What are the three major bearing factories in China?

Harbin Bearing Group, Luoyang Bearing Group and ZWZ Group, they account for 15% of China's bearing market share.

1. Harbin Bearing Factory was founded in October 1950 to "resist US aggression and aid Korea."

In the early stage, in accordance with the strategic deployment of the first class, Wafangdian in Fuxian County, Liaoning Province.

The bearing factory was relocated to Harbin and built on the basis of two flour mills in Xiangfang District, which had long ceased production. Under the leadership of the party, in the past 35 years, after continuous expansion and development, it has not only become the second birthplace of China's bearing industry, but also one of the large-scale backbone enterprises of the national machinery industry. In all periods of national economic development, it has made positive contributions and played an important role, writing a glorious chapter in the history of China's bearing development.

2. Luoyang LIC Bearing, formerly known as Luoyang Bearing Factory, is one of the 156 key construction projects during the national "First Five-Year Plan" period, and is one of the largest comprehensive bearing manufacturing enterprises in China's bearing industry. It has a national technology center and has an aero engine.

Bearings, rail transit vehicle bearings, special bearings for major equipment and other core technologies, is currently the birthplace of China's largest processing diameter, the highest precision bearing, China's wind power generator bearing standard setting unit, China's first set of extra-large rolling mill bearing production unit, but also the domestic bearing product size of the widest, the widest coverage, the most complete variety of production base, maintained a number of Chinese bearing industry records.

3. The predecessor of Wafangdian Bearing Factory is Manchuria Bearing Manufacturing Co., Ltd. Lugou Bridge.

The second year of the incident, Japanese imperialism.

In order to realize the ambition of invading China, the policy of "feeding the war with war" was implemented, and a large-scale machinery factory was established in the northeast of our country. According to relevant statistics, in 1938 Japan was in the puppet state of Manchukuo alone.

More than 200 new machine factories were built.

Bearing is an important component in contemporary machinery and equipment. Its main function is to support the mechanical rotating body and reduce the coefficient of friction during its movement.

And ensure its rotation accuracy.

Jiangsu Luyue Bearing Manufacturing Co., Ltd. specializes in the production of high-temperature resistant bearings, stainless steel bearings, and spherical bearing seats.

The three major bearing manufacturers in China are: Harbin Bearing Group, Luoyang Bearing Group and ZWZ Group.

1. Harbin Bearing Group, Harbin Bearing Group Co., Ltd. is one of the three major production bases in China's bearing industry, with total assets of 100 million yuan in 2012, more than 4,600 sets of main production equipment, and an annual production capacity of 80 million sets. It can produce nine types of bearings with more than 6,000 specifications and varieties of various precision levels. (as shown in the image below).

2. Luoyang Bearing Wushi Group, process design, production and sales of bearings and their spare parts, abrasives, cemented carbide, clamp abrasives, industrial machinery and equipment (excluding special equipment). Hardware and electricity, clothing sales, computer software development. (as shown in the image below).

3. ZWZ Group, Wafangdian Bearing Group Co., Ltd. was founded in 1938, and its comprehensive economic and technical indicators ranked first in the domestic bearing industry and twelfth in the world. (as shown in the image below).

Criteria for bearing selection:

1. Selection of bearing model: The bearing model is generally selected by the user's technical personnel according to the use conditions and load of the supporting products. Business personnel mainly understand whether the user's actual load is consistent with the selected bearing, if the bearing does not meet the use requirements, it should be recommended that the customer change the model as soon as possible, but unless the special product in the selection of the model will generally not have any problems.

2. The choice of bearing clearance: the user will generally only inform what model and grade when buying the bearing, and rarely will put forward requirements for the clearance of the bearing, and the business personnel must ask about the use conditions of the bearing, in which the rotation speed, temperature and fit tolerance of the bearing are directly related to the choice of bearing clearance.

3. The selection of grease: the selection of grease is generally based on the speed of the bearing, temperature resistance, noise requirements and starting torque, etc., which requires business personnel to have a good understanding of the performance of the grease of the orange pants. <>
