Single row deep groove ball bearing is the most representative structure of rolling bearings and has a wide range of uses. The raceways located on the inner ring and the outer ring have an arc cross section with a radius slightly larger than the radius of the rolling ball. In addition to bearing radial load, it can also bear axial load in two directions. Low friction torque, most suitable for applications requiring high speed rotation, low noise and low vibration. This kind of bearing, in addition to the open type, also has a bearing with a steel plate dust cover, a bearing with a rubber seal, or a bearing with a snap ring attached to the outer diameter of the outer ring. Generally, steel stamping cages are used. Mainly applicable cage: steel stamping cage (wave shape, crown shape...single row; S shape...double row)
