ZWZ

ZWZ is the principal bearing brand of Wafangdian Bearing Group Co., Ltd. (often shortened to Wazhou Group), a Chinese industrial group headquartered in Wafangdian, Dalian, Liaoning. The group describes itself as the birthplace of China's bearing industry, with origins dating to 1938. It operates nine major manufacturing bases in China and abroad, ten business divisions, and 26 wholly owned or controlled subsidiaries. Alongside ZWZ, the group also owns the KRW bearing brand. ZWZ produces a very broad range of bearings: the company states it can manufacture ten major categories in more than 20,000 specifications, with bore diameters from 20 mm to an outer diameter of 16 meters, in various precision grades. These products serve industrial equipment, rail transit, automotive vehicles, wind power and new energy, and special-purpose fields. The group positions itself as a one-stop bearing solutions provider, offering fast and reliable service and adaptive service models to customers. Technology and quality infrastructure are central to the brand. Wazhou Group hosts a National Large Bearing Engineering Technology Research Center — approved by China's Ministry of Science and Technology in 2009 and formally named after passing acceptance in November 2013 — described as the only state-approved bearing engineering center in China's bearing industry. It also operates a national-level enterprise technology center and a bearing testing center. Overseas, it runs a European R&D center in Schweinfurt, Bavaria, Germany, and a US R&D center in Detroit, Michigan, established in March 2015, focused on automotive bearings. A Shanghai R&D center was set up in 2022 to build a high-end product platform. ZWZ's products have been used in landmark applications, including the first bearing set for an 11 MW semi-direct-drive offshore wind turbine — described as the world's largest at the time — and the first 4.5 MW pitch bearing set for a mainstream onshore model of a well-known European wind turbine manufacturer. The group employs more than 6,500 people and offers more than 20,000 product types. Its stated mission is to focus on customer needs and provide internationally competitive bearing solutions, with a vision to become a world-class bearing industry group.

Wafangdian Bearing Group, the company behind the ZWZ brand, traces its origins to 1938, when it was founded in Wafangdian, Dalian, Liaoning. The group describes itself as the birthplace of China's bearing industry, a claim rooted in its long history as one of the country's earliest and largest bearing manufacturers. Over the decades, it grew into a comprehensive industrial group with multiple manufacturing bases, business divisions, and subsidiaries. A major institutional milestone came in 2009, when China's Ministry of Science and Technology approved the establishment of the National Large Bearing Engineering Technology Research Center at Wazhou Group. The center passed acceptance by the Ministry in November 2013 and was formally named, becoming — according to the company — the only state-approved bearing engineering center in China's bearing industry. This reinforced the group's role as a national technology platform for bearing research, materials, lubrication, simulation, and testing. Internationalization accelerated in the 2010s. In March 2015, Wazhou Group established its US R&D center in Detroit, Michigan, focused on the American automotive bearing market and described as the group's first overseas testing center and a world-class automotive bearing testing facility. The group also set up a European R&D center in the Schweinfurt industrial area of Bavaria, Germany, to support its "high-end and international" strategy, optimize overseas market layout, and build a European service network. In 2022, Wazhou Group founded the Shanghai R&D Center to create a high-end product platform, drawing on talent and technology resources in the Yangtze River Delta region and leveraging the group's existing national engineering center and overseas R&D centers. The group has also pursued organizational reforms, including a "self-adaptive organization" reform and the building of a group-level management and operations system, and has entered the "14th Five-Year Plan" development phase. Throughout its history, ZWZ products have been used in landmark applications such as the first bearing set for an 11 MW semi-direct-drive offshore wind turbine and the first 4.5 MW pitch bearing set for a mainstream onshore model of a well-known European wind turbine manufacturer.
