The Factory

  Advantage Ball Bearing Manufacturing Base is located in Cixi, the gathering place of China's bearing industry. The enterprise consists of two production plants, one focusing on the production of general grade ball bearings, and the other dedicated to the manufacture of EMQ high-quality bearings that meet the stable Z3V3 standard. The factory spares no effort to introduce the world's leading bearing manufacturing technology and equipment, and widely adopts CNC automated production lines, which is now among the most advanced equipment and technology in China's bearing manufacturing industry. The ball bearing manufacturing division of Granville offers a comprehensive range of radial deep groove ball bearings covering open, shielded, sealed, chrome steel and stainless steel materials to meet the needs of different customers.

 Manufacturing Process
Granville, as a manufacturer of high-quality products, guarantees compliance with the highest standards relative to the use of the best steel quality in the production process, the highest standards in the design of contact surfaces, as well as the most efficient packing and lubrication of parts.

From material coming, quality control through all processes except internal test, goods to third party inspection if required. After the center of inspection and experiment is founded, effective methods of inspecting all kinds of row materials are mastered and then the reliability of bearings is ensured. 

One of our main objectives is the continued improvement in the quality of our products and processes, in pursuit of which we obtained ISO certification 9001:2008 and TS16949.
