What results from a larger number of balls in a ball bearing configuration?

A larger number of balls in a ball bearing configuration contributes to a greater radial load capacity primarily because the load is distributed across more contact points. This distribution allows the bearing to support heavier loads without excessive wear or failure. With more balls, each individual ball bears a smaller portion of the total load, which enhances the overall strength and durability of the bearing.

Additionally, more balls can enhance the bearing's ability to handle misalignment and other operational stresses. This improvement in load capacity is critical in applications where bearings endure substantial forces or operate under challenging conditions.

While other factors, such as design and materials, also influence performance, the principle of load distribution is central to understanding how increasing the number of balls affects the load capacity of the configuration.
