What is the difference between ball bearings and rolling bearings?

1. The ball bearing is a type of rolling bearing. A spherical alloy steel ball is installed between the inner and outer steel rings to reduce friction during power transmission and improve the transmission efficiency of mechanical power in a rolling manner. Ball bearings cannot withstand heavy loads and are more common in light industrial machinery. Ball bearings are also called ball bearings.
2.Rolling bearing (rolling bearing) is a kind of precise mechanical element that changes the sliding friction between the running shaft and the shaft seat into rolling friction, thereby reducing the friction loss. The rolling bearing is generally composed of four parts: an inner ring, an outer ring, a rolling element and a cage. The role of the inner ring is to cooperate with the shaft and rotate with the shaft; the outer ring is to cooperate with the bearing seat and play a supporting role; In the cage, the rolling elements are evenly distributed between the inner ring and the outer ring, and their shape, size and number directly affect the service performance and life of the rolling bearing; the cage can evenly distribute the rolling elements and guide the rolling elements to rotate for lubrication.
