How two bearings mirror upgrading of China’s manufacturing
How two bearings mirror upgrading of China’s manufacturing
By Li Xinping, Wang Zheng, Ding Yiting, People’s Daily
Bearings are considered as “joints” of industries.
Recently, the Liu’ao offshore wind farm in Zhangzhou, southeast China’s Fujian province, which features the application of 16-MW offshore wind turbine units, was put into full-capacity operation and connected to the grid for power generation. The bearings of the turbine units were independently developed in China.
Meanwhile, a tunnel boring machine equipped with a Chinese-manufactured main bearing, which comes with a diameter of over three meters, was instrumental in building the Suzhou Metro Line 6 in Suzhou, east China’s Jiangsu province.
These two bearings exactly mirror the solid strides in China’s manufacturing over the past 75 years since the founding of the People’s Republic of China.
The bearings used on the 16-MW offshore wind turbine units were produced by LYC Bearing Corporation. “We were incapable of producing high-end bearings over 10 years ago, but we were determined to crack this hard nut,” said Wang Xinying, chairman of the company.
To strengthen its capabilities, LYC set up Chinese national-level key laboratories and other innovative platforms. It also cooperated with Tsinghua University and other institutions of higher learning to leverage their strength.
As a result, it launched a wide range of new products, such as bearings for new energy vehicles (NEVs), wind turbine units, and for rail transit. These products have been employed by important equipment such as the Chang’e series lunar probes, the Tiangong Space Station, and the Five-hundred-meter Aperture Spherical Radio Telescope (FAST).
While LYC is striving for excellence in manufacturing high-end bearings, China Railway Construction Heavy Industry Corporation Limited (CRCHI) is focusing all of its energy on the development of tunnel boring machine (TBM) bearings.
In 2019, CRCHI set up a dedicated research and design institute to develop main bearings for TBMs, the “final piece of the puzzle” in China’s goal to fully localize its TBM industry. After three years, the institute finally developed a TBM bearing with a diameter of over nine meters.
“This main bearing, the largest and heaviest in the world, can be used in the largest TBMs currently available,” said Liu Feixiang, CRCHI’s chief scientist.
“In the past, what we could do was decided by what equipment we had, but now we can manufacture equipment for whatever task is needed,” Liu added.
Behind the two bearings lies the strong confidence stemming from China’s complete manufacturing system.
In 1949, China’s first batch of molten steel was produced by Ansteel in northeast China, and today, China has maintained the world’s largest steel producer for 28 consecutive years, constantly breaking world records in the thickness of steel foils.
In 1956, the first Jiefang truck rolled off the assembly line of Chinese automaker FAW Group. Today, China has been the world’s largest auto production and sales country for 15 consecutive years, while its production and sales of NEVs topped the global market for the ninth year in a row.
China has completed in a just few decades the industrialization process that took developed countries several hundred years. It boasts the world’s most comprehensive industrial categories and a well-rounded industrial system, with its manufacturing spanning 31 major categories, 179 subcategories, and 609 branch categories. For 14 years in a row, the country has remained the world’s top manufacturing hub. In 2023, its value-added manufacturing output accounted for 26.2 percent of its GDP and approximately 30 percent of the global output.
As Chinese enterprises constantly improve their capabilities and extend to the higher end of the industrial chain, more bearing products are hitting the market.
On March 10, a bearing developed by LYC for a 40-meter-aperture radio telescope in the Changbai Mountain area, northeast China’s Jilin province, completed acceptance inspection to support future lunar and deep-space probe missions.
On March 14, the world’s first main bearing for 25 MW wind turbine units successfully rolled off the production line at Luoyang Bearing Science and Technology Co., Ltd. in Luoyang, central China’s Henan province, setting a new record for the highest single-unit capacity in wind turbine bearings.
As products become higher-end, production must also become smarter. CRCHI has built a digital twin of the general assembly facility in one of its industrial parks in Changsha, central China’s Hunan province.
“This is a digital twin image of the front of a TBM’s cutterhead. The varying shades represent the stress and wear on the blades,” said Wang Yongsheng, deputy head of CRCHI’s digital twin research institute. By analyzing the data in real-time, engineers can upgrade the next-generation products in a more targeted manner, Wang added.
In China, mass-produced power battery cells now have an energy density of 300 watt-hours per kilogram, placing them at the forefront of international standards. The silicon-perovskite tandem solar cells made in China have achieved an efficiency of 34.6 percent, continuously setting new world records.
Besides, recent years have seen rapid growth in China’s export of “the new three,” namely, NEVs, lithium-ion batteries and photovoltaic products, with annual exports exceeding 1 trillion yuan ($140.93 billion).
Currently, strategic emerging industries account for about 13 percent in China’s GDP, and China is home to 463,000 high-tech companies. Chinese manufacturing is rapidly advancing toward the high end of the global industrial chain.
Moreover, the penetration rate of digital R&D and design tools in major Chinese enterprises reached 80.1 percent, and 62.9 percent of their key production processes are numerically controlled. Industrial internet has been applied in all major industrial categories, and the steps of industrial digitalization and digital industrialization have been accelerated.
By upgrading traditional industries, expanding emerging industries, and planning for future industries, China is developing new quality productive forces tailored to local conditions, continuously creating new drivers of growth and competitive advantages.

