The AirTAC Airtac MIC Cushioned Mini Cylinder MIC20X85SU is a genuine double acting + cushion round-body mini air cylinder with a Ø20mm bore and 85mm 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.
Tame high-speed end-of-stroke shock with the AirTAC MIC20X85SU, a 20 mm bore double-acting mini cylinder built with a stainless-steel round barrel and piston rod for mild washdown resistance. A variable air cushion at both ends lets you needle-set the deceleration to protect payloads, dropping directly into standard ISO 6432 mini-cylinder mounting interfaces. The U rear cover provides a 90-degree port and mounting orientation for tight spatial layouts.
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, lifting about 8 kg vertically with a 2:1 margin. The 1/8" port feeds the 8 mm piston rod, and the built-in -S magnet supports CMSG, DMSG, and EMSG position switches.

MI-family variants: MI / MIC (double acting ±cushion), MSI / MTI (single acting push / pull), MID / MICD (double rod ±cushion), MIJ / MICJ (adjustable stroke ±cushion). Back covers CA / U / R / CM. Mounting LB / FA / SDB / TC.
Pushes small cartons at high cycle rates on a packaging line, using the adjustable cushion to silently absorb the 8 kg dynamic load at stroke end.
Ejects molded components from a press quickly, relying on the needle-set air cushion to prevent impact damage to the 8 mm rod and tooling.
Opens and closes light material hoppers where the stainless barrel resists mild dust corrosion and the U cover clears the 90-degree porting.
If you need less force, the smaller 16 mm bore yields 100.5 N push at 0.5 MPa but lacks the adjustable cushion; stepping up to the 25 mm bore provides 245.3 N push for heavier payloads. Choose this 20 mm bore with its 85 mm stroke when moving masses at high speeds where a fixed bumper would transmit damaging shock. Because the air cushion only decelerates near the stroke end, it will not hold a load if air pressure drops—the piston drifts, so add an external rod lock or pilot check valve for suspended loads.
Secure the body using LB foot, FA flange, SDB pivot, or TC trunnion mounts. The included -S magnet enables electronic or reed sensor tracking, whereas a non-magnet SKU cannot take a switch.
Quick checklist
This 20 mm bore 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 of 32 kgf at 1.0 MPa.
Yes, the -S magnet allows CMSG, DMSG, and EMSG switches. The adjustable air cushion only decelerates the piston near the stroke end to reduce shock; it is not a brake and will not hold a load on air loss.
