The 3.3-meter-diameter rotary shield plug bearing, manufactured by Liaoning General Machinery Group, has successfully passed five critical tests: appearance inspection, dimensional accuracy, cleanliness, ultrasonic testing, and static load testing. It has recently been shipped and will be installed in a fast neutron reactor in China. This marks a significant milestone for the company and highlights its capability in producing high-precision components for advanced nuclear technology.
As one of the most important energy projects under China's National 863 Program, the Fast Neutron Reactor is set to play a key role in power generation and the production of valuable nuclear fuel. The project is being led by China First Heavy Machinery Group Co., Ltd., which was entrusted by the China Institute of Atomic Energy to manufacture the necessary equipment. The performance of the rotary shield plug bearing is crucial for the smooth operation of the reactor. Liaoning General Machinery Group, as a long-standing supplier to China's No. 1 Heavy Machinery Group, has proven its technical expertise and reliability over the years.
In 2002, Liaoning General Machinery Group stood out among other domestic manufacturers due to its strong R&D capabilities and diverse product portfolio. It was selected as the specialized manufacturer for this critical component. The company's history dates back to the Anshan Bearing Factory, which was designated as a key producer of bearings by the former Ministry of Machinery. After a major restructuring in October 1998, the company reorganized its operations into a "one factory and three lines" model, focusing on large bearings, oil-free air compressor pressure vessels, and precision machining. Over time, it acquired six companies, expanding its scale and integrating resources in terms of personnel, technology, and capital.
It is worth noting that compared to conventional bearings, these rotary shield plug bearings are designed to operate without any human intervention once installed. This makes the materials, manufacturing processes, and quality control extremely stringent. A rigorous design, production, installation, and operational system must be in place to ensure absolute reliability. After signing the contract and quality assurance agreement in 2002, the company conducted thorough technical preparations and entered the design and manufacturing phase. With the guidance and full supervision of experts from the China Institute of Atomic Energy and China First Heavy Machinery Group, Liaoning General Machinery Group’s team worked tirelessly to successfully develop and produce the rotary shield plug bearing.
