As a commonly used type of rolling bearing, standard deep groove ball bearings have the characteristics of simple and compact structure, convenient installation and maintenance, wide applicable speed range, and excellent radial bearing capacity. They can be adapted to light and medium load rotating conditions of various general machinery and transmission equipment, and are widely used in industrial production, electromechanical equipment and other fields.
