    Tips: What is a single row deep groove ball bearing?

    A single row deep groove ball bearing is a type of rolling-element bearing that consists of an inner ring, an outer ring, a set of steel balls, and a cage,which is also called sealed deep groove ball bearings. It is one of the most common types of deep groove ball bearings used in various applications, including motors, pumps, gearboxes, and other machinery. 

    The term "single row" refers to the arrangement of the steel deep groove balls in the bearing. In a single row deep groove ball bearing, the balls are arranged in a single row between the inner and outer rings. This design allows for radial load (perpendicular to the shaft) and axial load (parallel to the shaft) to be supported. 

    The "deep groove" in the name refers to the shape of the raceways on the inner and outer rings. The raceways are curved, forming a deep groove that enables the bearing to accommodate both radial and axial loads. This design also provides high-speed capabilities and low friction. 

    The cage, typically made of steel or synthetic materials, holds the balls in position and prevents them from rubbing against each other. It also ensures proper spacing between the balls for optimal load distribution.

    Single row deep groove ball bearings are available in various sizes and configurations, and they can operate in a wide range of speeds and temperatures. They are known for their simplicity, durability, and versatility, making them suitable for many different industrial and automotive applications.
