This is a replacement one-way bearing for the Align 600 and 600N line of helicopters. It fits onto the one-way bearing under the main gear and the transmits the power from the main shaft to the main drive gear and autorotation tail drive gear and allows the rotor system to rotate freely if the motor stops turning.

The original bearing is 18.15 mm outside diameter, the bearing I bought is 18.05 mm outside diameter.
Since the original hub has a diameter of 17.9mm, the bearing assembles without interference, which leads to the use of glue, increasing the risk of failure in flight.
I do not recommend buying this spare part, I recommend buying the complete AGNH60200 set if you want to avoid problems.
