Single-row ball slewing bearing as the most widely used slewing bearing, has a single row of balls that contact the raceway at four points. This structure allows it to handle forces from multiple directions all at once. It is popular for medium-load applications, such as infrastructure construction, mining excavation, cranes, concrete pumps, and other medium-duty construction scenarios.
