About the Airtac MIC Cushioned Mini Cylinder MIC20X40SU
Designed for rapid actuation, this stainless-steel round-body mini cylinder uses a needle-set variable air cushion at both ends to absorb end-of-stroke shock. As the double-acting adjustable-cushion evolution of the MI series, it significantly reduces impact noise compared to fixed bumper models. The Ø20 bore uses an M8x1.25 male rod thread and a 1/8" port.
Delivering 157 N of push force and 131.9 N of pull force at 0.5 MPa, it handles a safe working load of roughly 94 N. This equates to lifting about 8 kg vertically with a 2:1 safety margin. The built-in piston magnet (-S) supports CMSG, DMSG, and EMSG switches, while the U-type back cover provides a 90-degree port orientation for tight layouts. It conforms to the ISO 6432 mounting interface for standard mini-cylinder brackets.

Where the Airtac MIC Cushioned Mini Cylinder MIC20X40SU Is Used
Package Diverting
Ideal for pushing small cartons at high speed on a conveyor. The adjustable air cushion stops the 8 kg load smoothly without slamming, while the 1/8" port keeps airflow responsive.
Small Part Clamping
Clamps lightweight aluminum fixtures during machining. The 94 N safe working force holds parts securely, and the stainless build resists cutting fluid mist.
Compact Gate Actuation
Drives a 40 mm stroke sorting gate in tight spaces. The 90-degree U cover allows hose routing close to the frame, and CMSG sensors track the gate position.
Is the Airtac MIC Cushioned Mini Cylinder MIC20X40SU the Right Cylinder?
For lighter duties, the Ø16 bore provides 100.5 N push at 0.5 MPa, whereas stepping up to the Ø25 bore yields 245.3 N. Choose this Ø20 model when you need 157 N of push force combined with high-speed cycling where the adjustable air cushion prevents load damage. The cushion only decelerates near the stroke end and does not act as a brake.
Because a standard cylinder drifts on air loss, hold suspended loads with an external rod lock or pilot check valve. You can mount this unit using LB foot, FA flange, SDB pivot, or TC trunnion hardware. The -S magnet enables position sensing, and the U-type rear cover simplifies plumbing in confined spaces.
Quick checklist
- ✓ Required force at your working pressure

- ✓ 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 MIC20X40SU FAQ
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 Ø20 bore model features a 1/8" air port and an Ø8 mm piston rod.
Yes, the -S suffix indicates a built-in magnet compatible with CMSG, DMSG, and EMSG switches. The variable air cushion at both ends uses a needle valve to decelerate the piston near stroke end to reduce shock. It is a deceleration feature only, not a locking brake.
