About the Airtac MIC Cushioned Mini Cylinder MIC20X350SU
Handling mid-range linear tasks, this double-acting stainless steel round-body mini cylinder features needle-adjustable air cushions at both ends to absorb high-speed end-of-stroke shock. The Ø20 mm bore 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 corrosion-resistant barrel and rod suit washdown environments, while the U-style 90-degree rear cover simplifies port and mounting orientation.
For practical sizing, expect a safe working load around 94 N, which translates to lifting about 8 kg vertically with a 2:1 safety margin. The built-in -S piston magnet supports CMSG, DMSG, and EMSG switches for position sensing. Conforming to the ISO 6432 mounting interface for Ø16-Ø25 bores, it drops directly into standard mini-cylinder brackets and clevises.

Where the Airtac MIC Cushioned Mini Cylinder MIC20X350SU Is Used
Package Diverting
Routes light cartons at high speed on a sorting line, using the adjustable cushions to stop the 350 mm stroke smoothly without slamming the diverter arm.
Film Sealing Press
Drives a sealing jaw up and down repeatedly, relying on the 157 N push force and washdown-resistant stainless build to handle damp packaging areas.
Small Part Elevation
Lifts approximately 8 kg of totes vertically between conveyor tiers, using the ISO 6432 mounting brackets to integrate into existing conveyor frames.
Is the Airtac MIC Cushioned Mini Cylinder MIC20X350SU the Right Cylinder?
When sizing this 350 mm stroke unit, stepping down to a MIC16 bore drops the 0.5 MPa push force to 100.5 N, whereas moving up to a MIC25 bore raises it to 245.3 N. Choose this Ø20 model for loads near its 94 N safe working capacity where high travel speeds make the adjustable needle cushions essential for protecting the payload. The U back cover provides a 90-degree mount for tight layouts.
Remember that the air cushion only decelerates the piston near the stroke end; it does not function as a brake. If air pressure drops, the piston will drift, so fit an external rod lock or pilot-operated check valve to hold a suspended load safely. Position feedback requires the included -S magnet to pair with 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 MIC20X350SU 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.
The -S suffix indicates a built-in piston magnet for CMSG, DMSG, or EMSG sensors. The adjustable air cushions only decelerate the piston near stroke end and do not act as a brake; you must use an external rod lock or pilot check valve to hold a load on air loss.
