The special spraying process can form a coating with uniform thickness and extremely strong adhesion, and then further processing to make it immune to the influence of moisture and humidity.
Electrically Insulated bearings are mainly used in motor products. Its use depends on the power state of the motor. Normal grid power supply has no high-frequency voltage and current components. Generally, electrically insulated bearings are not used. Only high-voltage motors and large motors such as 400 or more are used.
But now the frequency conversion power supply, The power quality contains a lot of high-frequency components, causing the motor shaft current to increase, so should be considered in the specifications above 400, even the smallest specifications also consider the installation to use Electrically Insulated Bearings, such as electric motors, electric rail locomotives, and other main motors generally use about 100KW. Electrically insulated bearings must be used (or other insulation structures must be used to ensure that shaft current does not flow).
Electrically insulated bearings can avoid damage caused by electrical corrosion, so compared with ordinary bearings, they can ensure more reliable operation in motors. Compared with other insulation methods, such as shaft or housing insulation, it is more cost-effective and reliable. The dimensions and basic technical characteristics of insulated bearings are the same as those of non-insulated bearings, so they are 100% interchangeable.
According to the bearing structure, insulated bearings can be divided into electrically insulated deep groove ball bearings, electrically insulated angular contact ball bearings, electrically insulated cylindrical roller bearings, Insulated taper roller bearings, inner or outer ring insulated bearings with oxide coatings, and hybrid bearings with electrically insulated ceramic rolling elements and so on.
Insulated deep groove ball bearings are suitable for high-speed and even very high-speed operation, and are very durable and do not require frequent maintenance. This type of bearing has a small friction coefficient, high limiting speed, and a wide range of sizes and forms. It is used in low-noise motors and other industries. It is the most widely used type of insulated bearing. It mainly bears radial load and can also bear -quantitative axial load.
Insulated angular contact ball bearings can support both radial and axial loads. Can work at higher speeds. The larger the contact angle, the higher the axial load capacity. High-precision and high-speed bearings usually adopt a contact angle of 15 degrees. Under the action of axial force, the contact angle will increase. Inner or outer ring of the insulated bearings with oxide coatings and hybrid bearings with electrically insulated ceramic rolling elements are mainly named for their product characteristics.
Even if the motor is strictly controlled during the manufacturing process, it is difficult to completely avoid the magnetic asymmetry of the armature and the rotor. This asymmetry will generate a voltage between the stators, which will generate a current through the bearing, especially in AC motors, this current generates pits, melting marks, galvanic erosion, discoloration, wear and other damage on the surface of the bearing raceway and rolling elements. Of course, this phenomenon also occurs with motors using inverter and frequency conversion technology. In order to stop this kind of current from flowing through the bearing, it is necessary to cut off the circuit, and the insulated bearing and insulated bearing room have emerged at the historic moment. Insulated bearing chamber is made of a certain hardness of insulating material in the bore and end face of the bearing chamber.

It is the biggest automobile bearing manufacturer in China and the national key bearings export base.
The main bearing products of Xiangyang Automobile Bearing Co., Ltd
Deep groove ball bearing
The deep groove ball bearing is simple in structure and convenient in use. It is a kind of bearing with the largest production batch and the widest application range. It is mainly used to bear radial load. When the radial clearance of the bearing increases, it has the performance of angular contact ball bearing and does not bear the increased axial load. This kind of bearing has small friction coefficient, low vibration and noise, and high limit speed. Not resistant to impact, not suitable for heavy load.
Deep groove ball bearing generally adopts steel plate stamping wave cage, or engineering plastic and copper solid cage. According to the different use environment, the special grease can be added in the sealed bearing.
ZXY can mass produce ordinary deep groove ball bearing with outer diameter less than 260mm. It is used in gearbox, engine, water pump and other parts of all kinds of automobiles, and is suitable for other kinds of machinery. According to the requirements of users, deep groove ball bearings with high precision (P6, P5, P4), various clearance groups, special vibration and noise requirements (Z1, Z2 or V1, V2) can be manufactured.

