Airtac MIC Cushioned Mini Cylinder MIC20X40SCA
The AirTAC Airtac MIC Cushioned Mini Cylinder MIC20X40SCA is a genuine double acting + cushion round-body mini air cylinder with a Ø20mm bore and 40mm stroke, 1/8" air ports and a stainless-steel barrel and rod for mildly corrosive environments. Its ISO 6432 mounting interface makes it a compact drop-in for standard mini-cylinder fixtures.

About the Airtac MIC Cushioned Mini Cylinder MIC20X40SCA
Built for high-speed actuation, this round-body stainless steel mini cylinder uses a needle-set variable air cushion at both ends to decelerate the load smoothly, eliminating the harsh impact of a fixed bumper. The MIC20X40SCA features a 20 mm bore, a 40 mm stroke, an M8x1.25 male rod thread, and a 1/8" port. A CA rear pivot cover provides clevis mounting flexibility.
As a double-acting actuator, it generates 157 N of push force and 131.9 N of pull force at 0.5 MPa, peaking at a theoretical 32 kgf at 1.0 MPa. The stainless barrel and rod resist mild washdown corrosion. Because the code includes -S, a built-in piston magnet supports CMSG, DMSG, and EMSG position switches. It conforms to ISO 6432 mounting dimensions, dropping directly into standard mini brackets. For a safe working load, expect roughly 94 N, lifting about 8 kg vertically with a 2:1 margin.

Where the Airtac MIC Cushioned Mini Cylinder MIC20X40SCA Is Used
Package Diverting
Snaps small cartons across a sorting line at speed, relying on the 157 N push force and tuned air cushions to stop cleanly without battering the goods.
Film Sealing Press
Drives a lightweight sealing jaw on automated packaging equipment, where the stainless build handles incidental moisture and the cushion prevents jaw slam.
Small Part Ejection
Pushes molded components out of a fixture quickly; the 8 kg vertical lift capacity handles dense plastic parts while the cushion absorbs the ejection shock.
Is the Airtac MIC Cushioned Mini Cylinder MIC20X40SCA the Right Cylinder?
When sizing this 20 mm bore unit, stepping down is not an equivalent cushioned option; the smaller 16 mm bore in the MI series relies on a fixed rubber bumper rather than an adjustable air cushion. Stepping up to the 25 mm MIC bore raises the 0.5 MPa push force to 245.3 N if your load exceeds the 157 N delivered here. The adjustable cushion proves vital when driving heavier masses at high speeds, as the needle valve lets you tune the end-of-stroke deceleration to protect the mechanism and reduce noise.
This cylinder includes a CA pivot back cover for clevis mounting and a -S magnet for sensors. Note that the air cushion only slows the piston near the stroke end; it does not function as a brake. If the air supply drops, the piston will drift, so fit an external rod lock or pilot check valve to hold a suspended load safely.
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 MIC20X40SCA FAQ
This double-acting cylinder uses a 1/8" port and an 8 mm rod. 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.
Yes, the -S suffix means it has a built-in magnet for CMSG, DMSG, or EMSG switches. The adjustable air cushion only decelerates the piston near the stroke end to reduce shock; it is not a brake, so you need a pilot check valve to hold a load vertically.
