Provide lightweight, low-torque bearings for wheelchairs, allowing athletes to run more smoothly

NTN Corporation (hereinafter referred to as "NTN") provides bearings and technical support related to track and field wheelchair bearings to Mr. Tomoya Ito (belonging to Bayer Pharmaceutical Co., Ltd.) and Mr. Hirokazu Ueyonabaru (belonging to SMBC Nikko Securities, Inc.).

The bearings provided for athletes are deep groove ball bearings, which achieve low torque through ceramic rolling elements and oil lubrication. NTN optimized the strength, torque and stiffness of the bearings to match the wheels of the wheelchair used by the two athletes. NTN and the two athletes repeated trial runs and discussions. Then, according to the strategies and feelings of the athletes, through fine and repeated adjustments, and by setting the best bearing specifications, we finally achieve smooth and stable operation.

NTN will support the two athletes who have achieved brilliant results in international and other competitions to achieve further success by providing bearings and technical support. In addition, NTN will use our accumulated technology and achievements over the years, as well as the knowledge we have gained through this event, to promote the commercialization of health and welfare. Through these efforts, NTN will contribute to the realization of a sustainable "NAMERAKA Society*" by reducing energy loss and providing safe and comfortable products.

* A society where people can easily live a safe and fulfilling life in harmony with nature.
