The Deep Groove Ball Bearing is the most widely used among the roller bearings. It has simple structure and easy usage. It is mainly used to bear the radial load. The bearing can possess the performance of the Angular Contact Ball Bearing (i.e. support the axial load) by increasing the height coefficient of the rib and increasing the radial clearance. Compared with other bearings with the same dimension, the Deep Groove Ball Bearing is characterized by the lower friction coefficient and higher speed limit, but it has low impact resistance and is not applicable to bearing heavy load.
Within the allowable axial clearance, the bearing mounted can limit the shaft and the axial position of the housing, so it can be used as a bidirectional locating bearing. In addition, due to the arc raceway, the bearing possesses the self-aligning function; therefore, it can still work normally when the angle between inner and outer rings is between 3' and 11'. However, this situation could reduce the service life.
The Deep Groove Ball Bearing is widely used for automobiles, tractors, machine tools, electric motors, water pumps, agricultural machines, textile machines, etc.
The stamped wavy cages made of steel plate are usually used in the Deep Groove Ball Bearing. Additionally, the lathed cages made of solid brass are usually used in the large-size bearings.
