NSK Successfully Developed "Low-Friction Ball Bearings" for Motorcycle Wheels

Nippon Seiko Co., Ltd. (hereinafter referred to as "NSK", the head office / Shinagawa-ku, Tokyo, chairman, and representative executive manager Otsuka Otsuka) successfully developed a "low-friction ball bearing" for motorcycle wheels. The developed product greatly reduces the friction loss while ensuring the sealing performance, and contributes to the reduction of fuel consumption. NSK is mainly investing in emerging markets where the motorcycle market is rapidly expanding. It is expected that global sales in 2015 will reach 1 billion yen (approximately RMB 80.6 million).

[Development background]

Motorcycles in emerging countries as a means of transport, the market continues to grow. Especially in emerging countries, in order to ensure the durability of bearings used on motorcycle wheels, there has been a continuous demand for water resistance and dust resistance based on high sealing performance. Secondly, in recent years, with the emission limits and rising fuel prices, the low fuel consumption of motorcycles has become an important issue.

This time, NSK uses seal shape analysis technology and simulation evaluation technology to achieve a significant reduction in friction loss that affects fuel consumption while ensuring sealability.

【product features】

The developed product for motorcycle wheels has specifically designed the optimum length, thickness, and shape of the sealing lip, which ensures the sealing performance while reducing the friction loss.
