MRC® hybrid ceramic ball bearings combine traditional steel rings matched with non-conductive silicon nitride (ceramic) balls offering inherent insulating properties to prevent electrical arcing and associated surface damage to raceways, excessive noise, and premature lubricant aging. They provide ideal “drop-in” replacement solutions within existing design envelopes in such applications as large variable-speed electric motors where electric arcing is prevalent.
Compared with all-steel bearings, these bearings further are lighter, harder, and more durable. They can run at higher speeds and lower operating temperatures and exhibit superior wear resistance to contribute optimized performance and longer service life.
Their ceramic balls are 40% less dense than steel balls for reduced centrifugal force and friction, allowing them to run faster and cooler; harder than steel for enhanced wear resistance against hard particles, contaminants, and vibration; and highly inelastic for increased bearing stiffness and reduced deflection under load to promote reliable performance.
