Bearings, mechanical fixed parts. While other parts to each other when the shaft relative motion, used to maintain the axis of the central location and control of parts of the movement, it is called bearings. Ball bearing means is a rolling body is a ball rolling bearing, miniature ball bearings for the nominal diameter size range of rolling bearing 26mm or less. General said bearing more for rolling bearings. Rolling is the sliding friction shaft and the shaft will run between the seat becomes rolling friction, thereby reducing the friction loss of a precision mechanical components. Rolling generally consists of an outer ring, inner ring, rolling elements and a cage. Rolling easy maintenance, reliable, good starting performance, at moderate speed higher carrying capacity. Comparison with the sliding bearing, the radial rolling bearing large size, poor damping capacity, high speed, low life, sound larger.
