A deep groove ball bearing is a type of rolling bearing that is designed to support radial and axial loads. It is one of the most commonly used types of rolling bearings in various applications, including automotive, industrial, and household appliances.

Deep groove ball bearings have a simple design that consists of an inner and outer ring, a cage, and a number of rolling elements, typically balls. The raceways on the inner and outer rings are designed to create a deep groove that allows the rolling elements to move freely and reduce friction.

One of the key advantages of deep groove ball bearings is their versatility and suitability for a wide range of applications. They can handle both radial and axial loads and operate at high speeds.

Deep groove ball bearings are available in a variety of sizes and configurations to meet specific application requirements. They can be manufactured with various materials, including stainless steel, ceramic, and plastic, to provide corrosion resistance, temperature resistance, or other specialized properties.

Overall, deep groove ball bearings are reliable, cost-effective, and widely used in a range of applications. They provide high performance and long service life, making them a popular choice among designers and engineers.
