Airtac MIC Cushioned Mini Cylinder MIC20X450SCM
The AirTAC Airtac MIC Cushioned Mini Cylinder MIC20X450SCM is a genuine double acting + cushion round-body mini air cylinder with a Ø20mm bore and 450mm 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 MIC20X450SCM
Dial in end-of-stroke deceleration on long 450 mm moves with the AirTAC MIC20X450SCM. This double-acting stainless steel round-body mini cylinder relies on a needle-set variable air cushion at both ends to soak up high-speed shock, protecting your payload far better than a fixed bumper. The Ø20 mm bore conforms to the ISO 6432 mounting interface, dropping directly into standard mini brackets and clevises.
The stainless barrel and Ø8 mm rod shrug off mild washdown corrosion, while the built-in piston magnet (-S) enables CMSG, DMSG, and EMSG position sensing. Operating at 0.5 MPa, it generates 157 N of push force and 131.9 N of pull. That translates to a safe working load of about 94 N, or roughly 8 kg of vertical lift with a 2:1 safety margin. Air connects via a 1/8" port, and the CM round rear cover keeps the footprint compact.

Where the Airtac MIC Cushioned Mini Cylinder MIC20X450SCM Is Used
Package Diverting
Use the 157 N push force and adjustable cushions to smoothly divert small totes across a 450 mm stroke without jarring the contents at high speed.
Light Assembly Press
Apply a consistent 8 kg vertical press force for seating small bearings, relying on the needle-set cushion to protect delicate tooling at stroke end.
Pallet Tagging
Extend 450 mm to apply labels in tight pallet cells; the stainless build handles humid ambient air while the -S magnet tracks position.
Is the Airtac MIC Cushioned Mini Cylinder MIC20X450SCM the Right Cylinder?
If you need less push, stepping down to the Ø16 bore drops the 0.5 MPa push force to 100.5 N. If your payload exceeds the 94 N safe working load here, the Ø25 bore jumps to 245.3 N. The adjustable cushion matters most when cycling at high speed across the 450 mm stroke or moving heavy masses, as it prevents harsh end-of-stroke slamming. Remember that the cushion only decelerates the piston; it does not act as a brake. If you must prevent drift on air loss, add an external rod lock or pilot check valve. This CM cover unit includes the -S magnet for sensors, and you can mount it using LB foot, FA flange, SDB pivot, or TC trunnion hardware.
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 MIC20X450SCM FAQ
At 0.5 MPa it pushes with 157 N and pulls with 131.9 N. At 0.7 MPa it pushes 219.8 N and pulls 184.7 N. The theoretical maximum force is 32 kgf at 1.0 MPa. This Ø20 bore uses a 1/8" air port and a M8x1.25 male rod thread.
No. The adjustable air cushion only decelerates the piston near the end of its 450 mm stroke; it is not a lock or brake. If power fails, the rod will drift. Use an external rod lock or pilot-operated check valve for load holding.
