Simple structure: It consists of an inner ring, an outer ring, rolling elements (steel balls) and a cage. This simple structure makes it easy to manufacture and install, and the cost is relatively low.

Low friction resistance: The rolling elements and raceways of deep groove ball bearings are in point contact, with a small friction coefficient, which can maintain low energy loss at high speeds, thereby improving mechanical efficiency.

High speed: Due to low friction and low heat generation, it is suitable for high-speed rotation occasions, can work stably at high speeds, and has good high-speed performance.
