Airtac MIC Cushioned Mini Cylinder MIC20X50SU
The AirTAC Airtac MIC Cushioned Mini Cylinder MIC20X50SU 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 MIC20X50SU
Dial in end-of-stroke deceleration with the AirTAC MIC20X50SU, a 20 mm bore double-acting mini cylinder built around a stainless steel round barrel and rod for mild washdown resistance. A needle-set variable air cushion at both ends absorbs high-speed shock, lowering noise and protecting the payload better than a fixed bumper. It uses the ISO 6432 mounting interface for standard brackets and features a U-style 90-degree rear cover.
Generating 157 N of push and 131.9 N of pull at 0.5 MPa, this unit handles a safe working load of roughly 94 N. That translates to lifting about 8 kg vertically with a 2:1 safety margin. The -S suffix adds a piston magnet for CMSG, DMSG or EMSG position switches, and the 1/8" port feeds an 8 mm rod with an M8x1.25 male thread.

Where the Airtac MIC Cushioned Mini Cylinder MIC20X50SU Is Used
Light Package Diverting
Pushes small cartons at high speed across a belt line, relying on the adjustable cushion to stop the 8 kg payload gently without bounce.
Small Component Ejection
Ejects light machined parts from a fixture using 157 N of push force, with the needle cushion absorbing the shock of rapid ejection.
Flap Folding Control
Folds cardboard flaps on a packaging line where the stainless build resists mild moisture and the cushion silences end-of-stroke thumps.
Is the Airtac MIC Cushioned Mini Cylinder MIC20X50SU the Right Cylinder?
If you need less force, the smaller 16 mm bore provides 100.5 N push at 0.5 MPa; stepping up to the 25 mm bore yields 245.3 N. Choose this 20 mm bore when moving light payloads at high cycle speeds where the adjustable cushion prevents harsh impacts. Because the cushion only decelerates near the stroke end and the cylinder drifts on air loss, add an external rod lock or pilot check valve if you must hold a vertical load safely.
Mounting options include LB foot, FA flange, SDB pivot and TC trunnion. The U-style 90-degree back cover suits specific spatial constraints, while the -S magnet enables electronic or reed sensor tracking.
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 MIC20X50SU FAQ
This 20 mm bore cylinder uses a 1/8" port and an 8 mm rod with an M8x1.25 male 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 max of 32 kgf at 1.0 MPa.
The variable air cushion at both ends uses a needle valve to decelerate the piston near stroke end, reducing shock at speeds up to 800 mm/s. The -S suffix means it has a built-in magnet for CMSG, DMSG or EMSG sensors, but the cushion is not a brake and will not hold the load on air loss.
