Ring bearings, also known as ball bearings, are unsung heroes of the modern world. They are found in countless applications, ranging from bicycles to wind turbines, and play a critical role in ensuring the smooth and efficient operation of machinery.
Ring bearings are a type of rolling-element bearing that consists of a raceway (inner ring), rolling elements (balls), and a cage (outer ring). The balls are interposed between the raceway and the cage, and they roll smoothly as the bearing rotates. This rolling motion reduces friction and allows for high-speed operation.
