New energy vehicle supporting bearing YYL03A

The supporting bearings for new energy vehicles are crucial components in automobiles.

Technical requirements:

High precision: In order to ensure the precise assembly and operation accuracy of automotive components, automotive supporting bearings usually need to have high dimensional accuracy and rotational accuracy to ensure the concentricity and perpendicularity of rotating parts, reduce vibration and noise.

High reliability: When driving in various complex road conditions and environments, bearings need to be able to maintain stable performance under long-term high loads, high-speed operation, as well as harsh temperature, humidity, and other conditions, with a long service life and low failure rate.

Low friction: Reducing the friction coefficient of bearings can improve the fuel economy of cars and reduce energy loss. Meanwhile, low friction can also lower the operating temperature of bearings and extend their service life.
