What is deep groove ball bearing? What are its characteristics?
Deep groove ball bearings are commonly used in motors. Deep groove ball bearing, as the name implies, is a kind of spherical rolling bearing
Type A, bearing centripetal load. In the field of industrial motors, the use of deep groove ball bearings accounts for more than 70 percent of the total use of bearings. In terms of usage, this proportion will be larger.
Therefore, if electrical engineers can be very familiar with the mastery of deep groove ball bearings, they can understand the application of motor bearings to a large extent.

The characteristics of Cheng!
The bearing capacity of the deep groove ball bearing is weaker than that of the roller bearing, which is less than that of the corresponding roller bearing, but is sufficient for general industrial motors. Usually for external pulleys and their
In case of additional radial load, its load capacity may not meet the requirements, and cylindrical roller bearing can be selected.
The friction inside the bearing is relatively small, the heat is relatively small, the point contact between the rolling element and the raceway is small, and the heat inside the bearing is relatively small. In the case of bearings with seals, the friction and heating of the seals need to be considered.
The inner rolling element of deep groove ball bearing of high-speed bearing is a ball. Compared with roller bearing, the mass of rolling element is relatively small, and the centrifugal force during high-speed rotation
Small, while the commonly used stamping rigid support and nylon support have relatively good strength, so the mechanical limit speed capacity of deep groove ball bearing is relatively high.
Therefore, due to the relatively small heat, the thermal reference speed capacity of deep groove ball bearings is relatively high. 4. Simple bearing arrangement
Deep groove ball bearing can not only bear axial load, but also bear radial load, so this kind of bearing can be used as locating end bearing or non locating end bearing
The deep groove ball bearing is usually an integrated bearing structure, so the installation, storage and transportation of the bearing is simpler than that of the split bearing.
Simple maintenance In general, the deep groove ball bearing is open type with dust cover and seals, which greatly simplifies the workload of bearing supplementary lubrication and is characterized by simple operation.
