Ball cages, also known as ball retainers or ball bearings cages, are mechanical components used in ball bearings to keep the balls separated and evenly spaced within the bearing raceways. They are typically made of metal or plastic and are designed to hold the balls in place while allowing them to rotate freely. Ball cages are an essential part of ball bearings, as they help to reduce friction and wear, increase the lifespan of the bearing, and improve its overall performance. The design of ball cages can vary depending on the specific application and type of bearing. Some ball cages are made up of a series of pockets or slots that hold the balls in place, while others use a more intricate design with a series of interconnected wires or rods. The shape and size of the ball cage can also vary, with some cages being circular or hexagonal in shape, and others being more complex. Ball cages are commonly used in a wide range of industrial applications, including automotive, aerospace, and manufacturing. They are used in everything from conveyor systems and robotics to medical equipment and power tools. In addition, ball cages are also used in consumer products such as bicycles, skateboards, and roller skates. Overall, ball cages are an essential component of ball bearings, helping to ensure smooth and efficient operation in a wide range of industrial and consumer applications.
