New energy vehicle bearings

The bearings used in new energy vehicles (NEVs) differ significantly from those in traditional vehicles, especially in the electric drive system. Compared to traditional automotive bearings, NEV bearings offer superior performance and quality. Below are the common types of motor bearings and their characteristics:

1.Deep Groove Ball Bearings
Features: Capable of simultaneously handling radial and axial loads. High-speed, low friction, and low noise make them suitable for high-speed motors.
2.Cylindrical Roller Bearings
Features: Can bear larger radial loads, with a slightly lower speed than deep groove ball bearings, suitable for medium to high-speed motors.

Technical Requirements for Motor Bearings:
1.High-speed Performance: Capable of speeds reaching 15,000-20,000 RPM or higher, ensuring smooth operation.
2.Low Friction and Noise: Low noise enhances vehicle comfort during motor operation, while low-friction bearings reduce energy loss and extend driving range.
3.High-temperature Resistance: High-speed motor operation generates significant heat, requiring bearings with excellent heat resistance to ensure stable vehicle performance.
4.Long Lifespan: High-quality bearings reduce maintenance frequency and enhance durability.

New energy motor bearings are high-tech, precision-engineered products, and their performance directly impacts the overall efficiency and market competitiveness of new energy vehicles.
