BUYER QUICK VIEW
Decide what to inspect next.
The strongest public signals and the most important open question are grouped here so a buyer can qualify this lead without reading the full page first.
Confirm who they are before judging what they can make.
Domestic AI models help discover and organize public leads. Official sources must still confirm the legal name, address, brand ownership and manufacturing entity.
ENTITY TYPECorporate group · multiple manufacturing sites and subsidiariesGroup identity is supported by official sources; confirm the actual manufacturing subsidiary and plant for each bearing
Wafangdian Bearing Group traces its origins to 1938 and describes itself as the birthplace of China's bearing industry. The group publishes a network of nine manufacturing bases, ten business divisions and 26 wholly owned or controlled subsidiaries.
Under the ZWZ and KRW brands, the company says it manufactures more than 20,000 bearing specifications across ten major categories, from 20 mm bore products to bearings with an outside diameter of 16 metres.
Published application areas include industrial equipment, rail transport, automotive vehicles, wind energy and specialised fields. Buyers should qualify the precise plant and product family, and request current drawings, material records, heat-treatment controls, inspection data and application approvals.
