China Liaocheng First Machinery Manufacturer Earns This Honor! Halin Group Bearing Products Now Supporting Major China Equipment

On March 13th, the Shandong Provincial Department of Science and Technology announced the list of enterprises nominated for support under the 2025 Shandong Provincial Small and Medium-sized Enterprises Innovation Competition Action Plan. HLB was among those listed. The public announcement period ended on March 19th, marking the first machinery manufacturing enterprise in Liaocheng to receive this honor, fully demonstrating the company's strong capabilities in technological innovation.

It is understood that after the Spring Festival, HLB's high-precision thin-walled self-lubricating spherical bearings for the aerospace field passed the scientific and technological achievement evaluation by the expert group of the Shandong Provincial Department of Science and Technology. Simultaneously, the company's independently developed "a self-lubricating spherical bearing outer ring gasket press-fitting device" was also granted a national invention patent. Combined with this latest inclusion on the list, it can be described as a "triple celebration." The high-precision thin-walled self-lubricating spherical bearings for the aerospace field developed and produced by Shandong HLB have already been successfully supplied to a well-known domestic aerospace company. According to Ma Jiye, General Manager of the company, this product relies on three core innovations: materials, structure, and process. Its self-lubricating properties, bonding strength, and resistance to fretting wear have been greatly improved. It has been successfully applied in the aerospace field, providing key supporting components for domestically produced major equipment. The high-precision thin-walled self-lubricating spherical plain bearing for the aerospace field is a benchmark achievement of Harbin Lin Group in the high-end bearing segment. The newly authorized invention patent effectively solves the industry problem of low precision and poor uniformity in the press-fitting of thin-walled bearing gaskets, further improving product production efficiency and quality stability. The authoritative recognition of scientific and technological achievements and the implementation of core patents demonstrate Harbin Lin Group's core innovative strength in the high-end bearing field, and also add new momentum to the independent control of key components in the equipment manufacturing industry.

The continuous emergence of scientific and technological achievements stems from the company's decades-long commitment to technological innovation. As a national-level specialized and innovative "little giant" enterprise, Harbin Lin Group directly confronted the "bottleneck" problem of foreign monopoly on PTFE braided fabric, the core raw material for self-lubricating bearings. It assembled a professional R&D team to focus on key challenges, successfully achieving the domestic mass production of maintenance-free self-lubricating bearings, filling a gap in the domestic market and exporting them to Europe and America. Relying on deep industry-university-research integration with institutions such as the Luoyang Bearing Research Institute and Henan University of Science and Technology, and leveraging the local "Science and Technology Vice President" policy benefits, the company has accumulated 10 authorized invention patents and 37 utility model patents, developing more than 60 new products, including automotive bearings and marine propulsion bearings. Many of these products have reached international advanced levels and have been selected for the "Good Products of Shandong" and "Shandong ManufacturingQilu Fine Products" lists. In 2025, HLB not only won numerous honors, including the second prize in the Shandong Provincial Equipment Manufacturing Technology Innovation Award and being named an outstanding enterprise in the Shandong division of the China Innovation and Entrepreneurship Competition, but also successfully retained its position as a standing director unit of the 10th China Bearing Industry Association and a member unit of the National Rolling Bearing Standardization Technical Committee, demonstrating the industry's high recognition of its technological strength.

Currently, the company's project to produce 5 million sets of high-end precision spherical plain bearings annually is under construction. The first phase of the plant is already in operation, and the second phase is being accelerated. In the future, the company will further expand into emerging fields such as new energy vehicles, marine engineering equipment, and rail transportation, consolidate its advantages in the European and American markets, and deeply integrate into the global mainstream supply chain.
