Basic Mechanism of Ball Bearings
Ball bearings are essential to all moving components with rotating axis. Ball bearings enable smooth rotation of the shaft by using a low-friction mechanism of rolling balls to promote efficient transmission of kinetic energy to various parts of the machine. This contributes to energy savings, longer life and reduction in breakdowns of the machinery. Bearing precision is linked directly to precision of the machinery.
Automotive Bearing Application Examples
Starter motors require reliable, repeatable performance with a long life span. Special design characteristics enable the bearing to withstand extreme temperature variations, reduced bearing creep, high load capacity and increased sealing performance.
MinebeaMitsumi has supplied this market since the inception of fuel injection and retains top market share of bearings for throttle body applications worldwide. We developed a dedicated rubber seal incorporating a special lip structure, thus reducing air leak across the bearing.
The bearings for wiper motors enable a clear view of the road for drivers and require high reliability and thrust load resistance. In addition, because they are in close proximity to vehicle passengers, they need provide quiet and smooth operation.
