About the Airtac MICD Air Cushion Double Rod Mini Cylinder MICD40X80S
Built for high-speed guided motion, this double-acting stainless round-body mini cylinder features a through rod that exits both covers, delivering equal force of 527.8 N at 0.5 MPa in both directions. The twin-rod architecture resists rotation, while adjustable air cushions at each end soak up end-of-stroke shock. Its stainless barrel and piston rod withstand mild corrosion and washdown environments.
Equipped with a 1/4 inch port and an M12x1.25 male rod thread, the 40 mm bore operates at speeds from 30 to 800 mm/s. Because a rod occupies each side, the effective thrust matches the pull area, yielding a safe working load of about 317 N or a 26.9 kg vertical lift with a 2:1 margin. The built-in magnet (-S) supports CMSG, DMSG and EMSG sensors for position detection.

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 MICD40X80S Is Used
Product Diverting
Drives a dual-sided diverting arm on a packaging line, using the equal both-ways force and twin-rod anti-rotation to push boxes smoothly at high speed.
Vertical Lowering
Lowers a 25 kg fixture with a 2:1 safety margin, relying on the adjustable air cushions to prevent slamming at the bottom of the 80 mm stroke.
Pallet Stopper
Acts as a high-cycle pallet stop gate where the back rod trips an external limit switch, absorbing shock via the needle-set cushions.
Is the Airtac MICD Air Cushion Double Rod Mini Cylinder MICD40X80S the Right Cylinder?
When sizing this 527.8 N (at 0.5 MPa) bore, step down to the MICD32 (345.6 N) for lighter loads, or note that 40 mm is the largest available in this cushioned mini series. The double-rod plus adjustable cushion combination is ideal when you need equal push and pull forces alongside shock absorption at high cycle rates. Mount using LB foot, FA flange or TC trunnion brackets, as the SDB pivot block is not offered on this double-rod variant.
Remember that the air cushion only decelerates the piston near the stroke end and does not function as a brake. If your application must hold a vertical load during air loss, add an external rod lock or pilot-operated check valve. Position sensing requires the included -S magnet to pair with CMSG, DMSG or EMSG switches.
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 MICD40X80S FAQ
The force is equal both ways because a rod exits each end. It provides 527.8 N at 0.5 MPa, 738.9 N at 0.7 MPa, and a maximum theoretical force of 107.6 kgf at 1.0 MPa.
No, the adjustable air cushions only decelerate the piston near the stroke ends and do not act as a lock. The -S magnet enables position sensing, but you need an external rod lock to hold loads during air loss.
