Wajiao Insulated Bearing Technology Achieves New Breakthrough

Recently, Wajiao Group successfully overcame three core technical bottlenecks in the design of insulating bearings, high-efficiency and high-precision manufacturing, and comprehensive testing and inspection. Previously, the production of high-end motor insulating bearings in this field was long monopolized by foreign companies. The Wajiao team developed a special ceramic coating formula through independent research and optimized plasma spraying processes, overcoming the challenge of high-precision grinding with minimal coating damage. They also established the first domestic model for accelerated life testing under electrical and mechanical stress. Currently, this technical achievement has been applied to fields such as rail transit traction motors, wind turbines, and large industrial frequency-converting motors, achieving domestic substitution for insulating bearings, breaking foreign technological barriers, and ensuring the safety and stability of China’s major equipment industry chain and supply chain.
