About the Airtac MIC Cushioned Mini Cylinder MIC20X45SCA
Engineered for rapid actuation, this double-acting stainless steel round-body mini cylinder uses a needle-set variable air cushion at both ends to decelerate loads smoothly, minimizing end-of-stroke impact and noise compared to fixed bumper designs. The Ø20 mm bore develops 157 N of push force and 131.9 N of pull force at 0.5 MPa, while the corrosion-resistant barrel and rod withstand mild washdown environments. It features a 1/8" port, an M8x1.25 male rod thread, and a built-in piston magnet for position sensing.
Dropping into standard ISO 6432 mini-cylinder mounting interfaces, the rear CA clevis simplifies pivot integration. With a practical safe working load of roughly 94 N, it can vertically lift about 8 kg with a 2:1 safety margin. The integrated magnet enables CMSG, DMSG, or EMSG switches to track position, operating reliably at speeds from 30 to 800 mm/s across a -20 to +70 C temperature range.

Where the Airtac MIC Cushioned Mini Cylinder MIC20X45SCA Is Used
Package Diverting
Swiftly routes small cartons on a conveyor line, utilizing the adjustable air cushion to halt the 45 mm stroke gently without jarring the mechanism.
Component Ejection
Pushes lightweight machined parts out of a fixture at high speed, relying on the 157 N thrust and stainless build to resist shop-floor splashing.
Bin Sorting
Actuates a small sorting flap for parts bins, where the CA clevis mount provides the necessary pivot action for the swinging gate.
Is the Airtac MIC Cushioned Mini Cylinder MIC20X45SCA the Right Cylinder?
When sizing this unit, consider the next bore down and up: the Ø16 variant yields 100.5 N push at 0.5 MPa, whereas the Ø25 steps up to 245.3 N. Select this Ø20 model when your application demands approximately 94 N of safe working force. The adjustable air cushion is essential for high-speed cycles carrying heavier masses, as it absorbs kinetic energy that would otherwise slam the piston. Remember that the cushion only decelerates the load near the stroke end; it does not function as a brake. If you need to prevent drift on air loss, install an external rod lock or pilot-operated check valve.
The -S magnet allows seamless mounting of CMSG, DMSG, or EMSG sensors without extra hardware. For structural mounting, the CA rear clevis pairs with standard pivot pins, and you can adapt the body using LB foot, FA flange, SDB pivot-block, or TC trunnion hardware to fit your frame.
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 MIC20X45SCA FAQ
This double-acting cylinder uses 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, or 219.8 N push and 184.7 N pull at 0.7 MPa. The theoretical maximum force is 32 kgf at 1.0 MPa.
No, the adjustable air cushion only decelerates the piston near the stroke end and is not a locking brake. The piston will drift on air loss. To hold a suspended load, you must add an external rod lock or pilot-operated check valve. The built-in -S magnet supports CMSG, DMSG, and EMSG sensors.
