Bearings are important components in modern machinery and equipment, and are known as the "joints" of industrial machinery. On June 27, in Yandian Town, Linqing City, Liaocheng, the hometown of bearings, every bearing manufacturer is running at full capacity.


How much economic benefit can "small parts" play?


As the "Hometown of Bearings in China", Linqing City gave the answer: Liaocheng Bearing Industry Cluster was formed in the early 1980s, and now the bearing market in Yandian Town is the largest bearing professional with the most complete varieties and the largest number of participants in the country. The annual market transaction volume exceeds 20 billion yuan; the Linqing Bearing Industry Cluster has become one of the five largest bearing industry clusters in the country.


Looking back on the past, the development of Linqing Bearings was not smooth sailing. Faced with the extrusion of high-end products from large foreign brands and large domestic enterprises, it was once in trouble.


How to crack the bottleneck? The "helmsmen" of the bearing industry aim at intelligence. They accelerated the industrial transformation, vigorously promoted the application of informatization and intelligent technology, built digital workshops, and promoted the transformation of bearing "manufacturing" to "intelligent manufacturing" with a new round of technological transformation.


Bearing production line


In key parts of industrial robots, medical manipulators and other products, bearings bear comprehensive loads in axial, radial, and overturning directions, among which thin-walled bearings are the core accessories. Shandong Bote Bearing Co., Ltd. is an enterprise specializing in the production of thin-walled bearings.


"We have increased investment and focused on the in-depth research and development of bearing products, and a number of products have filled the domestic gap. Among them, thin-walled bearings have ranked first in the domestic market for three consecutive years, and are also exported to more than 20 countries and regions."


Yang Haitao, general manager of the company, told reporters that the competitive product "thin-wall bearing" is small in size and light in weight, which meets the requirements of modern machinery for compact, simplified and lightweight slewing mechanism design, and has a promising market prospect. "In the past, we fought for resources and low costs. Now the situation has changed. We must fight for innovation and research and development."

In recent years, Linqing's bearing industry has attached great importance to scientific and technological innovation, R&D and design, and has won 4 China Machinery Industry Science and Technology Awards. It has 16 national high-tech enterprises, 6 provincial enterprise technology centers, and provincial "one enterprise, one technology". There is 1 R&D center enterprise, 7 provincial-level "one enterprise, one technology" innovation enterprises, with 210 invention and utility model patents; 7 enterprises have participated in the formulation and revision of 21 national and industry standards.


After more than 40 years of development, from "scattered blossom" to "beaded into a chain", Linqing's bearing industry is realizing a transformation from large to strong, from strong to specialized and new, and marches into a new era of high-quality development.
