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 low friction coefficient, high limit speed, simple structure, low manufacturing cost, high precision, no need for frequent maintenance, large size range and many forms, and it is the most widely used type. Bearing. It mainly bears radial load, but also can bear certain axial load. When it only bears radial load, the contact angle is zero.
After the deep groove ball bearing is installed on the shaft, the axial displacement of the shaft or the housing can be restricted within the axial clearance of the bearing, so it can be axially positioned in both directions. When the deep groove ball bearing has a larger radial clearance, it has the performance of an angular contact bearing and can bear a larger axial load. Under high-speed operating conditions with large axial loads, deep groove ball bearings are more advantageous than thrust ball bearings. In addition, this type of bearing also has a certain degree of aligning ability. When it is inclined 2'-10' with respect to the housing hole, it can still work normally, but it will have a certain impact on the life of the bearing.
