Airtac MIC Cushioned Mini Cylinder MIC20X65SU
The AirTAC Airtac MIC Cushioned Mini Cylinder MIC20X65SU is a genuine double acting + cushion round-body mini air cylinder with a Ø20mm bore and 65mm 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 MIC20X65SU
Dial in end-of-stroke deceleration with the AirTAC MIC20X65SU, a double-acting round-body mini cylinder built with a stainless-steel barrel and rod for mild washdown resistance. The integrated -S piston magnet allows direct mounting of CMSG, DMSG, or EMSG switches for position sensing, while the U back cover provides a 90-degree port and mounting orientation. A 1/8" port feeds the Ø8 mm piston rod, yielding 157 N of push force and 131.9 N of pull force at 0.5 MPa.
The defining feature is the adjustable air cushion at both ends: a needle valve lets you tune the exhaust bleed to absorb kinetic energy at high speeds, protecting the load and reducing noise better than a fixed bumper. This translates to a safe working load of roughly 94 N, capable of lifting about 8 kg vertically with a 2:1 safety margin. It conforms to the ISO 6432 mounting interface for standard mini-cylinder brackets.

Where the Airtac MIC Cushioned Mini Cylinder MIC20X65SU Is Used
Light Package Diverting
Pushes small cartons at high speed across a transfer belt. The needle-set cushion prevents the 157 N stroke end from slamming, protecting lightweight packaging from impact damage.
Small Parts Ejection
Ejects molded plastic components from a tool. The stainless build handles occasional mist cooling, while the tuned deceleration stops the Ø8 mm rod smoothly without bouncing the part.
Vertical Lift Stops
Raises a 4 kg tote to a gravity roller line. The 2:1 safety margin handles the load easily, and the -S magnet tracks the exact raise position via a DMSG sensor.
Is the Airtac MIC Cushioned Mini Cylinder MIC20X65SU the Right Cylinder?
When sizing this 20 mm bore, compare it directly against adjacent models. If you need less force, dropping to an MIC16 lowers the push output to 100.5 N at 0.5 MPa; stepping up to an MIC25 raises it to 245.3 N. The 65 mm stroke sits well within the 500 mm standard limit. The adjustable cushion is most valuable when cycling at high speeds or moving heavier masses, allowing you to fine-tune the deceleration curve.
Remember that the air cushion only decelerates the piston near the stroke end; it does not function as a brake. If the air supply drops, the piston will drift, so install an external rod lock or pilot-operated check valve to hold a suspended load. For mounting flexibility, pair the U back cover with LB foot, FA flange, SDB pivot, or TC trunnion hardware.
Quick checklist

- ✓ 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 MIC20X65SU FAQ
This 20 mm bore cylinder features 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 and will not hold a load on air loss. For position sensing, the -S option includes a built-in magnet compatible with CMSG, DMSG, and EMSG switches.
