2. Bearing is an important component in contemporary machinery and equipment. Used to determine the motion of the axis of rotation relative to other parts.

Position, supporting or guiding components. Its main function is to support the mechanical rotating body to reduce the friction coefficient of the mechanical load of the equipment during the transmission process.

According to the different friction properties of moving elements, bearings can be divided into rolling bearings.

and plain bearings.

3. China is one of the earliest countries in the world to invent rolling bearings, and the structure of axle bearings has long been recorded in ancient Chinese books. Judging from the archaeological relics and data, the oldest bearing in China with the prototype of a modern rolling bearing structure appeared in Yongji County, Shanxi Province, in 221 207 BC (Qin Dynasty).

Xuejiaya Village. The People's Republic of China was

Later, especially since the seventies of the last century, under the strong impetus of reform and opening up, the bearing industry has entered a new period of high-quality and rapid development.

4. Bearing is an important basic component of all kinds of mechanical equipment, and its accuracy, performance, life and reliability play a decisive role in the accuracy, performance, life and reliability of the main engine. In mechanical products, bearings are high-precision products, which not only need the comprehensive support of mathematics, physics and other disciplines, but also need material science, heat treatment technology, precision machining and measurement technology, and numerical control technology.

and effective numerical methods and powerful computer technology.

and many other disciplines to serve, so the bearing is a product that represents the country's scientific and technological strength.

The inner and outer diameters of 6003 bearings are 35mm. Deep groove ball bearings can be used in gearboxes, instrumentation, motors, household appliances, internal combustion engines, transportation vehicles, agricultural machinery, construction machinery, construction machinery, yo-yos and so on.

Spherical roller bearings are mainly used to bear radial loads, and can also bear a certain amount of axial loads, but generally cannot bear pure axial loads. The raceway of the outer ring of this kind of bearing is spherical, and the former residence has self-aligning performance, and when the shaft is bent or tilted and the center line of the inner ring and the center line of the outer ring are not more inclined than that, the bearing can still work normally.

Its structural principle and characteristics are the same as that of self-aligning ball bearings, the only difference is that the rolling elements are spherical rollers, due to the different rolling elements, so its bearing capacity is larger, and it is widely used in mining and heavy machinery. These bearings limit the axial displacement of the shaft or housing within the axial clearance range of the bearing. Spherical roller bearings and spherical ball bearings can be substituted for each other if the capacity and ultimate speed permit.

6203 bearing is a deep groove ball bearing mechanical product, the inner diameter (mm) is 17mm ( the outer diameter (mm) is 40mm ( the width (mm) is 12mm ( weight (kg) is , the basic rated static load (kn) is (, the basic rated dynamic load (kn) is (, the grease lubrication speed (r min) is 16000, and the oil lubrication speed (r min) is 20000.

The inner bore size of the deep groove ball bearing 6003 is 17, the outer diameter size is 35, and the thickness size is 10. The screenshot of the query is as follows.

The difference between 6204 bearings and 6303 bearings:

6204 bearing: means that the bearing has iron dust cover on both sides, and there are both sides, so you can't see the inside of the bearing;

6303 bearing: means that the bearing has a skeleton rubber sealing ring on one side, and only one side is belted.

Note: 2Z is only with iron cover on both sides, and 2RS refers to the skeleton rubber seal on both sides (contact type), good there is a -2RZ also refers to the skeleton rubber seal on both sides, but he is (non-contact), now it is common to replace 2RS with 2RZ. Bearing is an important component in contemporary machinery and equipment.

Its main function is to support the mechanical rotating body, reduce the friction coefficient during its movement, and ensure its rotation accuracy. According to the different friction properties of moving elements, bearings can be divided into two categories: rolling bearings and sliding bearings. Among them, rolling bearings have been standardized and serialized, but compared with sliding bearings, its radial size, vibration and noise are larger, and the highest is also higher.

Rolling bearings are generally composed of four parts: outer ring, inner ring, rolling element and cage, strictly speaking, it is composed of six parts: outer ring, inner ring, rolling element, cage, seal and lubricating oil. It mainly has an outer ring, an inner ring, and a rolling element, which can be defined as a rolling bearing. According to the shape of the rolling elements, rolling bearings are divided into two categories: ball bearings and roller bearings.

The inner diameter size of the deep groove ball bearing 6003 is 17, the outer diameter size is 35, and the thickness size is 10
