Electrically Insulated Ball Bearings
Sealed
Good for use in electric motors and power generators, these bearings have ceramic balls that insulate against stray current to prevent damage to the bearing. The ceramic balls generate less heat than steel balls, so they require lubrication less frequently.
Sealed bearings block out dust and other contaminants better than open and shielded bearings but retain the most heat.
