Deep groove ball bearings are the most widely used type of bearing, especially with multiple functions. This type of bearing has the characteristic of low friction, and after optimization, it can reduce noise and vibration, thereby achieving high speed. Capable of withstanding radial loads and axial loads in both directions, easy to install, and requiring less maintenance compared to other types of bearings.
