The AirTAC Airtac MIC Cushioned Mini Cylinder MIC20X172SU is a genuine double acting + cushion round-body mini air cylinder with a Ø20mm bore and 172mm 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.
Built for rapid cycling, the AirTAC MIC20X172SU relies on a needle-set variable air cushion at both ends to absorb end-of-stroke shock, outperforming fixed bumper mini cylinders. This double-acting, round-body stainless steel actuator carries a 172 mm stroke and uses a 1/8 inch port. Its U-style 90-degree rear cover simplifies port and mounting orientation in tight spaces.
Delivering 157 N of push force and 131.9 N of pull force at 0.5 MPa, it suits light-to-medium duty tasks. The stainless barrel and rod resist mild corrosion and washdown environments. Because the bore is Ø20, it conforms to the ISO 6432 mounting interface, dropping directly into standard mini-cylinder brackets. This specific configuration includes a piston magnet (-S) for CMSG, DMSG or EMSG sensor integration. Based on the 0.5 MPa push figure, it handles a safe working load of roughly 94 N, lifting about 8 kg vertically with a 2:1 margin.

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.
Ideal for swiftly routing small parcels on a conveyor. The adjustable air cushion halts the 172 mm stroke gently, preventing package damage even at high cycle rates.
Ejects lightweight machined parts from a fixture. The 157 N push force clears debris or parts reliably, while the stainless build handles light coolant splash.
Opens and closes access hatches on storage bins. The U-style 90-degree cover aids mounting, and the cushion prevents the lid from slamming shut abruptly.
When sizing this actuator, step down to the Ø16 bore for lighter loads, but note its lower 100.5 N push force at 0.5 MPa. If your application requires more thrust, stepping up to the Ø25 bore provides 245.3 N at 0.5 MPa. The adjustable air cushion on the MIC20X172SU is essential when operating at high speeds or moving heavier loads, as it decelerates the piston smoothly without harsh impacts.
Remember that the air cushion only decelerates near the stroke end; it does not function as a lock or brake. If air pressure drops, the piston will drift, so install an external rod lock or pilot-operated check valve for secure load holding. This SKU includes the -S magnet for position sensing, and you can pair it with LB foot, FA flange, SDB pivot, or TC trunnion mounts to fit your frame.
Quick checklist
This double-acting cylinder features a 1/8 inch port and an M8x1.25 male rod 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 maximum of 32 kgf at 1.0 MPa.
Yes, the -S suffix means it has a built-in magnet for CMSG, DMSG, or EMSG switches. The variable air cushion at both ends uses a needle valve to tune deceleration, reducing shock at high speeds. It only decelerates the load and does not lock or hold position on air loss.
