Four Core Technologies plus One

NSK relentlessly pursues innovative technologies and ongoing improvement in the quality of its products to contribute to a safer, more smoothly running society and to protect the global environment, in line with its corporate philosophy. NSK leads the world in the areas of bearings, automotive components and precision machinery and parts. The foundation of these product fields consists of tribology, materials, numerical simulation and mechatronics – NSK’s Four Core Technologies.

These are complemented and additionally shaped by manufacturing engineering, another important strength of NSK.

The systems and products that we have created on the basis of our Four Core Technologies and the ‘plus One’ of manufacturing engineering contribute to the development of industry and to people’s prosperity around the world. In the years to come, NSK will continue its work in advanced technology, providing highly functional, premium products in response to the needs of the market.

Technical Insight

With the help of our Engineers we have created technical articles on bearing performance, features, materials, lubricants, applications, components, and more.

The articles outline problem areas, highlight new developments and talk about everyday considerations for bearing selections. >>

Tribology (Friction Control Technology)

Good lubrication is vital to bearings that have to withstand linear and rotational loads. Thanks to improved grease formulations and surface processing methods, we´re in a position to develop faster, quieter and more durable bearings capable of sustaining the heaviest of loads.

Numerical Simulation

As part of our product development, computer simulations play an essential role in the process. Through them, we can not only assess our products under extreme conditions, but also gain valuable insights into product design and finishing processes.

Materials are continually being developed in order to improve the functionality and durability of rolling bearings. And NSK is right there at the leading edge. Our research focuses mainly on the areas of material design, heat treatment, performance evaluation and analytical evaluation. The results of this research go straight back into our products.


Through the combination of mechanics and electronics, key advances in high-performance motors, control technology, highly precise sensing technology and biomedical microelectromechanical systems become possible. Mechatronics also play an important role in assembly technology applications that demand high temperatures, power density and reliability.
