Features:
Miniature ball bearings have a wide range of functions. Bearings are devices that allow parts to move relative to one another in a constrained fashion. The two most common types of bearings are plain bearings and rolling bearings. The most well-known of the rolling variety of bearings is the ball. A ball bearing can be highly effective in reducing friction between two parts that need to move freely.
