According to the overall plan of the third line construction of the state, with the approval of the former first Ministry of machinery industry, Wafangdian Bearing Factory was built. From the end of 1964 to the beginning of 1965, the first Ministry of machinery sent personnel to Ningxia for investigation twice, and established the northwest bearing factory in Dashuigou, Pingluo County, Ningxia, which met the requirements of “relying on mountains, concealing and dispersing” combat readiness. In April 1996, the original northwest bearing factory established Northwest Bearing Co., Ltd., the first listed company in China’s bearing industry, through joint-stock transformation. In 47 years of development and construction, the West axis has experienced three stages.

Stage one

From 1965 to 1981, it was the stage of building factories in mountainous areas. Thousands of builders from Wafangdian Bearing Factory and all over the country have been working hard in Dashuigou to build roads, bridges and factories. After several years of hard work, it was put into production in 1970. In the next few years, the factory developed slightly, but due to its remote location, inconvenient transportation, the production lingered. In the early 1980s, the production jumped into a low ebb and became a big loss maker in Ningxia at that time.

The second stage

From 1982 to 1992, it was the stage of adjustment and transformation. That is to say, the relocation from Dashuigou in Helan Mountain to Yinchuan city will be carried out. With the concern and support of the party and the government, the company merged the original Yinchuan bearing factory, opened a new factory in the new urban area of Yinchuan City, and started its second business. In 1986, the main production plants, such as material preparation, forging, heat treatment, lathe workers, medium-sized and large-scale ones, were moved to Yinchuan. Later, all the production plants, auxiliary production plants and thousands of employees’ families were gradually moved to the new plant area. Without asking for a penny from the state, without stopping production for a day, and with very hard production and life, it took 10 years to build infrastructure, move, produce, transform and develop at the same time. At the end of 1992, it successfully completed the historical task of adjustment and relocation. People of West axis composed a song of entrepreneurship and victory with wisdom and heart blood.

The third stage

Since 1993, it is a stage of rapid development. In 1996, Northwest Bearing Co., Ltd. was founded. From 2002 to 2006, we put forward and achieved the goal of “three years to get rid of poverty, five years to double and leap forward development”. Then we put forward the goal of “three to five years to achieve a total sales of 1 billion yuan and 10 years to enter the top five industries”. In 2007, after the assets reorganization, China Great Wall Asset management company obtained 81.92 million shares of West axis held by West axis group, accounting for 37.78% of the total share capital, becoming the largest shareholder of West axis. “NXZ” trademark is recognized as “China’s well-known trademark”. In 2008, the company won the honorary titles of “national export commodity exemption qualification”, “autonomous region’s oil R & D and innovation team”, and passed the “national high-tech enterprise certification”.
