The AirTAC Airtac MIC Cushioned Mini Cylinder MIC32X300SCM is a genuine double acting + cushion round-body mini air cylinder with a Ø32mm bore and 300mm stroke, 1/8" air ports and a stainless-steel barrel and rod for mildly corrosive environments.
Delivering 402.2 N of push force at 0.5 MPa, this double-acting round-body mini cylinder handles heavier duty cycles within a compact footprint. The stainless-steel barrel and piston rod resist mild corrosion and washdown environments. It features a 1/8 inch air port and a 300 mm stroke, making it a robust choice for mid-range automation. A CM round rear cover provides specific mounting and port orientation flexibility.
The defining feature of the MIC series is the adjustable air cushion at both ends. By turning a needle valve, you tune the deceleration to absorb end-of-stroke shock at high speeds, protecting the load and cutting noise. Based on the 0.5 MPa push rating, this bore yields a safe working load of roughly 241 N, lifting about 20.5 kg vertically with a 2:1 safety margin. The unit includes an -S magnet for CMSG, DMSG or EMSG position switches.

| 0.7 MPa | 563 N | 484 N |
| Max (@1.0 MPa) | 82 kgf | |
Actual usable force is lower than theoretical due to friction and back-pressure. Size with a safety 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.
Pushes medium-weight cartons off a high-speed belt line, using the adjustable cushions to stop the 300 mm stroke smoothly without jarring the goods.
Drives cardboard flaps down on an automated case erector, handling the 402.2 N push requirement while the stainless build shrugs off dusty debris.
Indexing small components into a pallet fixture at speed, where the needle-set deceleration protects the tooling from impact damage.
When sizing this 32 mm bore, stepping down to an MIC25X300 lowers the push force to 245.3 N at 0.5 MPa, while stepping up to an MIC40X300 raises it to 628.3 N. Choose this 32 mm model when moving loads near that 241 N safe working threshold at high travel speeds, where the adjustable needle cushions excel at smoothing stops. Note that the air cushion only decelerates the piston near the stroke end; it does not lock or hold position. If your process requires the load to stay put on air loss, add an external rod lock or a pilot-operated check valve. Mounting options include LB foot, FA flange, SDB pivot and TC trunnion brackets.
Quick checklist
This double-acting cylinder has a 32 mm bore, a 300 mm stroke and a 1/8 inch air port. It generates 402.2 N push and 345.6 N pull at 0.5 MPa, or 563 N push and 483.8 N pull at 0.7 MPa. The theoretical maximum force is 82 kgf at 1.0 MPa.
No, the adjustable air cushion only decelerates the piston near the end of the stroke; it is not a brake or lock. The piston will drift on air loss. For vertical loads, you must use an external rod lock or pilot check valve. The -S magnet allows CMSG, DMSG and EMSG sensors for position tracking.
