The inner and outer ring raceways of deep groove ball bearings have arc-shaped deep grooves, and the channel radius is slightly larger than the ball radius. Mainly used to withstand radial loads and also withstand certain axial loads. When the radial clearance of the bearing is increased, it has the function of angular contact ball bearing, can withstand large axial load, and is suitable for high-speed rotation. When the bearing hole and the shaft are inclined by 8′~16′, the bearing can still work normally, but it affects its service life. This type of bearing can withstand pure axial loads in the case of high rotational speeds and the use of thrust ball bearings.

Deep groove ball bearings generally use a two-part steel plate stamping cage, but large-size or high-speed bearings use a solid cage. This cage is guided by the ball like a stamped cage, and the high-speed deep groove ball bearing is maintained. The frame is usually guided by the inner or outer ring ribs.

Compared with other types of bearings of the same size, deep groove ball bearings have low friction coefficient, low vibration and noise, high limit speed and high precision, which is the preferred bearing type for users. However, this type of bearing is not resistant to impact and is not suitable for heavy loads.

The deep groove ball bearing has a simple structure and is easy to use, and is a type of bearing with the largest production batch and the widest application range. Widely used in automobiles, home appliances, machine tools, motors, pumps, agricultural machinery, textile machinery and many other fields. Its output accounts for more than 70% of the total bearing output, and it is the most popular and cheapest type of bearing in China.

Deep groove ball bearings are the most common type of rolling bearings. The basic deep groove ball bearing consists of an outer ring, an inner ring, a set of steel balls and a set of cages. The types of deep groove ball bearings are single row and double row. The single row deep groove ball bearing type code is 6, and the double row deep groove ball bearing code is 4. The utility model has the advantages of simple structure and convenient use, and is the most common and widely used type of bearing.

Deep groove ball bearings are mainly subjected to radial loads and can also withstand radial loads and axial loads. When it is only subjected to radial loads, the contact angle is zero. When the deep groove ball bearing has a large radial clearance, it has the performance of an angular contact bearing and can withstand a large axial load. The deep groove ball bearing has a small friction coefficient and a high limit speed.

The deep groove ball bearing has a simple structure and is easy to achieve high manufacturing precision compared with other types, so it is easy to be mass-produced in series, and the manufacturing cost is also low, and the use is extremely common. In addition to the basic type, deep groove ball bearings also have various modified structures, such as: deep groove ball bearings with dust cover, deep groove ball bearings with rubber seals, deep groove ball bearings with snap grooves, and Deep groove ball bearing with large load capacity of ball notch, double row deep groove ball bearing

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-yo, etc.

Deep groove ball bearings mainly support and reduce friction in the machine. Therefore, the accuracy and noise of deep groove ball bearings are directly related to the use and life of the machine. However, business people often encounter customers who use the best deep groove ball bearings or imported deep groove ball bearings, and the efficiency is not high, which is related to the use and selection of deep groove ball bearings. Some people may say that the use and selection of deep groove ball bearings is a matter for the user. I only want what the user wants me to sell. However, as a qualified salesman, besides mastering the knowledge of its own products, it must be proficient in the use of products, that is, doctor-type sales, and select the best supporting deep groove ball bearings according to the performance and use conditions of the user’s accessory products. This is the popular professional manufacturing and sales of major companies in the world. This method has also achieved good results since the implementation of the People’s Group.

Because of the wide range of deep groove ball bearings, the following sections will focus on the use and selection of deep groove ball bearings with the widest range of applications. Those who wish to know less about deep groove ball bearings can deepen their understanding of deep groove ball bearings.
