Deep groove ball bearings are the most representative rolling bearings. Compared with other types of bearings of the same size, this type of bearing has the lowest friction coefficient, high speed limit, simple structure, low manufacturing cost, high precision, no need for frequent maintenance, and large size and form. It is the most widely used type. Bearing. It is mainly subjected to radial loads and can also withstand certain axial loads. When it is only subjected to radial loads, the contact angle is zero.
After the deep groove ball bearing is mounted on the shaft, the axial displacement of the shaft or the casing can be restricted within the axial clearance of the bearing, so that the axial positioning can be performed in both directions. 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. Deep groove ball bearings are superior to thrust ball bearings in high-speed operating conditions with large axial loads. In addition, this type of bearing also has a certain ability to adjust the core. When it is inclined 2'~10' with respect to the hole of the housing, it can still work normally, but it has certain influence on the bearing life.
