NSK Ltd. (NSK; Headquarters: Tokyo, Japan; President and CEO: Toshihiro Uchiyama) Group company, NSK Micro Precision Co., Ltd. (Brand name: ISC), has designed and developed a new gyroscope toy with a super-smooth spinning rotor.
A precision bearing enables highly stable, protracted rotation of the rotor disc, and thereby the gyro itself. Spin Gear Yo-yo Shop exhibited the new gyro at International Tokyo Toy Show 2018 at Tokyo Big Site from June 7-10, 2018.
NSK Micro Precision hopes that these toys will spark interest in the mysteries of science and technology, in both children and adults alike.
NSK Micro Precision developed the gyro in cooperation with former yo-yo world champion, Takehiko Hasegawa, who also worked with the company on the wildly popular NSK fidget spinner (“Saturn Spinner”) in 2017.
The new gyro has a unique design, with a single bearing located in the middle of the rotor disk instead of at the top and bottom of the spin shaft. This reduces friction and contributes to longer idle spinning time. In-house tests show that the gyro can spin for more than four minutes on top of its tiny stand and that the rotor disc can spin for longer than fourteen minutes.
The toy makes use of the gyro effect, which acts to maintain a constant axis of rotation even when an external force is applied. Gyroscopes with ball bearings are widely used for navigation purposes in ships and planes. However, this is the first commercial gyroscope toy in Japan made with a ball bearing.
The extraordinary precision and attention to detail makes the gyro stand out from the crowd. The gyro is completely made-in-Japan, with many components sourced directly in Tokyo and area. This includes the outer rings, which are produced on a high-precision lathe in a machine workshop in Shitamachi, the storied artisan district of Tokyo.
