Shanghai Zhenshuo Co., Ltd. is a comprehensive company specializing in the bearing production, sales and technical services. We can meet your demands from bearing components to finished bearing. The headquarters is located in the international metropolis Shanghai, China, and the production base is in Zhejiang Province.
Starting as a trading company, ZHENSHUO has now become a business entity gradually by participating in bearings manufacture. In 2013, our production base (Xinchang Puyou Electromechanical Technology Co., Ltd.) for inner and outer rings of bearings was established. With an area of 26,000 square meters, this production base is large enough to complete large scale production for various types of inner and outer rings, such as ball bearing rings, taper roller bearing rings, and cylindrical roller bearing rings, non-standard bearing rings, as well as customized irregular shaped rings. Our production capacity can reach 15 million sets per month.
ZHENSHUO bearing rings are available with inner diameter ranging from 10mm-150mm, which can be manufactured from steel tube or forging steel bar depending on the required size. When processing rings with inner diameter ranging from 10mm-50mm, steel tubes are used as the raw material. The production process involves tube cutting, centerless and end-face grinding, turning, washing and cleaning, heat treatment; bearing rings with inner diameter ranging from 55mm-150mm are made using forging steel bar, which undergo forging, annealing, blasting cleaning, turning, heat treatment. Heat treatment is a crucial step in the process that gives our bearing rings their characteristics of outstanding stability and hardness. Our company is equipped with advanced production lines for the automatic heat treatment and cutting-edge furnaces. This enables us to provide bearing manufacturers with one-stop bearing rings with high quality and performance.
