Miniature Ball Bearings are small bearings with balls as their rolling elements, and these small bearings have an outside diameter of less than 9mm. F, MF series deep groove ball bearings with flanged outer rings correspond to ordinary ball bearings with snap rings. The flange extends around the entire circumference of the outer ring due to the size limitation and to improve its running accuracy. Since it is no necessary to provide a shoulder on the housing bore if this bearing is used, the bore can be a simple cylindrical shape which facilitates high precision machining and also reduces the machining time.

In general, the cages used in miniature bearings are either ribbon cage or snap cages, both options are made of pressed steel. Pressed steel ribbon cages are used in the larger bearings and pressed snap cages in the smaller ones. In addition, the plastic snap cages option is also available, as it has the advantages of low torque, long grease life and low noise.

Application

The miniature deep groove ball bearings are widely used in miniature mechanical engineering, electronic and medical devices, miniature engines and dynamic model building, small spindles, dental drills, watches, aerospace and all applications requiring extremely small components.
