Koyo 6305Dd Ball Bearing

A ball bearing is a type of rolling-element bearing that uses balls to maintain separation between the bearing races (the inner and outer rings) and support radial and axial loads. The balls enable smooth, low-friction rotational motion by minimizing contact surface area and friction between the moving parts of the bearing. Ball bearings are commonly used in various applications where precise rotation and reduced friction are critical, such as in automotive systems, industrial machinery, and household appliances. They come in different designs and materials to suit specific operating conditions and load capacities.
