Bearings, known as the “joint of industry”, are important basic parts in the equipment manufacturing industry, small to watches, large to cars, ships can not be separated from it. Its accuracy and performance play a decisive role in the life and reliability of the host.
Linqing City, located in the west of Shandong Province, is known as the “town of Bearings in China”, which has developed into a huge industrial cluster with Yandian, Panzhuang, Tangyuan and other towns as the center, radiating the surrounding counties and urban areas and even the northern region of China. Linqing small and medium-sized bearing industrial cluster has also been selected as a national small and medium-sized enterprise characteristic industrial cluster. Nowadays, Linqing bearing industry is changing rapidly from “manufacturing” to “intelligent manufacturing”.
Products can be “the thinnest in China”
“From a diameter of more than one meter to a few millimeters of bearings, we can achieve the ‘thinnest in China.’” Recently, at the 8th China Bearing, spare parts and special Equipment Exhibition held in Linqing City, Shandong Bote Bearing Co., Ltd. sales manager Chai Liwei showed their fist products to the exhibitors.
In the key parts of industrial robots, medical robots and other products, densely distributed bearings bear the axial, radial, overturning and other directions of the comprehensive load, of which thin-wall bearings are the core parts, Bott bearings is a professional production of thin-wall bearings enterprises. “In the past, it was about resources and low costs, but now it’s about innovation and research and development.” In the BOT bearing R & D center, Yang Haitao, general manager of the company, sighed.
In recent years, Bote bearing has increased investment in scientific research, has obtained 23 utility model patents, and its thin-wall bearing series products have the first domestic market share for many years, and are exported to more than 20 countries and regions.
In the spacious and bright workshop of Tangyuan Town Haibin Bearing Manufacturing Co., LTD., an automatic assembly line runs in an orderly manner, and a set of fine bearing products “line up” in turn go down the production line. “Don’t underestimate this little gadget, although its size is only 7 millimeters, it gives us the confidence to compete with foreign companies.” Production manager Yan Xiaobin introduces the company’s products.
In order to continuously improve the competitiveness of enterprises, Haibin bearing has cooperated with many colleges and universities and scientific research institutes in China, and has successively developed Ⅱ thrust spherical roller, multi-arc roller, high-speed elevator bearing special roller and other products, becoming a dark horse in the industry.
In view of the pain points such as serious homogenization, weak brand influence and lack of core competitiveness prevalent in the bearing industry, on the one hand, Linqing City strives to cultivate a number of fist products and well-known brands with high visibility by optimizing the quality control system and production management system, introducing technical talents, etc. On the other hand, accelerate scientific and technological innovation and industrial transformation, and promote the transformation of the bearing industry from large to strong, from strong to “specialized and special”. Last year, Linqing City added 3 provincial gazelle enterprises and 4 individual champion enterprises (products); There were 33 new state-level high-tech enterprises.

There are more than 400 companies on the cloud
“After the company entered the bearing industrial park, more than 260 new intelligent equipment, more than 30 intelligent connections, through digital upgrading, equipment ‘on the cloud’, the production, orders, inventory, customers all achieve digital management, not only save labor costs, but also greatly improve the efficiency of production management…” In the production workshop of Shandong Haisai Bearing Technology Co., LTD., located in Panzhuang Town, Wang Shouhua, the general manager, talked about the convenience brought by the intelligent transformation to the enterprise.
Panzhuang Town, located in Linqing bearing market and forging base “throat”, is also the first bearing full chain production and processing base in China. “In recent years, we have adopted an enterprise and a policy to promote the integrated development of the bearing industry in a planned and step-by-step manner.” Panzhuang town Party secretary Lu Wuyi said. Panzhuang Town makes full use of the advantages of bearing industry agglomeration and park, chooses some backbone enterprises to create digital transformation models, guides and supports small and medium-sized enterprises to actively participate in, and realizes “machine replacement, industrial line change, equipment core change, and product replacement”.