FG Condoles with Families of Stampede Victims, Issues Advisory on Public Events During the Yuletide
FG Condoles with Families of Stampede Victims, Issues Advisory on Public Events During the Yuletide
By: Rabiu Ibrahim
The Minister of Information and National Orientation, Mohammed Idris, deeply sympathizes with the families and loved ones of those who lost their lives in the tragic stampedes that occurred during food distribution exercises in Ibadan, Abuja, and Okija.
“Our thoughts and prayers are with the victims, their families, and all those affected by these unfortunate incidents,” he said.
The Minister said the tragedies are deeply saddening and underscore the importance of ensuring proper crowd management during such charitable activities, especially during the festive season.
While acknowledging the noble intentions of organizers seeking to bring relief to vulnerable members of society, the Minister strongly admonishes all individuals and organizations planning similar events to comply with the directive of the Inspector General of Police, Mr. Kayode Egbetokun on liaising with the police formations for effective crowd control and security measures.
He emphasized that collaboration with the police and the National Emergency Management Agency (NEMA), is crucial to safeguarding lives and ensuring that such efforts to assist those in need do not inadvertently lead to further distress.
Furthermore, the Minister appealed to politicians and other stakeholders to refrain from politicizing the unfortunate incidents, stressing that those tragic events are in no way connected to President Bola Ahmed Tinubu’s administration’s economic reforms.
“It is worth noting that similar unfortunate occurrences have been recorded in the past, before the current administration, as such, making any attempt to link these tragedies to the President’s reforms is unfounded and disingenuous,” he said.
Idris said the reforms, while repositioning the Nigerian economy for sustainable growth, are designed to uplift the lives of all Nigerians, particularly the vulnerable without causing distress.
The Minister called for a collective sense of responsibility and urged citizens to unite and ensure that the Yuletide season is marked by peace, goodwill, and joy.

CUBA: MARCH OF THE COMBATING PEOPLE CONFIRMS THE UNITY OF THE CUBAN PEOPLE AGAINST THE BLOCKADE AND THE REMOVAL FROM THE LIST OF COUNTRIES THAT ALLEGEDLY SPONSOR TERRORISM.
CUBA: MARCH OF THE COMBATING PEOPLE CONFIRMS THE UNITY OF THE CUBAN PEOPLE AGAINST THE BLOCKADE AND THE REMOVAL FROM THE LIST OF COUNTRIES THAT ALLEGEDLY SPONSOR TERRORISM.

On December 20, at the end of the plenary session of the National Assembly of People’s Power of the Republic of Cuba (ANPP), a popular march took place in front of the United States Embassy in Havana, with the aim of firmly and forcefully denouncing the atrocities caused within the country by the unjust and criminal blockade of the United States of America and the permanence of Cuba on the illegitimate list of countries that supposedly sponsor terrorism.
The Havana seafront, faithful scene of Cuban struggles and just causes, was, once again, witness to the humane and revolutionary claim of a resilient and combative people.
The March of the Combatant People, the name given by Commander-in-Chief Fidel Castro Ruz to the many popular complaints made by the Cuban people against the unjust measures adopted by the United States government against the Island for more than 62 years, was led by the President of the Republic Miguel Díaz Canel Bermúdez and the Army General and leader of the Cuban Revolution Raúl Castro Ruz.
On October 31, the United Nations General Assembly adopted for the 32nd time, with an overwhelming majority, the resolution in which it calls on the United States to end the prolonged economic, commercial and financial blockade against Cuba. The resolution, supported by 187 States, including Nigeria, reaffirmed once again the total support of the international community for the just struggle of the Cuban people and government.
During the march, the Cuban president said: “We do not profess the slightest feeling of hatred against the American people. To the noble citizens of that country, we offer our full respect, and our hand is always extended to strengthen the bonds of brotherhood between the two peoples. That is the same hand that we have extended to all US governments since the triumph of the revolution until today, always in terms of a serious, respectful relationship and on equal terms, but if the US persists in its efforts to undermine our sovereignty, our independence, our socialism, they will only find rebellion and intransigence.”
He also reiterated: “This will be a march, yes, very anti-imperialist. Against American imperialism and its attempt to impose itself in Cuba by force or seduction, we will march now and always.”
CUBA: MARCH OF THE COMBATING PEOPLE CONFIRMS THE UNITY OF THE CUBAN PEOPLE AGAINST THE BLOCKADE AND THE REMOVAL FROM THE LIST OF COUNTRIES THAT ALLEGEDLY SPONSOR TERRORISM.
