A ball bearing, as a type of rolling bearing, is characterized by its core structure consisting of spherical alloy steel balls cleverly installed between an inner and outer steel ring. This design allows for significant reduction of friction during power transmission through the rolling of the steel balls, thereby improving the efficiency of mechanical power transmission. However, it is worth noting that ball bearings are not suitable for bearing excessively heavy loads; therefore, in mechanical applications, they are more commonly found in light industrial fields. Additionally, ball bearings are often referred to as ball bearings.
