Wafangdian Bearing Co., Ltd.(ZWZ)

The outer diameter of the bearing is directly in contact with the intermediate roller, and it is subjected to high rolling force while rotating. The outer ring thickness is increased in design, and the fully soft core has good impact resistance; the surface hardened layer is deep enough to increase the number of outer diameter repairs while ensuring rigidity; high quality material structure ensures high fatigue resistance. The difference in mounting wall thickness of all the  bearings used on one shaft is not more than 0.005 mm, and the difference in mounting wall thickness of adjacent bearings is not more than 0.002 mm.

ZWZ Group, the backbone of China’s bearing industry, has always been leading the industry trends. ZWZ has firstly developed bearings for heavy truck, railway wagon,railway coach, railway locomotive, metallurgical mill, machine tool spindle, automotive wheel and wind turbine.

Through over half a century with winds and rains, starting as a company that produced bearing parts and and bearing equipment, ZWZ has gradually developed into a modern enterprise which mainly produces bearings for major technical equipment and became the biggest manufacturing and sales base of bearings in China. 

ZWZ has made great contribution to development of national bearing industry and was awarded as National Service Enterprise by society and was called “China’s bearing hometown”by Party and state leaders.