2. Taper roller bearings
Tapered roller bearings are mainly used to bear the combined radial and axial loads. The larger the contact angle of the outer ring raceway, the greater the bearing capacity of the axial and radial load ratio. The linear contact between the roller and the raceway makes the tapered roller bearing have greater bearing capacity. The bearing is a separate type bearing, and the inner components (inner ring, tapered roller and cage) and outer ring can be installed separately. The characteristics of tapered roller bearing make it an ideal choice in many applications.
The radial and axial clearance of tapered roller bearings can be adjusted in the process of installation and use, and can also be installed with axial preload. The size of axial clearance has a great influence on whether the bearing can work well. When the axial clearance is too small, the temperature rises; when the axial clearance is too large, the bearing is easy to be damaged. Therefore, pay special attention to adjust the axial clearance of the bearing during installation and operation.
ZXY can produce metric series and inch series tapered roller bearings, and also can design and manufacture various non-standard series tapered roller bearings for users. Widely used in automobile differential, wheel hub, gearbox and other parts.
Cylindrical roller bearing
Generally, cylindrical roller bearings are only used to bear radial load, and the roller and the raceway of the ferrule are in linear contact, so they are axial separable bearings. Compared with the deep groove ball bearing with the same dimension, the cylindrical roller bearing has larger radial bearing capacity. The bearing has the advantages of convenient installation and disassembly, impact resistance, good rigidity, limited displacement in axial direction and can not bear axial load alone.
Cylindrical roller bearings have n, Nu, NJ, NUP, RNU, RN and other structural types.
The cylindrical roller bearing of ZXY adopts the structure of optimized design. The internal cage of the bearing has the forms of steel plate stamping, copper solid, engineering plastics and no cage filled with rollers. The convex roller and filled roller structure can effectively improve the radial load capacity of the cylindrical roller bearing.
ZXY cylindrical roller bearing products are widely used in gearbox of various kinds of automobiles and tractors, guide bearing of axle differential, shaft support of water pump, and other machines. They are used in the shaft with good rigidity and axial displacement, and the machine parts that need axial separation bearing for installation and disassembly.
Needle roller bearing
The radial structure of needle roller bearing is compact, its inner diameter and load capacity are the same as other types of bearings, and its outer diameter is the smallest. It is especially suitable for supporting structures with smaller radial installation application. It can only bear radial load. When no inner ring or outer ring is selected, and no inner or outer ring rolling bearing is selected, the hardness, machining accuracy and surface quality of the surface of the shaft or shell hole as the raceway shall be similar to that of the raceway of the bearing ring, so as to ensure that the load capacity and operation performance are the same as that of the raceway bearing.
The structure of needle bearing includes single row and double row K-type, stamping M-type, engineering plastic cage, double half split type, engineering plastic cage structure, etc. The convex machining of the rolling surface of the needle, the surface strengthening treatment of the cage and the uneven distribution of the window hole of the needle are adopted. The transmission needle bearing is often used with the needle bushing.
ZXY can produce all kinds of needle roller bearings, suitable for gearbox, universal joint support, rear axle suspension and other mechanical selection
Clutch release bearing
Clutch release bearing is an important part of automobile. It is installed between clutch and transmission. Because the clutch pressure plate, release lever and engine crankshaft run synchronously, in order to ensure the smooth engagement, soft separation, reduce wear and prolong the service life of clutch and the whole transmission system, it is necessary to make the release lever rotate at the same time through the release bearing Move axially along the clutch output shaft. The disassembly and assembly of clutch release bearing is complex and time-consuming. Therefore, the bearing with high reliability and guaranteed quality can be selected and properly maintained in use, which can prolong the service life of bearing and improve the economic benefits of users.
Wheel hub bearing
Wheel Hub bearing is a special bearing applied to the wheels of automobiles, which bears the weight of the whole vehicle, acceleration force, deceleration force, turning lateral force and vibration and impact force brought by the road conditions. In order to ensure the safety and reliability of braking, anti lock braking system (ABS) is becoming more and more popular. Therefore, the market demand for sensor built-in hub bearing unit is also growing. According to its development, hub bearing can be divided into the first generation, the second generation and the third generation.
Compared with the traditional two sets of single row bearings, the first generation hub bearing integrates the two sets of bearings into one, which is simple and reliable to apply preload, convenient to install, and does not need gasket and midway grease supply. Compact structure, built-in high-performance seal ring, saving installation space and time.
Compared with the first generation hub bearing, the second generation hub bearing does not need to press into the knuckle, so it is more convenient to install, and the preloading is simpler and more reliable. If the outer ring rotates, the sensor rotor can also be installed. The product is lightweight and integrated.
Compared with the second-generation hub bearing, the third-generation hub bearing has been selected and pre tightened by the bearing manufacturer before leaving the factory. It is easier to install the anti lock brake system (ABS) sensor and lighter and more integrated.
7.Cross shaft Bearing
The cross shaft bearing, also known as the cross joint bearing, is mainly used in commercial vehicles. Generally, it is composed of a cross shaft and four stamped outer ring roller bearings. Each outer diameter of the cross shaft needs to be processed with high precision before it can be used as the inner ring of the bearing to contact with the needle roller. The needle roller bearing has a self sealing device, which can prevent dust and grease leakage and improve the service life of the bearing. When it is used, the maintenance personnel shall regularly The hollow bearing through the cross shaft is grease lubricated for the four outer bearings. The cross axle is a part to realize the power transmission of variable angle, which is used to change the direction of transmission axis. It is the “joint” part of the universal drive device of the automobile drive system. The cross axle type rigid universal joint is a widely used non constant velocity universal joint in automobiles. The maximum allowable intersection angle of two adjacent axles is 15 ゜ – 20 ゜. The spider is one of the key parts of the spider type rigid universal joint.

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.

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.

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”.
