ZYS precision angular contact ball bearing is divided into four series: high-speed angular contact bearing (Standard Series), ultra-high-speed angular contact ball bearing, high-speed sealed angular contact ball bearing and high-speed electric spindle bearing.

Generally, the inner and outer rings of rolling bearings are made of high carbon chromium bearing steel, but in some applications, such as in places requiring ultra-high speed, wear resistance, low temperature rise, long life and high reliability, the performance of steel bearings can not meet the requirements of working conditions, so it is necessary to select bearing materials with better performance. Among them, silicon nitride ceramic is considered to be the most ideal rolling bearing material instead of bearing steel. ZYS also provides widely used hybrid ceramic angular contact ball bearings for high-speed precision machine tool spindles and other high-speed precision machine spindles, that is, the inner and outer rings of the bearings are made of high-quality bearing steel, while the rolling elements are made of silicon nitride ceramic.

Compared with the angular contact ball bearing made of the same structure, size and standard steel, the hybrid ceramic angular contact ball bearing has the advantages of high speed performance, high rigidity, low friction heating and long service life.

ZYS angular contact ball bearings can bear radial load and one direction axial load. When the bearing withstands radial loads, axial force will be generated on inner ring. Therefore, the single-row angular contact ball bearings are often used with other bearings which can withstand axial load in the opposite direction. That is, angular contact ball bearings are commonly used in pair, or in groups with three, four and even five bearings.

Contact angles
The contact angles of ZYS angular contact ball bearings for machine tool are 15° and 25°. The bearing with 15° contact angle is used when the high speed and light axial load are needed, while the 25° contact angle bearing should be adopted on the contrary.

Four dimension series
The precision angular contact ball bearings for spindles have four dimension series, 718, 719, 70 and 72. With the same inner diameter, the outer diameter and the width of 718, 719, 70 and 72 increase in sequence.

Northwest Bearing Co., Ltd-NXZ China bearing manufacturer

Baota Industrial Co., Ltd. (formerly Northwest Bearing Co., Ltd.), located in Yinchuan City, the capital of Ningxia Hui Autonomous Region, was founded in 1965. In April 1996, Northwest Bearing Co., Ltd. was established, which is the first A-share listing in China’s bearing industry.

Baota Industrial Co., Ltd. (formerly Northwest Bearing Co., Ltd.) is based on the development position of the western part of the motherland, equipping China, and serving the world. It can produce outer diameters of 40 mm to 4000 mm in accordance with international standards, the latest national technical standards and special customer requirements. More than 6000 kinds of bearings. Products are widely used in petroleum machinery, metallurgical rolling mills, heavy-duty vehicles, construction machinery and mining machinery, rail transportation, military equipment, precision motors and other fields. Customers cover the country and are exported to more than 50 countries in Europe, the United States, Asia, and Africa. area.

The company formerly known as the northwest bearing factory, is a third-line enterprise, founded in 1965 in the depths of Helan Mountain. In 1982, it began to move to Yinchuan urban area. It took ten years to build a modern factory in the beautiful saishanghu City Yinchuan urban area. It has become one of the 520 large enterprises supported by the state, one of the top 100 enterprises in the national machinery industry, and one of the backbone enterprises in the national bearing industry. It is one of the largest professional bearing production enterprises in Western China. In 1996, it was restructured and listed, becoming the first listed company in China’s bearing industry. In 2006, NXZ brand of the company was recognized as a well-known trademark in China. In 2008, it obtained the national export exemption qualification. In 2011, Baota Petrochemical Group became the controlling shareholder of the company, established the grand blueprint of building the company into a production base of high-end bearings and a first-class brand enterprise in China by taking strengthening the bearing industry as the main line, aiming at strategic emerging industries and major equipment manufacturing industries, seizing the commanding heights of Science and technology and market.

Northwest Bearing Co., Ltd. is the first listed bearing manufacturer in China. After more than 30 years of development, Northwest Bearing Co., Ltd. has stepped into the ranks of China’s 100 largest mechanical industry enterprises and become one of the largest bearing production enterprises in China. Main production and sales of all kinds of rolling bearings, products are exported to more than 50 countries and regions. The company’s technology center is recognized as a national enterprise technology center, developing nearly 200 kinds of new products every year. In 2000, more than 100 kinds of new products have been developed to fill the domestic gap, and a large number of products have reached the advanced level of similar products abroad. The company has perfect quality system and reliable quality assurance ability. In 2003, it passed ISO9001:2000 quality system certification. It has won many honors, such as “May 1st” labor certificate, “national quality and benefit oriented advanced enterprise” and “national quality Wanlixing advanced enterprise”.

In 2008 and 2009, he successively undertook the R & D of many new technologies and products, such as key technological innovation projects, pilot production projects of key new products in the autonomous region, scientific and technological research projects in the autonomous region, capital projects for optimizing the import and export structure of electromechanical and high-tech products, and has applied for 6 patents. The bidirectional cylindrical roller thrust bearing of new structure, rotary table bearing and backing bearing of oil drilling rig have been awarded In December 2008, it passed the appraisal of scientific and technological achievements of the autonomous region. Through the implementation of the project, the scientific research level of the engineering and technical personnel of the company has been improved. Three people were selected into the “new century 313 talent project” of the autonomous region, one received special allowance from the government of the autonomous region, and two obtained the qualification of professor level senior engineer.

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”.
