in ball bearings.
The ceramic material is an insulating material.
Electrolytic Corrosion Proof Fan has been designed to prevent the
electrolytic corrosion of ball bearings in the fan, but this does not
guarantee that the fan will operate normally under conditions where
there is strong electromagnetic noise.
Please be sure to fully evaluate the value of fan malfunction due to noise
in advance.
