Nippon Seiko Co., Ltd. (Headquarters: Shinagawa-ku, Tokyo, Representative: Executive Director, Executive Director, Chief Executive Officer, Nakayama Masahiro, hereinafter referred to as NSK), Group affiliate NSK Micro Precision Co., Ltd. (Headquarters: Chiyoda-ku, Tokyo, hereinafter referred to as ISC) successfully developed a gyroscope with a precision bearing that can stably rotate for about 8 minutes even on uneven surfaces (products with weight adjustment rings). The product was released on January 10, 2018.

Toy gyros, one of Japan's traditional New Year's celebration methods, originated in the Edo period. It has been about 400 years old. In order to make the gyro rotate more smoothly, ISC has made many improvements. Because the bearings can reduce the mechanical rotation Friction, improving the smoothness of rotation, so this time, ISC put the bearings favored by champions of the World Yo-Yo Championship on the gyro, and successfully developed the 'throwing gyro', achieving a continuous rotation of about 8 minutes. The continuous rotation of the gyro on uneven surfaces is generally only 2 to 3 minutes.
With a fingertip gyroscope (Saturn name: SATURN SPINNER) that can be continuously rotated for more than 12 minutes sold out on the day of sale in 2017, ISC continues to use its own technology, focusing on innovation and demonstrating to a wide range of people including children. Wonderful science.
A common gyro is a shaft that rotates with a body, and the shaft end comes into contact with the ground to cause friction to stop the gyro from rotating. With a gyro equipped with a bearing, the friction between the shaft end and the ground does not affect the rotation of the gyro body. Smooth continuous rotation on uneven surfaces or fingertips that cannot be operated for long periods of time.
