When selecting bearings for EV motors in new energy vehicles, the following factors need to be considered:

Speed and accuracy: EV motors for new energy vehicles are typically used for high-speed rotation, therefore requiring high-speed, precise, and reliable bearing support. When selecting bearings, it is necessary to consider the requirements of speed and accuracy, as well as the usage conditions and application scenarios.

Load and load distribution: EV motors for new energy vehicles are usually used for light and low loads, therefore requiring bearing support with high rigidity, low friction, and small sealing torque. When selecting bearings, it is necessary to consider the requirements of load and load distribution, as well as the usage conditions and application scenarios.

Working temperature and lubrication: New energy vehicle EV motors need to operate in high-temperature environments, therefore requiring high heat resistance, high temperature resistance, and fire-resistant bearing support. When selecting bearings, it is necessary to consider the requirements of working temperature and lubrication, as well as the usage conditions and application scenarios.

Brand and Quality: Choosing well-known brands and reliable bearings can ensure the reliability and longevity of bearings, and reduce maintenance costs.

Usage conditions and application scenarios: Different usage conditions and application scenarios require different types of bearing support, so it is necessary to choose the appropriate bearing type based on the usage conditions and application scenarios.
