About the Airtac MICD Air Cushion Double Rod Mini Cylinder MICD32X20S
Built for fast, guided and shock-sensitive moves, the AirTAC MICD32X20S is a round-body stainless-steel mini cylinder featuring a double-rod construction. Because a rod exits both ends, the piston uses the pull-side area on every stroke, delivering an equal 345.6 N of force at 0.5 MPa in both directions. The twin-rod layout also resists rotation, while the rear rod can trip a switch or carry a stop. An adjustable air cushion at each end soaks up end-of-stroke shock at high speed, protecting your payload.
The stainless barrel and rod resist mild corrosion and washdown environments. This 32 mm bore, 20 mm stroke variant is a non-ISO-6432 size and features a 1/4" port with an M10x1.25 male rod thread. The built-in piston magnet (-S) supports CMSG, DMSG and EMSG sensors. For sizing, a safe working load is roughly 207 N (about 60% of the 0.5 MPa force), which translates to moving about 17.6 kg vertically each way with a 2:1 safety margin.

Specifications follow the official AirTAC MI/MIC (ISO 6432) datasheet. Barrel & rod: stainless steel (round-body, riveted construction). Thread options: PT (blank) / G. Note: the Ø32 bore is a larger, non-ISO-6432 size.
Theoretical Output Force (Ø32mm)
| Pressure | Force (both ways) |
|---|---|
| 0.5 MPa | 346 N |
| 0.7 MPa | 484 N |
| Max (@1.0 MPa) | 70 kgf |
Double-rod: a rod exits both covers, so output force is equal in both directions (rod-side area used).

Where the Airtac MICD Air Cushion Double Rod Mini Cylinder MICD32X20S Is Used
Package Diverting
Equal push and pull force makes this cylinder ideal for diverting parcels on a high-speed conveyor, where the twin rods prevent twist and the cushions absorb rapid stops.
Pick And Place
Moving about 17.6 kg vertically each way with a 2:1 margin, the guided double-rod design lifts small parts smoothly while the adjustable cushions protect sensitive components.
Stopper Gate
The rear rod can trip a switch or act as a secondary stop, while the front rod halts pallets, using the 345.6 N equal force to hold position against moving loads.
Is the Airtac MICD Air Cushion Double Rod Mini Cylinder MICD32X20S the Right Cylinder?
When sizing this 32 mm bore, step down to the 25 mm MICD for lighter loads (206.1 N at 0.5 MPa) or step up to the 40 mm model for heavier jobs (527.8 N at 0.5 MPa). Choose this double-rod plus adjustable-cushion combination when you need equal force both ways and rapid deceleration without end-of-stroke banging. Remember that the air cushion only decelerates the piston near the stroke end; it is not a lock or brake. If the air supply drops, the piston will drift. To hold a load securely, add an external rod lock or a pilot-operated check valve.
For mounting, you can use LB foot brackets, FA flanges or TC trunnions, but the SDB pivot-block is not available on this double-rod variant. The included -S magnet allows you to fit CMSG, DMSG or EMSG switches for position sensing.
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 MICD Air Cushion Double Rod Mini Cylinder MICD32X20S FAQ
The force is equal both ways because a rod exits both ends. It provides 345.6 N at 0.5 MPa, 483.8 N at 0.7 MPa, and a maximum theoretical force of 70.5 kgf at 1.0 MPa.
Yes, the -S suffix means it has a built-in magnet for CMSG, DMSG or EMSG switches. It also features an adjustable air cushion at both ends that decelerates the piston at high speed, though it is not a lock.
