Electric cars are powered by electricity from batteries and do not have an engine like gasoline cars. However, electric cars do have some moving parts that require bearings, such as the wheels and motors. High speed, high temperature, frequent starting and stopping accompanied by the impact are the main working conditions of electric vehicle drive motors, so new energy drive motor bearing design needs to meet the conditions of good sealing performance, high-temperature resistance, low-temperature resistance, adapt to repeated start-stop performance, a certain amount of axial impact load, etc. Yuhong bearings are good choices.
