Linqing Sitong Precision Bearing Manufacturing Co., Ltd. is located adjacent to Yandian Town in Linqing City, a hub for bearing production and distribution. The factory covers an area of more than 8,000 square meters and has an annual production capacity of 850,000 sets of P5 and P6 grade self-aligning roller bearings (CA, CC, MA, MB, EM, SET, and E1 types). The company has also established a subsidiary, WGYZ, in the Zhuhua Industrial Park in Wafangdian City, Liaoning Province.

The company has long been committed to “reducing rolling bearing friction” and has collaborated closely with research institutions such as the Luoyang Bearing Research Institute and the Ningxia Metallurgical Machinery Research Institute for over a decade. This collaboration has resulted in products characterized by “innovative design and manufacturing processes, high dimensional accuracy, high rotational precision, high load-carrying capacity, and long-term stable and reliable performance.” The independently developed SET-type self-aligning roller bearings have gained favor among customers for their smooth operation, low noise, high rotational speed, high load capacity, and long service life, and are known as the “specialized type for wind turbines.”

The company closely leverages the advantages of the local bearing industry cluster, actively implements a talent strategy, and consistently adheres to the management and development goals of “aligning quality and philosophy with both domestic and international standards” and building “a corporate environment characterized by high well-being and a strong sense of security.”

In addition to meeting the supply needs of domestic enterprises in the metallurgy, coal mining, papermaking, and petroleum machinery manufacturing sectors—such as TISCO, Sany Heavy Industry, Guizhou Mining Group, and Zibo Fan Factory—our products are also exported to numerous countries and regions, including Germany, Russia, Turkey, the United Arab Emirates, and India. We have established more than 160 sales outlets in major and medium-sized cities across China. “Perseverance wears away even stone; success comes from deep accumulation; with flexibility and agility, we span the globe.” We warmly welcome business partners from home and abroad to visit our company to discuss cooperation and join us in this grand endeavor!
