Starter Motor

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.

Throttle Body

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.

Wiper Motor

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.

MinebeaMitsumi developed a high-performance ball bearing is designed for quiet, smooth EV operation.

Optimized materials and advanced technologies—such as ceramic balls, a heat-resistant cage, and non-contact seals—enable high-speed rotation, improved motor responsiveness, and enhanced electric-corrosion resistance.

The ceramic balls reduce inertia for quicker acceleration, while the rigid, heat-resistant cage ensures stability at high speeds. Non-contact seals prevent grease leakage and keep the bearing clean, increasing reliability and reducing maintenance needs.

By boosting efficiency and durability, this bearing enhances electric vehicle motor performance and supports more sustainable mobility.
