A deep groove ball bearing is a type of rolling-element bearing that features deep, symmetrical raceway grooves on both the inner and outer rings.
These grooves, along with the balls that serve as the rolling elements, allow the bearing to handle both radial and axial loads, albeit primarily radial. The deep groove design also provides high precision and low friction, enabling smooth and efficient rotation at high speeds.
Deep groove ball bearings are highly versatile and are the most commonly used bearing type due to their simple design, durability, and ability to operate quietly and with minimal maintenance. They are widely used in various applications, including electric motors, household appliances, automotive components, industrial machinery, and even in precision instruments, where reliable and efficient performance is crucial.
