Analysis of Bearing Industry

  Bearings refer to the mechanical basic parts that support the rotating shaft or other moving bodies, and are used to bear the loads generated during the operation of the shaft and other parts in the shaft and reduce the friction coefficient of the mechanical rotating body. quality and other aspects have a greater impact. Usually consists of inner ring, outer ring, rolling elements, cage, seals and grease.

  After years of development in China, five bearing industry clusters have been formed: Wafangdian in Liaoning, Luoyang in Henan, Jiangsu, eastern Zhejiang and Liaocheng in Shandong. Relying on the different industrial endowments of different regions, the north is dominated by heavy industry, and the south is dominated by automobile production and light industry. Each bearing industry cluster has different advantageous products. The north mainly produces large-scale bearings, the south mainly produces small and medium-sized bearings, and Shandong, relying on its superior geographical location, is the largest bearing trade base in my country.

1. Endurance bearings should be used for rolling and pressing machinery and equipment in smelters, mines and iron and steel plants.

2. The power equipment of power plants, gas turbines and motor plants has higher requirements on bearings. Most of this type of equipment is in continuous operation, the bearing is subjected to large force, the assembly and disassembly are troublesome, and it is inconvenient to replace, so the bearing quality is required to be very stable, wear-resistant and pressure-resistant.

3. Printing, packaging machinery, and food machinery require special bearings and outer spherical bearings.

4. Special bearings and high temperature bearings are also required for plastics, chemical fiber machinery, and film stretching.

5. Fine bearings should be used for toys, clocks, electronics, and audio-visual equipment.

6. Bearings are used for textile, dyeing, shoe-making and tobacco machinery. This type of bearing requires small size, high efficiency and durability, high speed and low noise.

7. Precision bearings are used for beer, beverage equipment and medical equipment.

8. Crushing, ceramic machinery, fine chemical machinery, etc. The working environment of such equipment is poor, and there are many influences such as water mist, moisture, dust, acid and alkali, etc., which require strong bearing sealing, and it is best to add grease in time.
