The supporting bearings developed by ZWZ Group for the reducer of new energy off-road vehicles have been verified by customers during installation, and their performance has reached the same level as high-end bearings of internationally renowned enterprises. They have started mass production at Liaoning Bearing Company.

This customer is a leading domestic enterprise in new energy motor systems, developing and supporting advanced electric drive core components, assemblies, and systems for global customers, covering both passenger and commercial vehicles. The bearing project for the reducer of new energy off-road vehicles is a national project jointly developed by the customer, ZWZ Group, and well-known universities in China. ZWZ Group is responsible for bearing design and processing, aiming to provide bearings for new energy vehicles. The bearings are required to have high speed, low vibration, and long service life performance requirements.

The new energy vehicle reducer bearing developed by ZWZ has been verified by the customer, and the working speed of the bearing reaches 20000rpm. The bearing life has reached 10 times the theoretical calculation life and has not yet failed. "Assistant General Manager of the Automotive Bearing Business Unit, Wen Shaoying, introduced that the customer's new energy off-road vehicle reducer requires all components to be domestically produced, and the bearing performance should reach the same level as high-end foreign products. At present, the customer has placed a batch of bearing orders with the tile shaft.

As an alternative to imported new energy vehicle bearings, in order to meet the accuracy requirements of high speed, high bearing capacity, low friction, low noise, and long service life, we have formed a research group to repeatedly verify and optimize the processing technology, forming a complete new energy vehicle bearing processing process, ensuring the stability and consistency of product processing quality, and achieving batch processing of high-precision grade new energy vehicle bearings According to Man Jingyu, Assistant General Manager of Liaoyang Branch of Automobile Bearings, the branch currently has multiple advanced automatic production lines in China, and has jointly developed and successfully mass-produced various models of new energy vehicle bearings with several well-known domestic customers in the new energy vehicle industry. It has achieved technological innovation in high-speed and high-performance design and testing technology, helping ZWZ's new energy vehicle bearing market continue to expand.
