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 a low friction coefficient, high limit speed, simple structure, low manufacturing cost, high precision, no need for regular maintenance, and a wide range of sizes and forms. It is the most widely used type of bearing. It mainly bears radial loads and can also bear a certain amount of axial load. When it only bears radial loads, the contact angle is zero. After the deep groove ball bearing is installed on the shaft, the axial clearance of the bearing is within the specified range
