Northwest Bearing

Northwest Bearing Co., Ltd. (西北轴承有限公司), known by the NXZ trademark, is a Chinese industrial bearing manufacturer based in Yinchuan, Ningxia Hui Autonomous Region. The company traces its origins to Northwest Bearing Factory, established in 1965 as part of China’s Third Front construction. Its current official company profile describes it as a wholly owned enterprise directly managed by Ningxia State-owned Capital Operation Group Co., Ltd. The supplied evidence does not identify an individual founder. The company makes and sells rolling bearings for equipment manufacturers and other industrial customers. Its catalogue includes deep-groove ball bearings, cylindrical roller bearings, spherical roller bearings, tapered roller bearings, angular-contact ball bearings, thrust roller bearings and spherical plain bearings. Featured products include insulated bearings, four-row cylindrical roller bearings, rolling-mill backup bearings, long cylindrical roller bearings, axle tapered roller bearings, subway bearings and petroleum machinery bearings. The company says its bearings serve petroleum machinery, metallurgy and rolling mills, heavy vehicles, rail transit, construction and mining machinery, cement machinery, water conservancy projects, motors and agricultural machinery. Northwest Bearing reports that it can make bearings with outside diameters from 40 mm to 3,500 mm, covering more than 8,000 product specifications, and can produce non-standard or special-structure bearings to customer requirements. Its homepage also describes production of more than 5,000 types, so the supplied company materials use different catalogue-count formulations. The company identifies petroleum machinery bearings as a particular area of research and manufacturing capability. It says it holds independent import and export rights and exports bearing products to more than 50 countries and regions. The company presents its engineering and development capabilities as an important part of its offering. Its facilities include a nationally recognized enterprise technology center, a national-local joint engineering laboratory and a postdoctoral research workstation. It reports developing bearing CAD/CAPP/PLM design software, integrated product-data management systems and three-dimensional dynamic simulation and optimization systems. Its NXZ trademark has been recognized as a China Well-known Trademark, and the company says more than 100 of its products have filled gaps in domestic supply. As of the supplied official website material, it remains an active, state-owned-group-managed manufacturer and is publicly promoting a “second venture” initiative focused on revitalizing and transforming the business.

Northwest Bearing’s institutional history begins with Northwest Bearing Factory, which the company says was established in 1965. The factory was founded during the period of China’s Third Front construction, and the company identifies itself as one of the major bearing producers in western China. The supplied official profile does not name the factory’s individual founders or provide a detailed account of its early organizational changes, so those details cannot be established here. Over the decades, the enterprise developed into a manufacturer serving a broad range of industrial equipment applications. Its official account says its bearings are used in petroleum machinery, metallurgical and rolling-mill equipment, heavy vehicles, rail transit, engineering and mining machinery, cement equipment and water conservancy projects, among other sectors. It describes the company as a petroleum machinery bearing research and production base and highlights the development of drilling bearings. The company reports that its self-developed petroleum drilling bearing 30228/630Q received a national quality gold award. It also states that more than 100 of its products filled gaps in domestic supply, and that it received a number of quality, technical-improvement and enterprise-management honors. The company’s profile emphasizes technical infrastructure alongside manufacturing. It identifies a nationally recognized enterprise technology center, a national-local joint engineering laboratory and a postdoctoral research workstation among its research platforms. It also reports developing bearing CAD/CAPP/PLM design software, an integrated product-data management system and three-dimensional dynamic simulation and optimization systems. These capabilities support a catalogue spanning several principal rolling-bearing categories as well as specialized products, large-diameter bearings and customer-requested non-standard designs. The company’s present corporate form is described on its official website as Northwest Bearing Co., Ltd., a wholly owned enterprise directly managed by Ningxia State-owned Capital Operation Group Co., Ltd. Its production site and office address are in the high-end bearing industrial base on Liupanshan Road in Xixia District, Yinchuan. The company says it holds independent import and export rights and exports products to more than 50 countries and regions. Its NXZ trademark has been recognized as a China Well-known Trademark. Company materials give different catalogue counts: the homepage refers to more than 5,000 types, while the company profile states more than 8,000 specifications; both describe bearings with outside diameters from 40 mm to 3,500 mm. Recent supplied homepage news shows the company pursuing a “second venture” program. In March 2026 it announced the initiative’s core tasks and strategic direction. In April it participated in a cross-regional research and cooperation activity in Luoyang, reported in May, and in June the homepage reported a second regional progress meeting on the initiative. These items point to a current emphasis on organizational revitalization, technical cooperation and business transformation, but the supplied evidence does not specify final outcomes or financial targets.
