At the just concluded BMW exhibition, Tongli slewing bearings (hereinafter referred to as "Tongli") once again became the focus of industry attention with outstanding products and cutting-edge technology. With a brand history of 21 years, Tongli has led the way in leapfrog development and firmly expressed its determination to increase research and development investment and continue to lead industry technology.
Technological accumulation forges product strength
During the exhibition, Tongli showcased a variety of high-tech products, including the highly acclaimed elliptical raceway double volleyball type slewing bearing, the tilting bearing that breaks the technological blockade, the efficient and stable slewing drive, and the lightweight slewing bearing that serves industries such as intelligent warehousing equipment, forklift attachments, medical equipment, and three-dimensional garages. This showcased Tongli's fruitful achievements in the field of diversified multi industry supporting solutions while deeply cultivating in the construction machinery industry.
According to Hou Shuhao, General Manager of Ma'anshan Tongli Rotary Bearing Co., Ltd., the elliptical raceway double volleyball rotary bearing has been widely used in heavy-duty equipment such as mining excavators, crawler cranes, large tonnage truck cranes, and port machinery, with a cumulative application case of over 13000. This product has been deeply used in the core applications of many large machine manufacturing enterprises at home and abroad, including XCMG, Sany, Liugong, Lingong, Shanhe Intelligent, etc. In addition, the pace of market application has significantly accelerated in 2024, achieving significant growth during the same period. In the overall market environment that is not optimistic, this product has grown against the trend and stood out, thanks not only to Tongli's profound accumulation in the field of technological innovation, but also to its ability to accurately grasp market demand and deeply explore core competitiveness.
From the initial conceptual design to physical implementation and market sales, to undertaking national key research and development projects, tilting support remains a shining star at the exhibition. It is reported that the product was independently developed by Tongli and made its debut at the BMW exhibition in 2014, breaking the long-standing technological blockade between Germany and Japan and achieving localization. Tilting support can quickly achieve ± 10 ° leveling, and can be widely used in equipment operating under complex working conditions such as cloud ladders, fire trucks, and military industries. Compared with traditional methods of leveling, tilting supports have great advantages in complex working environments and high timeliness applications such as firefighting and rescue.
During the technological breakthrough process of "ten years of grinding a sword", Tongli not only broke through technical barriers, but also achieved internal structural optimization and multiple independent innovations, making the product stand at the forefront of the industry. Nowadays, it has not only become a benchmark for industry innovation, but also contributed to the development of China's high-end equipment manufacturing industry.
Innovation never stops, forging internationalization
Facing the uncertainty of the external environment and market, Tongli always focuses on the accumulation of soft power. Many years ago, Tongli collaborated with mechanics teams from Anhui University of Technology and Hefei University of Technology to propose a new design concept based on finite element analysis and calculations. In 2023, seven key parameters that affect the load-bearing capacity of ball bearings were further revealed - raceway surface hardness, quenching layer depth, substrate hardness, clearance, double raceway clearance difference, curvature ratio, and contact angle. Theoretically, the load-bearing capacity of the rotary bearing was doubled.
Adhering to the concept of "technology runs through the entire value chain", we strive to balance technology and research and development, and comprehensively enhance the overall performance of our products. The company has collaborated with machine tool manufacturers to jointly develop specialized and efficient intelligent machine tools, and independently developed equipment such as assembly machines and flipping machines, further optimizing the process system. These innovations have doubled the processing efficiency and significantly improved the processing quality. At the same time, the heat treatment team has successfully overcome natural defects such as poor material adaptability, and completed multiple key technological breakthroughs in the "scheme to improve the depth of the hardened layer of the large raceway rotary bearing raceway", achieving a leading technical level in China.
At present, the key technical indicators of Tongli's ball type slewing bearing are scientific, the process is reliable, and the rated static capacity per kilogram has reached 20KN. As the first drafting unit of industry standards, Tongli participated in the revision of three sets of industry standards JBT10837, 10838, and 10839-2023, and gradually established a strong advantage in competing with top global brands.
The next goal of Tongli is internationalization. As they envision for the future: "The fourth seven years of Tongli are seven years of international development." Carrying the heavy load of world engineering machinery giants and the trust of industry "hidden champions," Tongli is worth looking forward to in product delivery and service.
Despite the successful conclusion of the BMW exhibition, Tongli understands that behind every display and innovation, there is a persistent pursuit of endless technological exploration and a firm commitment to excellent quality. With an outstanding product matrix and cutting-edge innovative technology, Tongli has consolidated its position as a industry leader in the field of construction machinery.
In the future, Tongli will continue to deeply cultivate technology, continuously launch high-performance products to meet the needs of the market and customers, while continuously improving product quality and technological level, setting new benchmarks for the industry, and leading the trend of industry development.
