HZ-20 high tin aluminum bearing Manufacturers

HZ-20 high tin aluminum has excellent fatigue strength and wear resistance

In the demanding world of mechanical engineering and automotive manufacturing, the performance and reliability of components under high stress and continuous operation are critical. Zhejiang Huazhou Technology Co., Ltd., a leading Chinese manufacturer of self-lubricating bearing solutions, has developed a groundbreaking product that meets these rigorous requirements — the HZ-20 High Tin Aluminum Bearing. Engineered for superior fatigue strength and exceptional wear resistance, the HZ-20 is rapidly becoming the go-to choice for high-performance applications across a wide range of industrial and automotive sectors.

Established in August 2010 and officially restructured into Zhejiang Huazhou Technology Co., Ltd. in 2019, the company has evolved into a large-scale, integrated enterprise specializing in the research and development, production, sales, and service of self-lubricating bearings. Located in Nanxun, a historic Jiangnan water town renowned for its craftsmanship and industrial innovation, Huazhou Technology operates a modern manufacturing facility spanning 30,000 square meters. Backed by a total investment of 100 million yuan, the factory is equipped with over 280 sets of specialized machinery, 100,000 precision molds, more than 150 skilled technical professionals, and 50 fully automated production lines. This advanced infrastructure enables the company to maintain strict quality control and deliver high-volume, high-consistency products to meet global demand.

At the core of Huazhou’s success is its commitment to technological excellence and customer satisfaction. Guided by the core values of “customer first, integrity management, continuous learning, and continuous improvement,” the company has built a reputation for reliability and innovation. Over the years, Huazhou has focused on enhancing product consistency through continuous R&D, exploring new materials, and expanding into emerging application fields. This dedication has led to the development of advanced bearing materials like the HZ-20 High Tin Aluminum alloy, which delivers outstanding performance in high-load and high-cycle environments.

The HZ-20 High Tin Aluminum Bearing is specifically designed for applications where fatigue resistance and wear performance are paramount. Constructed with a high-tin aluminum-silicon alloy layer bonded to a steel backing, this bimetal composite bearing offers exceptional mechanical strength and thermal conductivity. The high tin content (typically 6–20%) significantly enhances the bearing’s fatigue strength, allowing it to withstand repeated stress cycles without cracking or deformation — a crucial advantage in engines, compressors, and heavy-duty machinery.

One of the key advantages of the HZ-20 is its excellent fatigue strength. In internal combustion engines and other high-vibration systems, bearings are subjected to fluctuating loads that can lead to micro-cracking and eventual failure. The HZ-20’s advanced metallurgical structure provides superior resistance to fatigue, ensuring long-term durability even under extreme operating conditions. This makes it ideal for use in automotive crankshafts, connecting rods, and transmission systems, where reliability directly impacts safety and performance.

In addition to its fatigue resistance, the HZ-20 exhibits outstanding wear resistance. The aluminum-tin matrix is engineered to maintain a smooth, low-friction surface, while the inclusion of solid lubricants such as PTFE and graphite in the substrate further enhances self-lubricating properties. This reduces wear on both the bearing and the shaft, minimizing maintenance needs and extending equipment life. The bearing also performs reliably in boundary lubrication conditions, making it suitable for applications where oil supply may be intermittent or under high thermal stress.

Zhejiang Huazhou Technology ensures that every HZ-20 bearing is manufactured to the highest quality standards. From raw material selection to final inspection, the production process is closely monitored using advanced testing equipment, including fatigue testers, wear simulators, and metallographic analyzers. This rigorous quality control system ensures that each product meets international standards and performs consistently in real-world applications.

The company’s products are widely used across China’s machinery industries and have been adopted by major automotive manufacturers such as Geely and BYD, where performance and reliability are non-negotiable. In addition to domestic success, Huazhou Technology exports its high-quality bearings to 16 countries worldwide, including Russia, Malaysia, Tasmania, Iraq, and Romania. The HZ-20, in particular, has gained recognition in international markets for its compliance with global engineering standards and its ability to deliver reliable performance in diverse operating environments.

Looking to the future, Zhejiang Huazhou Technology remains committed to innovation and sustainable growth. The company continues to invest in R&D, exploring new alloy compositions, surface treatments, and smart monitoring technologies to further enhance bearing performance. With a strong foundation in engineering excellence and a customer-focused philosophy, Huazhou is well-positioned to lead the next generation of bearing technology.

In conclusion, the HZ-20 High Tin Aluminum Bearing is a testament to Zhejiang Huazhou Technology Co., Ltd.’s expertise in advanced materials and precision manufacturing. Its exceptional fatigue strength and wear resistance make it an ideal solution for high-performance applications in the automotive, industrial, and energy sectors. As global industries demand more durable and efficient components, the HZ-20 stands out as a reliable, high-quality choice — backed by a company dedicated to innovation, integrity, and continuous improvement.
