Achieving twice the permissible rotational speed of standard bearings! Deep groove ball bearings with improved high-speed performance.

We would like to introduce the "Grease Lubricated High-Speed Deep Groove Ball Bearings for EV/HEV" that we handle. Combining a resin retainer developed for high-speed rotation with grease, we provide optimal performance. The lightweight, high-strength resin retainer employs resin materials and shapes that enhance high-speed capability, heat resistance, and lubrication. The grease designed to improve high-speed lubrication performance enhances lubrication during high-speed rotation through the optimization of grease components. It utilizes grease that exhibits high lubrication and low heat generation over a wide temperature range. 【Features】 ■ Improved lubrication due to lightweight, high-strength resin retainer ■ Reduction of inertial forces and lightweight retainer ■ Reduction of centrifugal deformation (1/8 compared to standard resin retainers) ■ Reduction of rotational torque through optimization of materials and shapes ■ Ensured lubricant supply to the raceway surface through improved pocket shape (grease groove) ■ Heat resistance improved by 30°C, material strength increased by 1.6 times *For more details, please download the PDF or feel free to contact us.
