Deep groove ball bearings consist of an inner ring, an outer ring, a set of balls, and a cage to keep the balls separated and evenly spaced. The inner and outer rings are typically made of steel, while the cage can be made of various materials such as brass, plastic, or steel. They are one of the most widely used types of bearings due to their versatility and relatively low cost.
Deep groove ball bearings are used in a wide range of applications, from household appliances and electric motors to heavy machinery and automotive systems. They are often used in high-speed and high-precision applications due to their low friction and high reliability.
