The more common bearings in motors are deep groove ball bearings. Deep groove ball bearing, to put it bluntly, this kind of bearing is a ball type of inverted bearing, bearing radial load. In the industrial production motor industry, the consumption of deep groove ball bearings accounts for 70 percent of the total consumption of bearings. That would make the ratio even higher in terms of usage.

Therefore, if electrical engineering engineers can be very familiar with the grasp of deep groove ball bearings, they can master the application of motor bearings to a large extent.

Bearing axial load capacity than roller bearing bearing bearing weak deep groove ball bearing capacity is lower than the corresponding roller bearing bearing bearing bearing, but enough for general industrial motors. Generally for the outside belt disk and his additional axial load standard, its load capacity is likely to not meet the requirements, then you can choose cylindrical roller bearings.

The rolling friction force of bearings is relatively small, the contact force between the rolling body and the dovetail guide rail is relatively small, and the heat of the internal structure of bearings is relatively small. If it is a bearing containing hydraulic seals, the friction and heating of sealed parts should be considered.

The structural rolling element of fast bearing deep groove ball bearing is a ball. Compared with roller bearings, the quality of rolling body is relatively small, and the centripetal force during high-speed operation is relatively small, while the common stamping processing stiffness support frame and polyester support frame have relatively good strength, so the machine speed conversion ability of deep groove ball bearings is also high. Therefore, because the calorific value is relatively small, the thermal reference rate capacity of deep groove ball bearing is relatively high. 4. Simple bearing layout deep groove ball bearings can withstand both radial load and axial load, so such bearings can do accurate positioning end bearings and non-accurate positioning end bearings

Deep groove ball bearings are generally integrated bearing structures, so bearing installation, storage and transportation are more convenient than separated bearings. In general, the deep groove ball bearing is open, containing sealing cover and hydraulic seals, greatly simplifying the bearing filling and wetting workload, with the characteristics of easy to use.
