Deep groove ball bearings are the most common rolling bearings, with simple structure, easy use and wide range of applications. This type of bearing is a non-separable bearing whose inner ring and outer ring are rolled into a grooved arc, which can bear radial load and axial direction.
The features like low friction coefficient and high limit speed,are suitable for high speed, low noise and low vibration occasions.
