A radial deep groove ball bearing is a type of rolling-element bearing that uses balls to maintain the separation between the bearing races. The design of a radial deep groove ball bearing allows it to carry both radial and axial loads, and it is suitable for high-speed operation.

The bearing consists of an inner ring, an outer ring, and a set of balls that are retained in place by a cage. The inner and outer rings are typically made of steel, while the balls are made of a harder material such as steel or ceramic. The bearing is lubricated with oil or grease to reduce friction and wear.

Radial deep groove ball bearings are used in a wide range of applications, including electric motors, pumps, gearboxes, and other mechanical systems. They are relatively simple in design and are relatively inexpensive compared to other types of bearings. They are also easy to maintain and are durable, making them suitable for use in a variety of environments.
