In the realm of engineering, bearing balls stand as unsung heroes, playing a crucial role in countless applications. These microscopic spheres, meticulously crafted from materials like steel, ceramic, and plastic, enable seamless motion and reduce friction in a wide array of devices.
Bearing balls are spherical elements that are used in ball bearings, a type of rolling-element bearing. These bearings consist of an inner and outer ring, with the bearing balls positioned between them. As the inner ring rotates, the bearing balls roll and slide, transmitting motion between the two surfaces.
