Ceramic Bearing Successful Case: Perfect Application in New Energy Vehicle Electric Drive System

With the continuous upgrading of new energy vehicle technology, the electric drive system puts forward higher requirements for bearing speed, insulation performance and durability. Traditional steel bearings are prone to electric corrosion, high-temperature wear and grease aging failure in high-voltage and high-speed operating environments, which affects the stability and service life of the vehicle power system. Our customized hybrid ceramic bearings have successfully solved this industry pain point and been widely applied in the mass production of high-performance new energy vehicles.

The hybrid ceramic bearing products we supply adopt high-purity silicon nitride ceramic balls and high-precision steel rings, matched with high-speed resin cages and special long-life lubricating grease. The product has excellent electrical insulation performance, which can completely isolate the current inside the electric drive system and avoid bearing pitting and wear caused by electric corrosion. At the same time, the low friction coefficient of ceramic materials reduces the operating resistance of the bearing, effectively improving the energy conversion efficiency of the vehicle and reducing overall energy consumption.

In actual vehicle road tests and long-term operation verification, our ceramic bearings maintain stable operation under extreme conditions of 20,000+ RPM high speed and -40℃ to 180℃ variable temperature. Compared with traditional bearings, the service life of the electric drive system is extended by more than 3 times, the equipment failure rate is reduced by 85%, and the maintenance cost is greatly reduced. Up to now, we have provided supporting bearing solutions for many new energy vehicle manufacturers in Europe, Southeast Asia and North America, with stable product quality and unanimous customer recognition.
