Bearing classification and introduction of bearing applications in various industries

Bearings can be divided into many types, rolling bearings, radial bearings, ball bearings, thrust bearings and so on.

In terms of its function, it should be support, that is, it is used to support the shaft literally, but this is only part of its function. The essence of support is to be able to bear radial loads. It can also be understood as it is used to fix the shaft. It is to fix the shaft so that it can only achieve rotation, while controlling its axial and radial movement.

The consequence of the motor without bearings is that it cannot work at all. Because the shaft may move in any direction, and the motor is required to only rotate when it is working. Theoretically speaking, it is impossible to achieve the role of transmission. Not only that, but the bearing will also affect the transmission. In order to reduce this effect, good lubrication must be achieved on the bearings of the high-speed shaft. Some bearings are already lubricated, which are called pre-lubricated bearings. Most bearings must have lubricating oil. When running at high speeds, friction will not only increase energy consumption, but even more frightening is that it is easy to damage the bearings.

The idea of turning sliding friction into rolling friction is one-sided, because there is something called a sliding bearing.

The role of bearings in the industry:

1. Endurance bearings for rolling machinery and equipment in smelters, mines and steel plants.

2. High-requirement bearings for power equipment in power plants, gas turbines, and electrical plants. This type of equipment mostly runs continuously, bearing heavy stress, troublesome assembly and disassembly, and inconvenient replacement. Therefore, the bearing quality is required to be very stable, wear-resistant and pressure-resistant. Generally, manufacturers use imported bearings, such as Swedish SKF bearings, German FAG bearings, Japanese NSK bearings, KOYO bearings and other imported bearing brands.

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

4. Plastics, chemical fiber machinery, film stretching, special bearings and high temperature bearings. With the development of science and technology, this kind of mechanical equipment is continuously improved and changes are changing with each passing day; some foreign countries and domestic ones will soon have them, and the bearings matched with them are also being updated. The conveyor belt part is mostly the outer spherical bearing of Dongguan TR and Nan'an Taiwanese FS brand, which is easy to install, beautiful and easy to replace, and is favored by users. Some important parts of the host adopt imported bearings. At the same time, joint bearings, one-way bearings, guide rail bearings, needle roller bearings, BOPP, high temperature bearings in the drying box of PVC stretch film equipment, etc.

5. Fine axis zero for toys, clocks, electronics, audio and video equipment.

6. Select bearings for textile, washing and dyeing, shoe-making and tobacco machinery. This type of bearing is small and exquisite, efficient and durable, requires high speed and low noise, and cannot be manufactured by non-strength famous factories. Because of its strong equipment specificity, different designs, and different bearings, it is generally not available in stock, and sometimes it is not easy to find (only frequent customers can understand it in case of emergency), so it is recommended that the user is best Achieve one for one use, to avoid stoppage waiting for parts, affecting production.

7. Selection of bearings for beer, beverage equipment and medical equipment.

8. Select bearings for crushing, ceramic machinery, and fine chemical machinery. The working environment of this kind of equipment is poor, and it is mostly affected by water mist, humidity, dust, acid and alkali. It is required that the bearing has a strong sealing performance, and the grease is sufficient and reasonable. It is best to add grease in a timely manner. The company always stocks the stock, especially the large UC series bearings (such as: UCFS318 to UCFS328, RME100, RME090S, etc.) and three types of spherical roller bearings, with complete varieties for selection.
