Shandong YJXG Bearing Manufacturing Co., Ltd. specializes in producing spherical roller bearings, and we survive for high quality . In July 2009, YJXG passed ISO9001:2008 quality management system certification and ISO14001:2004 environmental management system certification. The company adopts CNC machine production lines and meantime, we set up perfect quality control system, which can follow up the whole procedure. In early 2009, the company set up a measurement center with complete test equipment including metallographic detection, outline detector, roundness device, roughness tester etc. Through this, we can control the production process strictly, and ensure the stability of quality and consistency of the bearing. In the second half of 2011, the company will introduce life testing equipment, which can study and analyze the performance of bearing used in different environment conditions. This will help us meet the needs of customers. At present, our products are widely used in mining, oil field, steel mills and other fields. Especially, bearing for blowers (roots blowers, centrifugal blowers) and steelworks got high raise from our customers. Guided by our principle "Always innovation and supplying perfect bearing", YJXG hopes to cooperate with friends home and abroad and enjoy a wonderful future.
