About the Airtac MICD Air Cushion Double Rod Mini Cylinder MICD40X80
Balanced force defines this AirTAC round-body mini cylinder, as a through-rod exits both covers to deliver an equal 527.8 N of thrust and pull at 0.5 MPa. The twin-rod layout inherently resists rotation, while the adjustable air cushion at each end soaks up high-speed shock before the piston strikes the cover.
Built with a stainless-steel barrel and rod for mild washdown resistance, this double-acting actuator runs on a 1/4" port at speeds of 30-800 mm/s. Because a rod occupies both faces, the effective working area is identical in both directions, yielding a safe working load of about 317 N or a 2:1 vertical lift capacity near 26.9 kg. Note this non-magnetic SKU cannot host position sensors.

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 Ø40 bore is a larger, non-ISO-6432 size.
Theoretical Output Force (Ø40mm)
| Pressure | Force (both ways) |
|---|---|
| 0.5 MPa | 528 N |
| 0.7 MPa | 739 N |
| Max (@1.0 MPa) | 108 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 MICD40X80 Is Used
Balanced Transfer Pusher
Drives a guided transfer carriage on a conveyor using equal 527.8 N push and pull forces, preventing rotation while the air cushions absorb the shock of rapid 80 mm reversals.
High-Speed Flap Folder
Folds heavy carton flaps at speed where the twin rods keep the folding blade perfectly aligned, and the dual adjustable cushions prevent slamming at the end of each stroke.
Vertical Lift Gate
Raises and lowers a 25 kg access gate using the through-rod design for symmetrical lifting force, relying on an external check valve to hold the load since the cushions only decelerate.
Is the Airtac MICD Air Cushion Double Rod Mini Cylinder MICD40X80 the Right Cylinder?
When sizing this 40 mm bore, dropping down to the MICD32 cuts the 0.5 MPa force to 345.6 N, while no larger standard MICD bore exists above it. The double-rod plus needle-cushion combination is ideal when you need symmetrical pushing and pulling without end-of-stroke banging at high velocity.
Mounting options include LB foot, FA flange, and TC trunnion blocks, but the SDB pivot block is not offered on this twin-rod variant. Remember that the air cushion only decelerates the load near the stroke ends and does not function as a brake; if you need to hold a vertical load during air loss, install an external rod lock or pilot check valve. Furthermore, this specific SKU lacks a magnet, so CMSG, DMSG, or EMSG switches cannot be fitted.
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 MICD40X80 FAQ
Because the double-rod design uses the rod-side area on both faces, force is equal both ways: 527.8 N at 0.5 MPa, 738.9 N at 0.7 MPa, and a maximum theoretical output of 107.6 kgf at 1.0 MPa.
No, this specific SKU does not include a magnet, so CMSG, DMSG, or EMSG switches cannot be used. You would need the -S variant for sensing. The cylinder features a stainless steel build with a 1/4" port and adjustable air cushions at both ends to manage high-speed shock.
