About the Airtac MIC Cushioned Mini Cylinder MIC20X90SU
Soak up high-speed end-of-stroke shock with the AirTAC MIC20X90SU, a stainless round-body mini cylinder featuring needle-set air cushions at both ends. This double-acting actuator uses a 1/8" port and an M8x1.25 male rod thread, pushing with 157 N and pulling with 131.9 N at 0.5 MPa. Its riveted stainless barrel and rod resist mild washdown corrosion, and the built-in -S piston magnet supports CMSG, DMSG, or EMSG position switches.
Designed for a 90 mm stroke, this Ø20 bore unit drops directly into standard ISO 6432 mini-cylinder brackets and clevises. The adjustable cushioning lets you dial in deceleration to protect payloads, delivering a safe working load of roughly 94 N. It will lift about 8 kg vertically with a 2:1 safety margin, while the U-style rear cover provides a 90-degree mounting orientation for compact layouts.

Where the Airtac MIC Cushioned Mini Cylinder MIC20X90SU Is Used
Package Diverting
Shift small cartons at high speed on a sorting line; the adjustable cushion absorbs the stroke impact to prevent jarring the conveyor framework.
Light Assembly Press
Apply a steady 157 N clamping force for seating small bearings, using the 90 mm stroke to clear the workpiece on retraction.
Vertical Lift Gate
Hoist an 8 kg access flap with a 2:1 safety margin, relying on the stainless build to endure humid warehouse environments.
Is the Airtac MIC Cushioned Mini Cylinder MIC20X90SU the Right Cylinder?
When sizing this 90 mm stroke actuator, note the Ø20 bore yields 157 N push at 0.5 MPa. If you need less force, the smaller Ø16 bore offers 100.5 N but lacks the adjustable cushion, coming only as an MI bumper version. For heavier payloads, stepping up to the Ø25 bore increases thrust to 245.3 N. Choose this MIC model specifically when cycle speeds are high enough that end-of-stroke shock would damage a standard bumper cylinder.
The needle cushions only decelerate the piston near the end of travel; they do not lock or hold the load. If air pressure drops, the rod will drift, so fit an external rod lock or pilot-operated check valve for suspended loads. The -S magnet enables CMSG, DMSG, and EMSG sensors, and you can mount it via LB foot, FA flange, SDB pivot, or TC trunnion alongside the standard U back cover.
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 MIC20X90SU FAQ
This double-acting cylinder uses 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 the push is 219.8 N and the pull is 184.7 N. The theoretical maximum force is 32 kgf at 1.0 MPa.
The MIC20X90SU features a variable air cushion at both ends that you tune with a needle valve to decelerate the piston smoothly at high speeds. The included -S piston magnet allows you to mount CMSG, DMSG, or EMSG electronic or reed switches for position sensing.
