The AirTAC Airtac MIC Cushioned Mini Cylinder MIC20X80SU is a genuine double acting + cushion round-body mini air cylinder with a Ø20mm bore and 80mm 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.
Dial in end-of-stroke deceleration with the AirTAC MIC20X80SU, a 20 mm bore, 80 mm stroke double-acting mini cylinder built around a stainless-steel round barrel and rod. A needle-set variable air cushion at both ends absorbs high-speed shock, protecting your payload far better than a fixed rubber bumper. The riveted construction shrugs off mild corrosion and washdown environments, while the 1/8" port feeds an 8 mm piston rod to deliver 157 N of push force at 0.5 MPa.
This unit conforms to the ISO 6432 mounting interface, dropping directly into standard mini-cylinder brackets and clevises. The built-in -S piston magnet enables position sensing with CMSG, DMSG, or EMSG switches. For sizing, its safe working load is roughly 94 N (60 percent of the 0.5 MPa push figure), meaning it lifts about 8 kg vertically with a 2:1 safety margin. A U-style 90-degree rear cover provides flexible port and mounting orientation.

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.
Uses the 157 N push force to deflect small cartons on a high-speed sorting line, relying on the adjustable air cushion to stop the 80 mm stroke smoothly without jarring the belt.
Actuates a clamping jaw in a packaging machine where the stainless barrel resists washdown chemicals and the needle-set cushion prevents crushing delicate film rolls at stroke end.
Pushes molded parts out of an automated press, using the -S magnet and a DMSG sensor to confirm ejection while the cushion absorbs the kinetic energy of the 8 kg payload.
If you need less force, stepping down is not an option within the MIC cushioned range; the smaller Ø16 bore is your only adjacent choice, pushing 100.5 N at 0.5 MPa. If your payload exceeds the 157 N push rating here, move up to the Ø25 bore, which yields 245.3 N. The adjustable cushion matters most when cycling at high speeds or moving heavy loads, as it prevents harsh end-stop impacts. Remember that this cylinder does not hold position on air loss; the piston will drift if pressure drops, so fit an external rod lock or pilot check valve if you need to suspend a load. You can mount it via LB foot, FA flange, SDB pivot, or TC trunnion hardware.
Quick checklist
This 20 mm bore cylinder features a 1/8" port and an 8 mm rod. 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.
The -S suffix indicates a built-in piston magnet for use with CMSG, DMSG, or EMSG position switches. It does not include a locking mechanism; the air cushion only decelerates the piston near stroke end. For vertical loads, you must add an external rod lock or pilot check valve to prevent drifting when air pressure is lost.