In the intelligent production workshop, one automatic line runs at high speed, after turning, grinding, milling, drilling, quenching and other processes, one high-precision self-aligning roller bearing goes down the conveyor belt; In the next office building, the 5G smart CNC center is displayed on the large screen, and the whole process of intelligent reporting and scheduling, production progress query, inventory entry and exit, and real-time monitoring of equipment are at a glance… In Shandong Yujie Bearing Manufacturing Co., LTD., the reporter personally felt the scientific and technological charm of “5G smart factory”.
Today, Yujie bearing’s “circle of friends” has already extended to the world. As the largest medium minor roller bearing manufacturer in China, Yujie bearing series products have ranked first in domestic production and sales for three consecutive years, and exported to 20 overseas countries and regions.
Digital industrialization and industrial digitalization have become the “core code” for the healthy and high-quality development of Linqing bearing industry. Linqing City actively cooperated with CITIC Cloud Network and more than 200 bearing enterprises to build a “cloud axis alliance” to build the digital economic headquarters of China’s bearing industry chain. Up to now, Linqing bearing industry has been on the “cloud” more than 400 enterprises, more than 5,000 sets of equipment, Linqing bearing industry digital workshop solutions selected as a typical case of national digital transformation.
The industrial chain extends to surrounding counties and urban areas
In recent years, Linqing City around the promotion of science and technology strong city, give full play to the role of financial funds “four or two”, with financial leverage science and technology in-depth innovation, to promote the city’s characteristic bearing industry economic high-quality development.
In the work, Linqing City has vigorously promoted the growth and development of the construction of the bearing innovation and entrepreneurship community through financial investment in state-owned enterprises, and has invested 9 million yuan of supporting subsidy funds to accelerate the transformation of scientific and technological achievements in a market-oriented way.
In addition, Linqing City actively implements the requirements of the superior and the level of awards and subsidies policy, and continues to increase the support for enterprise R&D awards and subsidies. In 2022, a budget of 14.58 million yuan was arranged to support bearing enterprises to carry out scientific and technological research and innovation, involving more than 70 enterprises on the plan. 2023 to further increase support, as of now the budget of 10.5 million yuan for bearing enterprises scientific and technological innovation research and development.
“Here the industrial chain is more complete, the level of science and technology is more advanced, the talent force is stronger, the market is more complete, more conducive to the development and growth of enterprises, the overall relocation of the factory, this decision we did right!” Speaking of the choice made at the beginning, Chen Qian, manager of Shandong Taihua Bearing Co., LTD., said that he did not regret it.
Shandong Taihua Bearing Co., Ltd. is the first state-owned holding enterprise in the bearing industry attracted by Panzhuang Town, which is jointly built by Guiyang Yongli Bearing Co., Ltd. and Guizhou Taihua Jinke Technology Co., LTD. In 2020, the company moved from Guiyang to Panzhuang Town across 1,500 kilometers.
“More than 10 large trucks carried out equipment transportation every day, and it took almost 20 days to move it, and more than 150 large equipment were moved only.” Chen Qian remembers the scene of the move.
The overall relocation of old state-owned enterprises is the complete bearing industry chain and industry-leading bearing enterprises and platforms in Linqing. At present, the bearing industry cluster of Linqing City is mainly concentrated in the three towns of Tangyuan, Yandian and Panzhuang, and the industrial intensive area of about 8 kilometers long from north to south and about 5 kilometers wide from east to west has cultivated more than 5,000 large and small production and processing enterprises.
Linqing bearing combined with the surrounding counties and urban areas formed a complete industrial chain of forging – turning – grinding + steel ball, retainer – finished product – market production, processing and sales. For example, Dongchangfu District bearing retainer annual sales of 12 billion pairs, accounting for more than 70% of the industry, is the country’s largest bearing retainer production base; Donga County is the largest steel ball production base in Asia, with a domestic market share of more than 70%. Guanxian bearing forging accounted for more than a quarter of the national market.
