**Description**
Deep groove ball bearings are non-separable and require minimal maintenance during service. They are capable of operating at high speeds and are widely used as radial bearings. The inner and outer rings of single-row deep groove ball bearings have a deep groove raceway, allowing them to carry both radial loads and some axial loads in two directions. These bearings can handle significant axial loads when the radial clearance increases, making them suitable for applications where high-speed angular contact ball bearings would typically be used.
They come in various structural types, including open, shielded, or sealed versions.
