Airtac MIC Cushioned Mini Cylinder MIC20X50SCM
The AirTAC Airtac MIC Cushioned Mini Cylinder MIC20X50SCM is a genuine double acting + cushion round-body mini air cylinder with a Ø20mm bore and 50mm 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 MIC20X50SCM
Tame high-speed end-of-stroke shock with the AirTAC MIC20X50SCM, a 20 mm bore double-acting mini cylinder built around a stainless-steel round barrel and rod. Instead of a fixed bumper, it uses a needle-set adjustable air cushion at both ends to decelerate the load smoothly, protecting your mechanism and lowering shop noise. The riveted construction shrugs off mild corrosion and washdown, while the 1/8" port and M8x1.25 male rod thread keep standard mini-cylinder plumbing and mounting simple.
In this force class the cylinder delivers 157 N of push and 131.9 N of pull at 0.5 MPa, peaking at a theoretical 32 kgf at 1.0 MPa. For practical sizing that translates to a safe working load of about 94 N, or roughly 8 kg of vertical lift with a 2:1 margin. The -S suffix means a piston magnet is fitted for CMSG, DMSG or EMSG position switches, and the CM rear cover provides a clean round-end port orientation for tight assemblies.

Where the Airtac MIC Cushioned Mini Cylinder MIC20X50SCM Is Used
Light Package Diverting
Snaps small cartons off a belt at high cycle rates. The adjustable cushion absorbs the 157 N push impact, preventing bounce as the diverter reaches end of stroke.
Small Parts Clamping
Holds aluminium or plastic workpieces for machining. The stainless build resists cutting fluid mist, while the 131.9 N pull at 0.5 MPa secures the part without crushing it.
Flap Folding
Folds cardboard flaps on a packaging line. The needle-set cushion ensures the flap is tucked firmly but quietly, reducing wear on the cardboard and the cylinder itself.
Is the Airtac MIC Cushioned Mini Cylinder MIC20X50SCM the Right Cylinder?
When sizing this 20 mm bore, step down to an MIC16 if your load is lighter (100.5 N push at 0.5 MPa) or move up to an MIC25 if you need more thrust (245.3 N push). The adjustable cushion matters most when you are running near the 800 mm/s speed limit or moving a heavy payload, letting you dial in deceleration without hammering the end caps. Because the CM back cover and ISO 6432 mounting dimensions are standard, it drops directly into common mini-cylinder brackets and clevises.
Remember that the air cushion only slows the piston near the end of stroke; it is not a brake. If air pressure drops or the valve is centred, the rod will drift and the load can fall. For vertical or suspended loads that must hold position on air loss, fit an external rod lock or a pilot-operated check valve.
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 MIC20X50SCM FAQ
This 20 mm bore cylinder has a 1/8" port and an M8x1.25 male rod thread. At 0.5 MPa it pushes with 157 N and pulls with 131.9 N. At 0.7 MPa the push is 219.8 N and the pull is 184.7 N. The theoretical maximum force is 32 kgf at 1.0 MPa.
Yes, the -S suffix indicates a built-in piston magnet, allowing you to mount CMSG, DMSG or EMSG reed or electronic switches directly to the barrel. The adjustable air cushion at both ends uses a needle valve to trap exhaust air, decelerating the piston smoothly at high speeds. It only slows the load near stroke end and does not act as a lock.
