About the Airtac MIC Cushioned Mini Cylinder MIC20X350U
Engineered for high-speed automation, the AirTAC MIC20X350U is a double-acting, round-body stainless steel mini cylinder featuring a 350 mm stroke and a 90-degree U rear cover. Its defining feature is the adjustable air cushion at both ends, allowing you to tune a needle valve to absorb end-of-stroke shock. This protects the load and significantly cuts noise compared to a standard bumper mini cylinder. The stainless barrel and rod resist mild corrosion and washdown environments.
Operating at 0.15 to 1.0 MPa, this Ø20 bore generates 157 N of push force and 131.9 N of pull force at 0.5 MPa. For practical sizing, it yields a safe working load of about 94 N, lifting roughly 8 kg vertically with a 2:1 safety margin. It uses a 1/8" port and an M8x1.25 male rod thread. Because this SKU lacks the -S magnet, it cannot accept CMSG, DMSG, or EMSG position sensors.

Where the Airtac MIC Cushioned Mini Cylinder MIC20X350U Is Used
Package Diverting
Pushes light cartons at high speed on a sorting line, using the adjustable cushion to stop the 350 mm stroke gently without jarring the conveyor frame.
Small Part Ejection
Ejects machined components from a fixture, leveraging the 157 N push force while the stainless build resists cutting fluid mist.
Bin Gate Actuation
Opens and closes light hopper gates for dry bulk materials, where the 90-degree U cover and washdown-ready stainless rod suit dusty or damp settings.
Is the Airtac MIC Cushioned Mini Cylinder MIC20X350U the Right Cylinder?
When sizing this 350 mm stroke unit, consider the adjacent bores in the MIC range. Dropping down to a Ø16 bore reduces the push force to 100.5 N at 0.5 MPa, while stepping up to a Ø25 bore increases it to 245.3 N. The adjustable cushion matters most when driving heavier loads at high speeds up to 800 mm/s, where deceleration tuning prevents impact damage. Note that the cushion only decelerates near the stroke end; it is not a brake. Because a plain cylinder drifts on air loss, use an external rod lock or pilot check valve if you must hold a vertical load.
The U-style back cover provides a 90-degree mounting orientation for compact spatial constraints. This Ø20 size uses the ISO 6432 mini-cylinder mounting interface, dropping directly into standard mini brackets and clevises. Since this specific configuration has no magnet, you cannot mount reed or solid-state switches; choose the -S variant if your application requires CMSG, DMSG, or EMSG sensors.
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 MIC20X350U FAQ
This double-acting cylinder has a 1/8" 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 of 32 kgf at 1.0 MPa.
No, this specific SKU does not include a magnet. You must select the -S version of the MIC to use CMSG, DMSG, or EMSG sensors. The adjustable air cushion at both ends only serves to decelerate the piston and is not a locking mechanism.
