Airtac MIC Cushioned Mini Cylinder MIC20X240SU
The AirTAC Airtac MIC Cushioned Mini Cylinder MIC20X240SU is a genuine double acting + cushion round-body mini air cylinder with a Ø20mm bore and 240mm 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 MIC20X240SU
Handling moderate thrust with precision, this double-acting stainless steel round-body mini cylinder features an adjustable air cushion at both ends. Tuning the cushion needle lets you soak up high-speed end-of-stroke shock, protecting payloads far better than a fixed bumper. The Ø20 mm bore pushes 157 N and pulls 131.9 N at 0.5 MPa, while the stainless barrel and rod resist mild washdown corrosion. Because it carries the -S suffix, a built-in piston magnet supports CMSG, DMSG, or EMSG position switches.
With a 240 mm stroke and a U-type 90-degree rear cover, it drops easily into ISO 6432 standard mini-cylinder brackets and clevises. Operating speed spans 30-800 mm/s, and the 1/8" port feeds air efficiently. For sizing context, its safe working load is roughly 94 N, meaning it lifts about 8 kg vertically with a 2:1 safety margin.

Where the Airtac MIC Cushioned Mini Cylinder MIC20X240SU Is Used
Package Diverting
Routes light cartons at high cycle rates where the adjustable cushion prevents harsh slams that could scuff packaging.
Small Part Ejection
Pushes molded components out of a press area, using the 157 N thrust to clear the die before the next cycle.
Vertical Lift Gates
Raises an 8 kg access flap with a 2:1 safety margin, relying on the U cover for a clean 90-degree pivot mount.
Is the Airtac MIC Cushioned Mini Cylinder MIC20X240SU the Right Cylinder?
If your payload is lighter, the smaller Ø16 bore (MI-only bumper version) lacks the adjustable cushion, so this MIC20 is the entry point for tuned deceleration. Stepping up to the Ø25 bore raises push force to 245.3 N at 0.5 MPa for heavier guides. The cushion matters most when cycling at high speed or moving a mass that would otherwise slam into the endcap.
Remember that the air cushion only decelerates the piston near stroke end; it does not lock or hold the load. If power drops, the rod drifts, so fit an external rod lock or pilot check valve for vertical safety. Mounting options include LB foot, FA flange, SDB pivot, and TC trunnion, and the -S magnet enables solid sensor feedback.
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 MIC20X240SU FAQ
This double-acting cylinder uses a 1/8" port and an M8x1.25 male rod thread. 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.
Yes, the -S suffix means it has a built-in magnet for CMSG, DMSG, or EMSG switches. The adjustable air cushion at both ends only decelerates the piston near stroke end to reduce shock; it is not a brake. The rod will drift on air loss, so use a pilot check valve or rod lock to hold a load.
