Airtac MIC Cushioned Mini Cylinder MIC20X230SU
The AirTAC Airtac MIC Cushioned Mini Cylinder MIC20X230SU is a genuine double acting + cushion round-body mini air cylinder with a Ø20mm bore and 230mm 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 MIC20X230SU
Generating 157 N of push force at 0.5 MPa, this double-acting stainless steel round-body mini cylinder handles a 230 mm stroke with precision. The built-in piston magnet (-S) directly supports CMSG, DMSG and EMSG switches for position sensing, while the U back cover provides a 90-degree mounting and port orientation. It features an M8x1.25 male rod thread and a 1/8" air port.
A defining feature is the adjustable air cushion at both ends, allowing you to needle-set the deceleration to absorb end-of-stroke shock at high speeds. This protects the load and cuts noise compared to a fixed bumper. For practical sizing, expect a safe working load of about 94 N, which means it lifts roughly 8 kg vertically with a 2:1 safety margin.

Where the Airtac MIC Cushioned Mini Cylinder MIC20X230SU Is Used
Package Diverting
Uses the 157 N push force to deflect light cartons on a high-speed sorting line, relying on the adjustable cushion to prevent harsh end-of-stroke impacts.
Pallet Gate Control
Actuates a lightweight safety gate on a pallet wrapper, where the 230 mm stroke and 90-degree U back cover fit tight spatial constraints.
Film Roll Tensioning
Maintains precise tension on a packaging web, using the -S magnet and DMSG sensor to confirm position and the needle cushion to stop smoothly.
Is the Airtac MIC Cushioned Mini Cylinder MIC20X230SU the Right Cylinder?
When sizing this 20 mm bore unit, stepping down is not an option if you need the adjustable cushion, as the smaller 16 mm bore MI variant only offers a fixed bumper. If your application requires more force, the next size up is the MIC25, which provides 245 N of push at 0.5 MPa. The variable cushioning here is essential when cycling at high speeds or moving heavier masses to prevent impact damage.
Note that the air cushion only decelerates the piston near the stroke end; it does not act as a brake. If the air supply drops, the piston will drift, so fit an external rod lock or pilot check valve to hold a load safely. For mounting, you can use standard ISO 6432 brackets and clevises, or opt for LB foot, FA flange, SDB pivot or TC trunnion accessories.
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 MIC20X230SU FAQ
This 20 mm bore cylinder has a 1/8" air port and an M8x1.25 male rod thread. It generates 157 N push and 131.9 N pull at 0.5 MPa, 219.8 N push and 184.7 N pull at 0.7 MPa, with a theoretical maximum force of 32 kgf at 1.0 MPa.
No, the adjustable air cushion only decelerates the piston near the end of the stroke to reduce shock; it is not a brake or lock. If air pressure drops, the piston will drift, so you must use an external rod lock or pilot check valve to hold a load securely.
