Nippon Seiko K.K. (Headquarters: Shinagawa-ku, Tokyo; Representative: Akihisa Ichii, Representative Director and CEO; hereinafter NSK) has newly developed ball screws for Advics' new regenerative cooperative brake system and has commenced mass production of these products at its Saitama Plant (Hanyu City, Saitama Prefecture).
1. Background of Development
In recent years, the demand for autonomous driving has been increasing, and the adoption of electro-hydraulic brake systems is progressing globally. Among these, ball screw type systems are gaining wider adoption due to their excellent responsiveness in both forward and reverse operation, making them highly compatible with collision damage mitigation braking.
2. Features of the Newly Developed Ball Screw
This product achieves high reliability by adopting newly developed materials. Furthermore, by leveraging NSK's bearing production expertise to integrate the ball screw in the circulation part and functionally integrate it with support bearings and peripheral components, it contributes to the miniaturization and lightweighting of this brake system. These improvements not only save energy and resources during manufacturing but also improve fuel and electricity efficiency when the car is in use, thereby contributing to carbon neutrality.
3. Future Plans
Moving forward, against the backdrop of increasing demand for automotive safety and comfort, NSK plans to contribute to the advancement of electric brake technology while appropriately expanding its production system.
