Blue Whale News, February 19 (Reporter Wang Jianwen)Yushu Technology’s robot exploded, and the share prices of industrial chain companies rose after hearing the news.

On February 19, the stock price of Changsheng Bearing (300718.SZ) opened low and went high, recording a daily limit. At the close, the company’s share price closed at 98.77 yuan/share, setting a new high since its listing in 2017, and its total market value also reached approximately 29.5 billion yuan.

As early as December 2024, Changsheng Bearing’s share price entered a rising range. Since December 24, 2024, the company’s share price has risen from 18.60 yuan/share to 98.77 yuan/share, with a cumulative increase of 431.02%.

Changsheng Bearing’s share price rise this round may be related to the recent popularity of four-legged robots and humanoid robots under Yushu Technology. On December 23, 2024, Yushu Technology released the latest video of the Unitree B2-W quadruped robot (robot dog). In the video, the Unitree B2-W quadruped robot continuously completed a series of difficult movements such as Thomas full spin, side somersaults, downhill crossing the river, and manned off-road, which aroused heated discussion among netizens.

By 2025, Yushu Technology will be out of the circle again. On the stage of this year’s CCTV Spring Festival Gala, Zhang Yimou’s dance “Seedling BOT” also sparked widespread discussion. During the program, more than a dozen humanoid robots dressed in cotton-padded jackets danced yangko and spun handkerchiefs. These humanoid robots are the H1 products of Yushu Technology.

The continuous heat impact has brought Yushu Technology to fire, and Yushu concept stocks in the secondary market are also fierce. As a supplier of self-lubricating bearings for Yushu Technology’s humanoid robot, Changsheng Bearings has also received popularity in the market. As the company’s share price rises, the family value of Sun Zhihua, the company’s actual controller, has also risen, exceeding 10 billion yuan compared with the end of 2024.

Relying on the soaring stock price of Yushu, the value of the real controller’s family has risen by more than 10 billion yuan.

Changsheng Bearing has been deeply involved in the self-lubricating bearing industry for many years. The company was established in 1995 and specializes in self-lubricating bearings, low-friction pair parts and other products. It was listed on the Shenzhen Stock Exchange in 2017.

As Yushu Technology exploded in the circle, Changsheng Bearing’s share price rose simultaneously. Since December 24, 2024, the company’s share price has risen from 18.60 yuan/share to 98.77 yuan/share, with a cumulative increase of 431.02%, and the total market value has also increased by nearly 24 billion yuan.

The market value of Changsheng Bearing has increased significantly, and the value of the Sun family, the actual controller of the company, has also increased. At present, the actual controller of the company is Sun Zhihua. As of the end of the third quarter of 2024, Sun Zhihua and his concerted actors Sun Weiqing, Chu Chenjian and Parkson Investment jointly hold 52.83% of the shares of the listed company. Among them, Sun Zhihua and Sun Weiqing are father and daughter, and Chu Chenjian is Sun Zhihua’s son-in-law. With this wave of stock price rises, the value of Sun’s family assets has exceeded 12.6 billion yuan.

In addition to the actual controller’s family, Changsheng Bearing’s one-vote stake in Dong Jiangao can also make a floating profit from this wave of market. As of the end of the third quarter of 2024, the top ten shareholders of Changsheng Bearing also include Lu Xiaolin, Vice Chairman of the Company, Cao Yinchao, Director, Wang Weijie, Chairman of the Board of Supervisors, Lu Zhongquan, Chief Engineer, and Zhou Jinxiang, former Secretary of the Board of Directors, with shareholding ratios of 4.47%, 2.91%, 1.86%, 1.53%, and 0.58%, respectively. The total floating profit exceeded 2.7 billion yuan.

In addition, in the third quarter of 2024, Xingquan Multi-dimensional Value Hybrid Fund, among the top ten shareholders of Changsheng Bearing, increased its position in the company’s stock, increasing its shareholding ratio from 0.89% to 1.01%, which also became the winner in this round of market.

In contrast to the above-mentioned shareholders, some shareholding funds also failed to stabilize their positions before this round of market. For example, the China-Europe Fund China Life Equitable Equity Fund entered the top ten shareholders of Changsheng Bearing as early as the third quarter of 2022. Its shareholding ratio at that time was 1.34%, and it increased to 1.98% by the end of 2023. However, since entering 2024, China-Europe Fund China Life Equilibrium Equity Fund has begun to reduce its shares in the company, and has withdrawn from the top ten shareholders of the company in the third quarter of that year.

It planned to raise 400 million yuan to expand production, and intensive institutional research was welcomed after the fixed increase plan was cancelled.

As a company established in 1995, Changsheng Bearing has been deeply involved in the self-lubricating bearing industry for many years and currently specializes in self-lubricating bearings, low-friction pair parts and other products. For a long time, the company’s products have been mainly used in traditional industrial fields such as construction machinery, automobiles, energy, port machinery, and agricultural machinery. Its customers include Caterpillar, Liebherr, Sany Heavy Industry, Hengli Hydraulic, etc.

Although Changsheng Bearing enjoys a capital feast through its cooperation with Yushu Technology, the company also announced that the products of the cooperation are mainly self-lubricating bearings used in robot joints, and such products account for a relatively low proportion of the main business income., less than 1%.

The 2024 semi-annual report shows that Changsheng Bearing achieved revenue of 195 million yuan from metal-plastic polymer self-lubricating rolled bearing products, accounting for 35% of the total revenue, making it the bulk of Changsheng Bearing’s revenue; bimetal boundary lubrication rolled bearings, metal-based self-lubricating bearings and other businesses achieved revenue of 94.96 million yuan, 85.02 million yuan, and 16.24 million yuan respectively, accounting for 17%, 15% and 3% of total revenue respectively.

From a fundamental perspective, Changsheng Bearing’s operating income has continued to grow in recent years, but its parent’s net profit has fluctuated. From 2021 to 2023, the company achieved operating income of 985 million yuan, 1.071 billion yuan, and 1.105 billion yuan; net profit attributable to the parent company was 155 million yuan, 102 million yuan, and 242 million yuan respectively.

In the first three quarters of 2024, Changsheng Bearing achieved operating income of 835 million yuan, a year-on-year increase of 1.95%; net profit attributable to the parent company was 169 million yuan, a year-on-year decrease of 5.29%. Based on the research reports of Guosheng Securities and Caixin Securities, the decline in the company’s performance is mainly due to the demand recovery period of downstream industries.

In this context, Changsheng Bearing has been planning to expand its business boundaries and try to enter more downstream industries. In 2022, wind power gearboxes will gradually be replaced by rolling, and the company also plans to seize this opportunity to expand its wind power business.

In the same year, Changsheng Bearing put out a fixed increase plan, planning to raise 446 million yuan to expand the project with an annual output of 167 million sets of self-lubricating bearings and 30,000 sets of ball screws, and an annual output of 14,000 sets of wind power self-lubricating bearing projects, etc.

However, the above-mentioned fixed increase plan has been slow to be implemented. As of November 2024, the company finally terminated this fixed increase. At that time, the company stated that the reason for the termination was changes in the company’s actual situation and the capital market and other environments.

Since then, as Changsheng Bearing’s share price has soared, the company has also welcomed intensive institutional research. In 2025 alone, the company has received six institutional surveys, including Xingyin Fund, Huatai Securities, Huaxia Fund, Ping An Fund, China Post Fund, Zheshang Securities, Orient Fortune, AVIC Trust, CITIC Securities, and Morgan Huaxin. Dozens of institutions participated in it.
