About the Airtac MICD Air Cushion Double Rod Mini Cylinder MICD25X40S
Equal force in both directions defines this AirTAC MICD25X40S double-acting cylinder, achieved by routing a Ø10 mm piston rod through both end covers. It generates 206.1 N at 0.5 MPa on both the extend and retract strokes, while adjustable air cushions at each end soak up high-speed end-of-travel shock. The stainless-steel round barrel and rod resist mild corrosion and washdown environments.
Built to the ISO 6432 mini-cylinder mounting interface, this Ø25 mm unit drops into standard brackets and clevises. The included -S piston magnet enables CMSG, DMSG and EMSG position sensing. For sizing, a safe working load is roughly 124 N (about 60 percent of the 0.5 MPa figure), translating to a vertical lift of about 10.5 kg with a 2:1 margin.

Where the Airtac MICD Air Cushion Double Rod Mini Cylinder MICD25X40S Is Used
Diverting Gate Actuation
Drives a bi-directional sorting flap on a packaging line, using the twin rods to resist rotation and the air cushions to soften impacts at high cycle rates.
Pick-and-Place Transfer
Shifts light electronic components horizontally with equal 206 N force both ways, while the rear rod trips an EMSG sensor to confirm stroke completion.
Pallet Stopper Mechanism
Raises and lowers a physical stop block on a roller conveyor, relying on the adjustable cushions to prevent banging when halting loads.
Is the Airtac MICD Air Cushion Double Rod Mini Cylinder MICD25X40S the Right Cylinder?
At 0.5 MPa this 25 mm bore yields 206.1 N both ways; stepping down to a 20 mm MICD drops the equal force to 131.9 N, while moving up to a 32 mm MICD raises it to 345.6 N. Choose this double-rod plus adjustable-cushion combination when you need guided, non-rotating motion and shock absorption at speeds up to 800 mm/s. The 1/8 inch port matches the standard bore sizing.
Remember that the air cushion only decelerates the piston near the stroke end and does not lock or hold the load. If air pressure drops, the piston will drift; use an external rod lock or pilot check valve for true load holding. Mount via LB foot, FA flange or TC trunnion, as the SDB pivot block is not available on this double-rod variant.
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 MICD25X40S FAQ
Because the double rod occupies both sides, force is equal both ways: 206.1 N at 0.5 MPa, 288.5 N at 0.7 MPa, and a maximum theoretical 42.0 kgf at 1.0 MPa. The air port is 1/8 inch.
No. The adjustable air cushions only decelerate the piston near the end of stroke; they do not act as a brake or lock. The piston will drift on air loss, so you need an external rod lock or pilot check valve to hold a suspended load. The -S magnet allows CMSG, DMSG and EMSG sensors for position feedback.
