About the Airtac MIC Cushioned Mini Cylinder MIC20X45SU
Designed for high-speed actuation, this double-acting round-body mini cylinder uses a needle-set variable air cushion at both ends to decelerate the piston smoothly, cutting end-of-stroke shock and noise. The stainless-steel barrel and Ø8 mm piston rod provide reliable mild corrosion resistance, making it suitable for washdown or humid industrial environments.
Operating on a 1/8" port and an M8x1.25 male rod thread, the Ø20 mm bore generates 157 N of push force at 0.5 MPa. This yields a safe working load of roughly 94 N, or the ability to lift about 8 kg vertically with a 2:1 safety margin. The built-in -S piston magnet supports CMSG, DMSG, and EMSG position switches, while the U back cover provides a 90-degree mounting orientation.

Where the Airtac MIC Cushioned Mini Cylinder MIC20X45SU Is Used
Package Diverting
Pushes light cartons at high cycle rates on a sorting line, using the adjustable air cushion to stop the 45 mm stroke gently without jarring the mechanism.
Small Part Ejection
Ejects machined components from a fixture, leveraging the 157 N push force and stainless build to withstand mildly humid shop conditions.
Flap Folding
Folds cardboard flaps on an automated packing station where the U rear cover and ISO 6432 dimensions allow easy 90-degree mounting.
Is the Airtac MIC Cushioned Mini Cylinder MIC20X45SU the Right Cylinder?
When sizing this 45 mm stroke unit, consider the adjacent bores: the smaller Ø16 generates 100.5 N of push at 0.5 MPa, whereas stepping up to the Ø25 provides 245.3 N. Choose the Ø20 for compact tasks needing around 157 N of push. The adjustable air cushion is essential when cycling at high speeds or moving sensitive loads, as it absorbs kinetic energy without harsh impacts. It strictly decelerates the stroke end and does not function as a brake.
Because a standard pneumatic cylinder will drift and lose its position if air pressure drops, you must add an external rod lock or pilot-operated check valve for secure load holding. This model uses the ISO 6432 mounting interface for standard mini brackets, and the included -S magnet enables electronic or reed sensor tracking.
Quick checklist
- ✓ Required force at your working pressure

- ✓ 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 MIC20X45SU FAQ
This Ø20 mm bore cylinder features 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 force of 32 kgf at 1.0 MPa.
No, the adjustable air cushion only decelerates the piston near the stroke end and acts purely as a shock absorber, never a brake. If air pressure drops, the piston will drift, so an external rod lock or pilot check valve is required to hold a vertical load securely.
