NSK Begins Mass Production of Newly Developed Ball Screws for Advics' New Regenerative Cooperative Brake System

Nippon Seiko Co., Ltd. (Headquarters: Shinagawa-ku, Tokyo; Representative Director, President and CEO: Akihisa Ichii; hereinafter "NSK") has newly developed a ball screw for Advics' new regenerative cooperative brake system and has begun mass production of this product 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 spreading globally. Among these, the ball screw type is highly compatible with collision damage mitigation brakes due to its excellent responsiveness in both forward and reverse operation, leading to its expanding adoption.

2. Features of the Newly Developed Ball Screw This product achieves high reliability by adopting newly developed materials. Furthermore, by integrating the ball screw with the circulating part using bearing production know-how, and by integrating functions with support bearings and peripheral parts, it contributes to the miniaturization and weight reduction of this brake system. These improvements contribute to carbon neutrality by saving energy and resources during manufacturing, as well as improving fuel and electricity efficiency when used in vehicles.

3. Future Plans Going 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.
