Advantages of NINE STAR hybrid ceramic bearings

NINE STAR hybrid ceramic bearings are constructed of steel rings and silicon nitride (Si₃N₄) balls, which are approximately 40% of the density of steel. This gives the bearings a lower inertia and better high-speed capability than standard bearings. The lower inertia results in less loading on the raceway and provides superior performance during rapid acceleration and deceleration. The silicon nitride balls also have a lower coefficient of friction so they generate less heat at high speed, greatly improving the life of the grease and the bearing. As a result, the bearings are less sensitive to temperature changes and high temperature operating conditions that can affect both running accuracy and internal clearance.

NINE STAR hybrid ceramic bearings are ideal for use in electric motors and generators that are prone
to stray electric currents. The bearing design insulates the inner ring and the outer ring of the bearing, effectively preventing the flow of stray currents. This helps to avoid arc-pits and secondary damage that can result in increased noise and vibration, heat generation, lubricant breakdown, and premature failure of the bearing.
