned Mini Cylinder MIC20X300U
The AirTAC Airtac MIC Cushioned Mini Cylinder MIC20X300U is a genuine double acting + cushion round-body mini air cylinder with a Ø20mm bore and 300mm 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 MIC20X300U
Delivering 157 N of push force at 0.5 MPa, this double-acting stainless steel round-body mini cylinder handles a 300 mm stroke with a 1/8" port. The defining feature of the MIC series is the adjustable air cushion at both ends. By turning a needle valve, you tune the deceleration to absorb end-of-stroke shock at high speeds, protecting the load and reducing noise compared to a fixed bumper.
Built with a stainless-steel barrel and rod, it resists mild corrosion and washdown environments. It uses the standard ISO 6432 mounting interface for easy bracket integration. For sizing, a safe working load is roughly 94 N, or it lifts about 8 kg vertically with a 2:1 margin. This specific SKU lacks the -S magnet, so it cannot accept CMSG, DMSG, or EMSG sensors. The U back cover provides a 90-degree mounting orientation.

Where the Airtac MIC Cushioned Mini Cylinder MIC20X300U Is Used
Package Diverting
Pushes light cartons at high cycle rates on a sorting line. The adjustable air cushion absorbs the end-of-stroke impact, preventing the 157 N push force from jarring the conveyor frame.
Small Part Ejection
Ejects machined components from a fixture. The stainless build resists cutting fluid splash, while the U back cover mounts cleanly at a 90-degree angle to the machine bed.
Light Gate Actuation
Opens and closes light access doors. Operating at 0.5 MPa provides ample force, and the tuned cushion ensures the 300 mm stroke completes quietly without slamming.
Is the Airtac MIC Cushioned Mini Cylinder MIC20X300U the Right Cylinder?
When sizing this 20 mm bore, stepping down to an MIC16X300 drops the 0.5 MPa push force to 100.5 N, while stepping up to an MIC25X300 raises it to 245.3 N. The adjustable cushion matters most when cycling at high speeds or moving heavier masses, where impact shock would otherwise damage the assembly. Note that the air cushion only decelerates the piston near the stroke end; it does not act as a brake. If the application must hold a load vertically during air loss, add an external rod lock or pilot-operated check valve. Mounting options include LB foot, FA flange, SDB pivot, and TC trunnion, but remember this non-magnet version cannot support position sensing.
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 MIC20X300U FAQ
This 20 mm bore cylinder features a 1/8" port and an M8x1.25 male rod thread. At 0.5 MPa it pushes with 157 N and pulls with 131.9 N. At 0.7 MPa it pushes with 219.8 N and pulls with 184.7 N. The theoretical maximum force is 32 kgf at 1.0 MPa.
This specific SKU does not have a magnet, so it cannot accept CMSG, DMSG, or EMSG switches; you need the -S variant for sensing. The adjustable air cushion at both ends uses a needle to regulate exhaust flow, decelerating the piston smoothly at high speeds. It is not a locking brake.
