A single row deep groove ball bearing is a type of rolling-element bearing that uses balls to maintain the separation between the bearing races. It 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.

A single row deep groove ball bearing is designed to carry radial loads, and it is suitable for high-speed operation. It is relatively simple in design and is relatively inexpensive compared to other types of bearings. It is also easy to maintain and is durable, making it suitable for use in a variety of environments.

Single row deep groove ball bearings are used in a wide range of applications, including electric motors, pumps, gearboxes, and other mechanical systems. They are commonly available in a range of sizes, with the most common sizes being identified by their bore diameter and outer diameter.
