Bearing balls are small, spherical components used in various types of bearings, which are mechanical devices that reduce friction between moving parts. These balls are typically made from materials like steel, ceramic, or plastic, and they help support loads while allowing smooth rotation or linear movement. Their size and material can vary depending on the specific application. In a ball bearing, the balls are positioned between two rings, known as the inner and outer races. This design enables the balls to roll smoothly, minimizing wear and tear on the surfaces they contact. Bearing balls are essential in many machines, from automobiles to industrial equipment, ensuring efficient operation and longevity.
