Inspiring NSK Bearing Stories

1. The Space Shuttle's Silent Flight

During the Space Shuttle's inaugural launch in 1981, a faulty bearing in one of the spacecraft's main engines generated excessive noise and vibration. With the mission in jeopardy, NASA engineers turned to NSK for a solution. NSK responded by designing a new bearing with a unique noise-dampening design, which was installed on the subsequent Space Shuttle missions, enabling quieter and smoother flights.

2. The Lesson of the Squealing Train

In 1950s Japan, a passenger train plagued by persistent squealing caused by worn-out bearings disrupted the tranquility of commuters. NSK engineers analyzed the problem and developed a new bearing design with improved lubrication and reduced friction. The result was a quieter and more comfortable train ride, demonstrating the transformative power of bearing innovation.

3. The Wind Turbine Marathon

In 2016, an NSK-equipped wind turbine in Germany set a world record by generating electricity continuously for over 20 years without any bearing maintenance. This remarkable feat showcased the exceptional durability and reliability of NSK bearings, proving their ability to withstand the rigors of harsh operating conditions.
