On June 19, 2025, Changsheng Bearing (stock code: 300718) released a record of investor relations activities, disclosing the company's acceptance of 18 investment institutions' surveys at the Zhongtai Securities and Northeast Securities strategy meetings. Participating institutions cover multiple financial fields such as fund companies, securities companies, and insurance companies. The meeting focused on topics such as the company's main business, product features, market distribution, and key customers, showing the company's technical accumulation and industrial layout in the field of self-lubricating bearings.

Covering multiple industrial scenarios, automobiles and engineering machinery account for a prominent proportion

Changsheng Bearing mainly focuses on the research and development, production and sales of self-lubricating bearings and related high-performance polymer materials. Its product types are rich, including metal-plastic composite bearings, bimetallic sliding bearings, engineering plastic bearings and other forms, and widely serve multiple industries such as automobiles, engineering machinery, robots, energy equipment, agricultural machinery, and port machinery.

From the perspective of revenue structure, in 2024, the company's revenue from the two industries of automobiles and engineering machinery accounted for about 80% of the total revenue, and the remaining industries were relatively scattered, accounting for about 20% in total.

Cooperation in the field of construction machinery is stable, and market demand is gradually recovering

In the field of construction machinery, the company's products are used in key moving parts such as cylinders, connecting rods, supporting wheels, guide wheels and other parts of equipment such as excavators, pavers, forklifts, etc. Major customers include internationally renowned companies Caterpillar, domestic leader Sany Heavy Industry and hydraulic system supplier Hengli Hydraulics.

According to data from the China Construction Machinery Industry Association, more than 100,000 excavators were sold nationwide in the first five months of 2025, a year-on-year increase of 17.4%, of which the domestic market grew faster, reaching 25.7%. As the industry recovery trend emerges, the company said it will actively seize market opportunities and improve business performance.

The automotive sector continues to exert its strength, and customer resources are high-quality and stable

In the automotive field, the company's products are mainly used in seat adjustment, steering systems, shock absorbers and other parts, while some lead screw products can be used for braking, parking and transmission systems. The customer base is mainly composed of world-renowned Tier 1 and Tier 2 parts suppliers, such as Faurecia, Adient, Tenneco, Bosch and Aisin.

The company emphasizes that its products have the advantages of diversity, high performance and cost competitiveness, which can effectively reduce the cost of use while meeting customer needs. In the future, it will continue to promote product iteration, expand application scenarios, and strengthen customized service capabilities to further consolidate its position in the automotive market.

Self-lubricating bearings have excellent performance and adapt to complex working conditions

Self-lubricating bearings are a type of sliding bearings. Different from traditional rolling bearings, they are characterized by embedded lubricants or special structural designs in the material to achieve long-term operation without external refueling. Suitable for high temperature, low temperature, corrosive environment, vacuum and other difficult to maintain occasions.

Changsheng Bearing's products have multiple advantages such as lightweight, maintenance-free, low noise, high load capacity, corrosion resistance, and environmental protection. They can meet the use needs under various extreme working conditions, so they are widely recognized by downstream customers.

The sales system is perfect and focuses on customer value creation

The company has a dedicated sales subsidiary responsible for market development and technical support, dedicated to accurately identifying customer needs and providing integrated solutions from material research and development to product design. In the service process, we not only focus on the functionality of the product, but also emphasize the goal of reducing costs and increasing efficiency for customers.

In addition, another subsidiary focuses on the production and promotion of non-metallic self-lubricating bearings, further strengthening the company's comprehensive competitiveness in this segment.

Explore new tracks for robots and give full play to the advantages of technological differentiation

In the field of robots, the company is exploring the application of self-lubricating bearings in joint modules, actuators and dexterous hand parts. Compared with traditional rolling bearings, self-lubricating bearings have simpler structures, lighter weight, lower costs, and good impact resistance and maintenance-free characteristics.

Especially when the robot encounters an accidental collision or overload, the self-lubricating bearing can better protect the joint structure with its higher load-bearing capacity, extend the service life, and help improve the reliability and economy of the whole machine.
